I am using latest version of FullCalendar with their schedule plugin. I can't find how to get all empty slots in an array using DayAgenda view. I am trying to pass an empty object to the empty time slots. I have searched through their documents but couldn't find anything.

Fullcalendar.io getEvent by date, or by extended property

Is there a way to find all recently-added events in the local memory using the default object property names, extended properties, or events on a specific date?
calendar.getEvents() gets everything calendar.getEventById() gets only specific IDs. Is it my job to filter that returned array?
Is it better to add user-created events to a different Event Source.... and use THAT source when constructing an object for the server?
How do I find all newly created events added by the user? And, how do I get all events for a specific date?

What is the syntax to add a column to the Custom Form list that shows where in WF it is used?

Super simple.
When viewing the list of Custom Forms in Setup, I want to add a column that shows where those Custom Forms are in use (or null if used nowhere).
This is similar in principle to viewing the list of fields, which has a list of forms on which those fields are used.
What is the syntax I can use to add the appropriate column(s) to the view?
As far as I know, there is no linkage in the backend that connects categories (custom forms) to their host objects. This is probably because the list could be massive and the query would take quite a while to execute as it would have to traverse every object in Workfront or each form would store every parent object ID.
Unfortunately, you can't even search for objects by associated category IDs, so if you wanted to build this yourself you would need to query each object and search its categories to see if your custom form appeared.

Displaying data in a datagrid in an Alfresco task form

I have a json array variable defined in my activity workflow definition. Now, I need to present the data of the json array in a datagrid inside a form task. One of those columns should be a check entry filed so that the user may select some rows. After that, I need to get back that data in a subsequent form task (so I need the data to be updated in the json variable so I can read it back, mainly the user selected checks).
Any example to accomplish this? I didnt find almos nothing relating with using datagrids in Alfresco task forms.
thank you!

When passing an ObservableCollection using MVVM Light's messaging, is a copy passed or is a reference passed?

We're working on a new WPF app, using MVVM Light. We've got a customized ObservableCollection which starts as being bound to a datagrid. According to the project's specification we have to start on a form showing the datagrid and then when a user selects a row we show the user a detail view in another form. At this point we're getting the selected row and assigning that to an object which we assign to a MVVM Light message so that the detail view will be able to display the record's details.
Now that we're getting into this we've encountered a complication. The specs require that the detail view be able to navigate through the collection, even though at this point it doesn't have the collection. We had through we could accomplish this through an interface we defined that we called IRecordService, implementing it for each type of record we work with. However the problem is that the record has no idea if its the first record in the collection, the last one, etc. And that's necessary because of buttons on the detail form where people can navigate through the collection. We've been trying to do this with, for example CustomerRecordService, but so far that hasn't worked out. Perhaps it will if we keep at it.
But I've been wondering, what if instead of creating an object that has the selected record in it which gets passed into a message, we instead pass the whole collection and the key to the selected record into the message which then is caught by the detail viewmodel? My co-workers primary concern is how is the ObservableCollection passed, under these circumstances? Is a copy of the ObservableCollection passed or a reference to theObservableCollection that's in the listing viewmodel? I would think its a reference, but wanted to ask to make sure I'm right, or not.
It has to be just a reference. Otherwise messenger would have to know how to clone every single object. But you can easilly check it. After you get an object in your details viewmodel, change it. Add something, remove something and change some parameter of some objects in the collection. Then check if it has been changed in the main form with the grid.

Can you create a joined view from task list and related content?

I'm trying to create a view of approval tasks that also includes a column from the related form library. I have tried creating a linked data source between the tasks list and the form library, but have trouble finding much information on creating linked views with the task list.
I have tried:
http://deannaschneider.wordpress.com/2012/07/25/joining-the-task-list-with-related-content-in-a-dvwp/
without luck - it just tells me "there are no items to show in this view." which I assume means it couldn't be joined correctly with the specified table.
I am using the standard approval workflow.
Here is the closest solution I've found so far
1.) Create task form fields in SharePoint designer.
2.) Go into Approval(1) to add the task form fields.
3.) Click 'Change the behavior of a single task'. Add 'Set task field' action in the Before a task is assigned section to set the task form fields to get the value of Current Item:ID.
4.) Use the new task field to create your subview on your linked datasource
While not optimal - and it created me many different problems - I was able to create the view desired.
Hopefully someone will come up with a better solution.
