XPages sessionScope variable and DateTime values - datetime

I seem to be losing the value of sessionScope variables between XPages when I load DateTime values from a Notes document (not from the XPage). Here is what I do:
I have an EditBox where the contents are set to type Date only:
<xp:inputText value="#{document1.datum}" id="datum" defaultValue="#{javascript:#Now()}" required="true">
<xp:this.converter>
<xp:convertDateTime type="date"></xp:convertDateTime>
</xp:this.converter>
<xp:dateTimeHelper></xp:dateTimeHelper>
</xp:inputText>
I then save this to a sessionScope variable :
sessionScope.put ("datum", getComponent("datum").getValue());
Then I change XPages by doing a:
var extCont = facesContext.getExternalContext();
extCont.redirect("xpNextPage.xsp")
I then do a sessionScope.get:
print (sessionScope.get ("datum"));
And the contents are fine.
if I do the same thing with a document that I have loaded:
var date:NotesDateTime = doc.getItemValueDateTimeArray("datum");
var start:NotesDateTime = doc.getItemValueDateTimeArray("von");
var dt:NotesDateTime = session.createDateTime (date [0].getDateOnly() + " " + start [0].getTimeOnly());
sessionScope.put ("datum", dt);
then switch to the next page and try and load it with:
print (sessionScope.get ("datum"));
I get a value null.
I have attached a screenshot of the problem (I printed other fields as well so you can see it is only the DateTime fields that are the problem). I do notice that the format of the DateTime value is different... could this be the problem?

NotesDataTime is not serializable, so you cannot store it in the memory. When you use getComponent("datum").getValue(), it returns you Java Date not NotesDataTime. Java date is serializable, so its working.
Try convert your NotesDataTime to Java Date.
dt.toJavaDate()

Get time format according to spreadsheet locale?

I want to store a Javascript Date() object in a spreadsheet with correct format according to spreadsheet's locale (SpreadsheetApp.getActive().getSpreadsheetLocale()).
Is there a way to get the country specific (date and) time format string from the spreadsheet locale?
E.g. when locale is de_DE, time format string as hh:mm
but when locale is da_DK, time format string as hh.mm
Interesting as well how to get the countries currency format.
BTW when I have date and time in de_DE and than change to da_DK, dates are reformatted (23.01.2020 -> 23/01/2020) but times are not (it stays as 22:59). Is that an error in Spreadsheet?
Dates in JavaScript have the method toLocaleDateString, which return a string formatted according to the specified locale. But this doesn't seem to work in Apps Script.
If you're open to using an Apps Script Web App for this, you could use this toLocaleDateString in your client-side script (that is, in a script tag in your HTML).
If that's not the case, I think your best option would be to create the relationship between formats and locales yourself, because Apps Script doesn't have a built-in method to achieve that. You could, for example, use a switch statement that would check the locale, and then format the date accordingly with Utilities.formatDate, the tool Apps Script uses to format dates. It could be something along the following lines:
var locale = SpreadsheetApp.getActive().getSpreadsheetLocale();
var formattedDate;
switch (locale) {
case 'de_DE':
formattedDate = Utilities.formatDate(yourDate, yourTimeZone, "hh:mm");
break;
case 'da_DK':
formattedDate = Utilities.formatDate(yourDate, yourTimeZone, "hh.mm");
break;
// ...
}
return formattedDate;
Reference:
toLocateDateString
Apps Script Web Apps
Utilities.formatDate
I hope this is of any help.
Sorry for that, however I found a function that would be worth checking out, it's toLocaleDateString() and toLocaleTimeString (), they deliver the local date and time format.
Please check
Formato fechas JavaScript.
I did the test from Google Apps Script and it throws me the following
function pruebafecha() {
var d = new Date();
var n = d.toLocaleDateString();
var h = d.toLocaleTimeString();
Logger.log(n);
Logger.log(h);
}
This is the answer(Colombia):
[20-01-24 16:47:50:286 EST] 24 de enero de 2020
[20-01-24 16:47:50:287 EST] 16:47:50 EST
A JavaScript Date object includes date, time and timezone. When Google Apps Script pass a Date object to the spreadsheet using setValue() / setValues() the value is displayed according to the cell number formatting using the spreadsheet timezone.
If the cell formatting is set to Automatic by default the date will be displayed accordingly to the spreadsheet locale.
If you want to force the cell to display a date in an specific format use Class Range setNumberFormat / setNumberFormats
If you don't want to use the above methods and don't want to rely on the spreadsheet locale and automatic cell format then instead of passing a Date object pass the value as an string prepending it with an ' (apostrophe, single quote character) to prevent that that automatic data type parsing changes the value and it's format.

Javascript in Google Sheets script: help using setNumberFormat
I don't know very well the configuration of the sheet you mention. However, I share a code that I use to print the date and time of data submission of a form.
var d = new Date();
var hour = d.getHours()-1;
var min = d.getMinutes();
var day = d.getDate();
var month = d.getMonth()+1;
var year = d.getFullYear();
if (month<10) {dia = day+"/"+"0"+month+"/"+year;}
else {dia = day+"/"+month+"/"+year;}
if (min<10){time = hour+":"+"0"+min;}
else {time = hour+":"+min;}
What I do in the code is to take the values โ€‹โ€‹of day, month and year, I add 1 to the value of month because it takes values โ€‹โ€‹[0:11] => [Jan, Dec].
Then I build the format I want from date and time, you can notice that I have 1 left to the hours, because when I did the tests I noticed that the time of the script was one hour above.
I use google translate, I hope it is understood.

Xpages Date Time

I'm going loopy....
I want a date, in date format, for example
21/06/2017 17:23:04 GDT
I stamp this on a document, but I then want to display it on my xpage as:
21/06/2017 17:23
But I keep getting different results no matter what I do. I get the date from the onClick of a button using
var dt = new Date();
I then pass this into a function:
function AddObjectivesHistoryItem(doc, dt, action, username){
var ArrDocHistory:array = doc.getItemValueArray("History");
if(ArrDocHistory.length < 1){
// This should always return an object as it is created when an objectives document is first
// created but do this check to be safe and create an array if for some reason it doesnt exist
ArrDocHistory = [dt+"|"+action+"|"+username];
}else{
// append new value to the array
ArrDocHistory.push(dt+"|"+action+"|"+username);
}
doc.replaceItemValue("History",ArrDocHistory);
doc.replaceItemValue("LastUpdatedByName",username);
doc.replaceItemValue("LastUpdatedDate",dt);
}
I've tried using toLocaleString() and all others it seems but it wont work.
For example, toLocaleString() displays as 13-Mar-2018 15:02:15 on my xpage. It's close to what I want except it uses hyphens instead of slashes, and also displays the seconds.
I've tried using custom date pattern on my date field properties with no luck and I'm certain I'm missing something super obvious!?
Any pointers on how to firstly get the date like 21/06/2017 17:23:04 GDT and store as a date and secondly to then display it as 21/06/2017 17:23, this can be a string if it needs to be.
Thanks
You can get your date value as String in SSJS with:
var dateTimeFormat = new java.text.SimpleDateFormat("dd/MM/yyyy kk:mm");
var dateTimeString = dateTimeFormat.format(dt)));
If you want to store as text, java.text.SimpleDateFormat is best for converting a date server-side to a specific text format. It can also be used in a converter to manipulate to/from as well.

Date field changing from UK to US culture upon SaveChanges (EF6.1)

I am using a custom overloaded SaveChanges to implement some auditing functionality. The functionality works perfectly with the exception of some unexpected behaviour in relation to dates. In this example I'm changing a date field value from 1st May 2014 to 2nd May 2014:
A change is made to the database here:
Public Function UpdateTask(request As DataSourceRequest, ThisTask As JobTasksVM) As JsonResult
Dim cu As ApplicationUser = GetCurrentUser()
Dim CurrentTask = db.events.Find(ThisTask.id)
CurrentTask.start_date = ThisTask.start '<--- 2/5/2014 (ie 2nd May 2014), was previously 1/5/2014
CurrentTask.date = ThisTask.end
CurrentTask.task_name = ThisTask.Title
db.SaveChanges(cu.Employee_id)
End Function
This is intercepted by my custom SaveChanges:
Public Overloads Function SaveChanges(userID As Integer) As Integer
For Each entry As dbentityentry In Me.ChangeTracker.Entries().Where(Function(e) e.State <> EntityState.Unchanged)
Dim startOriginal As DateTime = entry.OriginalValues.Item("start_date")
Dim StartCurrent As DateTime = entry.CurrentValues.Item("start_date")
etc....
The bizarre thing is that whilst CurrentTask.start_date that is committed clearly shows the correct (UK) date of 2/5/2014 (2nd May 2014) the values within the overloaded SaveChanges are:
startOriginal: 5/1/2014 (ie 5th Jan 2014) <-- seems to have changed to US culture
startCurrent: 2/5/2014 (ie 2nd May 2014) <---as expected
I need to use the Original values in my audit functionality so this is causing a problem. I have also tried:
entry.CurrentValues.SetValues(entry.GetDatabaseValues)
But this also loads in the erroneous (ie US format 5/1/2014) into the start_date field.
I've checked all the culture settings on the system and they are all correctly English-UK. This behaviour seems fundamentally inconsistent - am I missing something?!
Thanks
DateTime types do not have a format, they are simply a value (number of ticks since 1/1/0001).
You did not say where you are seeing the "wrong" format, whether ToString() output or in intellisense. If you use ToString to the Output window, you should see the UK format since ToString will use/respect the local culture setting of the computer.
Intellisense is culture agnostic and tries to use an unambiguous format: MM/dd/yyyy. This is the same "format" or order you have to use when creating a DateTime var from a literal:
Dim dt As DateTime = #1/5/2014# ' e.g. MM/dd/yyyy
' same as:
Dim dt As New DateTime(1, 5, 2014) ' mm, dd, yyyy
This is InvariantCulture (not US). When you hold the mouse over the var, the VB IDE will use the same order. It tries to make clear it is using the required literal/InvariantCulture format by displaying it with the hashes: #1/5/2014#.
Dim dt As DateTime = #2/11/2011#
Console.WriteLine(dt.ToString)
In the US, 2/11/2011 will display based on the culture
In the UK, it will be 11/2/2011
Intellisense will be #2/11/2011#

EntityFunction.TruncateTime not working in my query

I am using Linq to entityframework to query some infomration. I am trying to use entityfunction.truncatetime and it doesnt seem to work as expected. here is my sample query
From d In Request
Where d.Requestor= "XXXX" And d.ProcessedFlag = "N"
Select d.RequestID, RequestReason = d.RequestReason.ItemValue, RequestType = d.RequestType.ItemValue, RequestedDate = EntityFunctions.TruncateTime(d.RequestedMoveDate)
The requesteddate doesnt seem to truncate the time part and I am still getting the both Date and time.
Am I missing something here?
In .NET, the DateTime class actually represents both a date and a time. Internally, this is stored as a numeric value represented by the number of 100-nanosecond "ticks" since Midnight, January 1, 1001 AD. This number gets "converted" when it's displayed (either in output or in a debugger). This conversion is done via a format string.
Even if you truncate a DateTime's time portion, it still has a time... it's just 00:00:00, and if you don't want to see that time, you need to adjust your format string to not convert that.
Thus, if you do something like this: DateTime.Now.Date it will display `10/15/2012 00:00:00" if you use the default date conversion string (or whatever is the default format for your culture).
If you want to only display the Date portion, then you must do something like myDate.ToShortDateString() or myDate.ToString("d").
EntityFunctions is a set of tools designed to be used in Linq to Entities queries, because doing DateTime formatting is not normally allowed in a query.
For example, this code does not work:
var q = from x in dc where x.BirthDate == DateTime.Now.AddYears(-15).Date select x;
You have to do it like this:
var q = from x in dc
where x.Birthdate == EntityFunctions.TruncateTime(DateTime.Now.AddYears(-15))
select x;
This will then generate the correct SQL to do date comparisons in SQL code. This is what the EntityFunctions are designed for, not truncating dates in the select portion (although it does work). But, even though the date is truncated, it will still have a Time component, it will just be 00:00:00, and you must use a date format string to present it to your users in the manner you intend.
cant you use ToShortDateString() like below?
List<DateTime> time = new List<DateTime>();
time.Add(DateTime.Now);
var WhatDate = from date in time
select new { Date = date.ToShortDateString() };
In your case try this
From d In Request
Where d.Requestor= "XXXX" And d.ProcessedFlag = "N"
Select new{ RequestID = d.RequestID, RequestReason = d.RequestReason.ItemValue, RequestType = d.RequestType.ItemValue, RequestedDate = d.RequestedMoveDate.ToShortDateString()};

xml and condition by dateTime

Code
var elements = from element in doc.Descendants("CalendarFair")

select new
{
dateStart = element.Element("DateStart").Value,
dateEnd=element.Element("DateEnd").Value,

idExcutive = element.Element("IdExecutive").Value ,
};
foreach (var item in elements)//send this error
{}
System.FormatException: The string was not recognized as a valid DateTime. There is a
unknown word starting at index 0.
why error?
Try to change it as follows:
var elements = from element in doc.Descendants("CalendarFair")
let start = element.Element("DateStart").Value
where DateTime.Parse (start)==DateTime.Now.Date
select new
{
dateStart = start,
dateEnd=element.Element("DateEnd").Value,
title=element.Element("Title").Value,
idExcutive = element.Element("IdExecutive").Value ,
};
EDIT: based on the XML you have posted the query above works pretty well. Try to test it with this input:
<CalendarFairs>
<CalendarFair>
<DateStart>2011-04-05T00:00:00</DateStart>
<DateEnd>2011-04-09T00:00:00</DateEnd>
<Title>aaaa</Title>
<IdExecutive>1</IdExecutive>
</CalendarFair>
<CalendarFair>
<DateStart>2011-03-20T00:00:00</DateStart>
<DateEnd>2011-04-19T00:00:00</DateEnd>
<Title>bbb</Title>
<IdExecutive>2</IdExecutive>
</CalendarFair>
</CalendarFairs>
Note that I have inserted today's start date. Actually I think the result was empty just because there weren't entries with actual date.
It sounds like one or more of your input <DateStart> strings is not in a valid DateTime format.
Can you post some sample input XML?
It may be that you need to provide the date format using ParseExact - http://msdn.microsoft.com/en-us/library/w2sa9yss.aspx
