I'm looking at a constraint error when running this code. In the debugger it halts on the 2nd line (Menu_Text...). I put the code on the RHS of the assignment into the watch window and I see no problem. It's evaluates exactly as it should.
for I in 1..This_Info_Ptr.Child_Menu_Length loop
Menu_Text := This_Info_Ptr.Child_Menu_Text_Ptr.all(I-1);
Menu_State := This_Info_Ptr.Child_Menu_States_Ptr.all(I-1);
...
The error is when I is 1. I have confirmed that this code works in the watch window:
This_Info_Ptr.Child_Menu_Text_Ptr.all(I-1)
Child_Menu_Text_Ptr and Child_Menu_States_Ptr point to arrays (of strings and enums),
How should I debug this I general? I can't see anything wrong with the code. However, my familiarity with Ada access types is limited. The ..._Ptr variables are access types.
I am using GNAT.
Assuming the arrays being indexed are all of the same dimension and have the same index type, then iterating over them should be done using the 'first & 'last or 'range attributes.
It is likely that the hand coded control of length values has a bug.
Using the inbuilt functionality is safer and more reliable.
You aren't showing enough source text to tell us for sure what is happening. IsThis_Info_Ptr.Child_Menu_Text_Ptr.all a function or an array? What is it's specification?
If it is an array, you should remember that Ada allows arrays to be indexed by any discrete type, and that arrays in Ada always know their own indexing bounds.

Right or wrong: In Cypress, its impossible to read a value on page X, then keep this value and compare it to a value on page Y.
I can read a value from the page and log it:
cy.get('[data-e2e-selector=whatever]').then(elm => cy.log('Value from page X : ' + elm))
or, for instance, the number of elements with similar or partially matchin selectors:
cy.get('[data-e2e-selector=^whatever]').then(elm => cy.log('Number of elements like this on page X: ' + elm.length))
Hoever, I cannot create a variable of this, because of the asynchronous way Cypress runs. Right? Any value created to just be blank.
Nor can I pass the value read to a method, which in turn compares it to the value on the next page:
compareToValueOnNextPage(cy.get('[data-e2e-selector=^whatever]').then(elm => elm.length));
compareToValueOnNextPage(value: number) { // NB: Not sure if it's a number or string yet...
cy.get('[data-e2e-selector=^whateverNextPage]').then(elm => elm.length).should('have.length', 4)
}
Basically, if I want to compare values, the either have to be on the same page, or they need to be hard-coded. This is a huge limitation when actually end-to-end testing some applications. Very often, a value is created on page X, based on input which should in many cases ba random, thus creating a dynamic value in the test. Then, on page Y, that same value is fetch (from the backend) or shown in some other way, in a Summary etc. And, naturally, I want to compare the value shown on page X to the one shown on page Y/Summary. But this is not possible, due to the very unit-testing thinking that seems to be the foundation for Cypress.
Or am I missing something here? Are there ways around this that aren't ugly/smelly? I think it's possible to store the value on page X in a file, then read that file on page Y. However, Cypress seems to only have one option when reading the file, and that's reading the whole file and looking for a match. So that file would be a mess. Or I'd need several files.
I realize this is kind of trying to impose non-functional ways on a quite functional and asynchroeous technology. However, if it's not possible to "keep" a value and use it later, it's very limiting when it comes to end-to-end testing (even though it's not when the testing is unit-based on frontend components).
UPDATE:
As per Kerrry's suggestion in the answer below:
cy.get('[data-e2e-selector=dellan-accordion]')
.then(elm => cy.wrap(elm.length).as("myVariableName"));
-GO TO NEXT PAGE-
cy.get('[data-e2e-selector=betalingsplan-dellan]')
.then(elm => elm.length)
.should('have.length', myVariableName)
This yeilds "expected 4 to have property 'length'.
This means, obviously, that I cannot get the length of the length.
So I replace 'have.length' with 'eq':
cy.get('[data-e2e-selector=betalingsplan-dellan]')
.then(elm => elm.length)
.should('have.length', myVariableName)
And I get the following error:
expected 4 to equal 0
So, it seems that the first variable - myVariable - is gone after the first cy.get().
If I do everything inside one get (have another get inside that, where I go to the next page AND get the count of the elements), then it works. But the way Kerry shows it, it would be much more flexible. But, alas, the above error.
As jonrsharpe mentioned in the comments, please read the Cypress document on variables and aliases thoroughly. This is a core concept of Cypress, and it will give you a solid understanding of how to implement variables and carry the values between test steps.
The reader's digest example of what you how you can achieve is this:
cy.get('[data-e2e-selector=^whatever]')
.then(elm => cy.wrap(elm.length).as("myVariableName"));
What this is doing is cy.wrap will yield the value from elm.length in a Cypress command chain, which then allows you to assign it to an alias "myVariableName".
In your following test step where you want to compare the value on a separate page, you would then access the alias' value in one of two ways:
Using this.
cy.get('[data-e2e-selector=^whateverNextPage]')
.then(elm => elm.length)
.should('have.length', this.myVariableName)
OR
via cy.get()
cy.get("#myVariableName").then(function(variableValue){
cy.get('[data-e2e-selector=^whateverNextPage]')
.then(elm => elm.length)
.should('have.length', variableValue)
})
I changed Change in persistence.xml
I also changed column definition (columnDefinition="XDB.XMLType") for xml fields
I checked OpenJpa(http://openjpa.208410.n2.nabble.com/Oracle-XMLType-fetch-problems-td6208344.html) site and IBM (http://www.ibm.com/support/knowledgecenter/SS7J6S_7.5.0/com.ibm.wsadapters.jca.jdbc.doc/env/doc/rjdb_problemsolutions.html)
My env is OpenJpa 2.0 and WAS 7
its throwing exception
org.apache.openjpa.persistence.PersistenceException: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "SYS.XMLTYPE", line 169
Please suggest without changing OpenJpa2.0 as its part of IBM WebSphere Application Server V7.0 how can i handle sys.XMLTYPE data, i am migrating my application from db2 to Oracle in same environment.
Writing XML data can be tricky some times! Getting the correct drivers and things defined properly can have its challenges. I can not say exactly what you need to do given the lack of info on your domain model and such, but let me give some general things to look for. First, there is an XML test in the OpenJPA test framework if you want to make reference to it. It can be seen publicly here:
https://apache.googlesource.com/openjpa/+/refs/heads/trunk/openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/jdbc/oracle/
Or, another test using an "XMLValueHandler" (likely this is beyond the scope of what you are looking for):
https://apache.googlesource.com/openjpa/+/refs/heads/trunk/openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/persistence/xmlmapping/query/
Second, (stating the obvious) I assume you have a column in Oracle defined as "XMLTYPE". Also, I see you are using schema SYS. I'm sure you are aware but this is a system/admin schema......just for sanity sake you might want to first get things running using a non-system/admin schema just so we don't get hung up with any issues with your OpenJPA client not having the correct permissions.
Next, you need the following definition:
#Lob #Basic
#Column(name = "ANXMLCOLUMN", columnDefinition="XMLCOLUMN XMLType")
private String anXMLString;
The #Lob I think will be necessary if you are using data greater than 4000 chars (this was mentioned in one of the comments). To start I'd use a very small set of data (a couple characters), once that works, then experiment with > 4k.
Next, make sure to use the correct JDBC driver. The last time I experimented with an XMLType I used the Oracle JDBC 11.2.0.2 driver.
Finally, you might need to use the property "openjpa.jdbc.DBDictionary" with value "oracle(supportsSetClob=true,maxEmbeddedClobSize=-1)". Again, experiment with this AND look at the OpenJPA documentation on these properties to determine if they are necessary in your scenario. I think the supportsSetClob=true will only be necessary for older version (pre-2.2.x) of OpenJPA. You might also need to use property "openjpa.jdbc.SchemaFactory" with value "native". I would suggest you first try without either or these two properties. If that doesn't help, then experiment with these two properties. I know this is vague, but I don't know what your DDL or domain model looks like so I have to keep in vague.

My intention is to somehow clean source files automatically. How to do that in XQuery? (I am not interested in reconstructing the document in memory and storing it as a new one.) It is quite easy to do something similar in case of short and simple elements addressed directly, however, I can’t figure out how to do that dynamically for all the text nodes, if possible.
I would expect something like this could work:
update replace $div[contains(., 'chapter')] with replace(., 'chapter', 'Chapter')
This throws err:XPDY0002 Undefined context sequence for 'self::node()' [source: String]
Apparently, there is a problem in addressing the context with . in the replacing function. But maybe I don’t understand the update thing in general. I am only inspired by the bottom of this article.
Expression to the right of with is independent from expression to the left. So an explicit node/context is needed on both part :
update replace $div[contains(., 'chapter')] with replace($div, 'chapter', 'Chapter')
I am trying to write a procedure that given a memory address and data type, will display the value of the data at that memory location.
I'm thinking that the best way to do this would be to use the To_Pointer function in the generic package Address_To_Access_Conversions, but every time I try to use it I get an error:
invalid prefix in selected component "Address_To_Access_Conversions"
I've ben unable to find any examples of how the Address_To_Access_Conversions is actually used. And I may be on the totally wrong track.
Does anyone know how to use the above package to convert an Address to an Access type and more importantly, a good way to access data at a given address to display to console?
Edit
The solution I found most in my research was to use something like the following:
for X'Address use dummy_address;
The only problem was that at that point in the code, I hadn't calculated what the dummy address was and that statement would only work at declaration, before 'begin' I found a way around this though with block programming:
dummy_address := base_address + offset;
Dummy_String:
declare
subtype Xdummy is Integer;
S : Xdummy;
for S'Address use dummy_address;
begin
--More code here
end Dummy_String;
I created a new table and added a new Integer field (called RefTableId) with an EDT of the standard RefTableId type. Writing NewTable.RefTableId = tableNum(SomeTable); compiles but during run time I get this stack trace error: "Error executing code: Wrong argument types in variable assignment."
I've even tried NewTable.RefTableId = 0; This still fails. And yes, I've triple checked that it is indeed an integer field.
The solution is really stupid, the line before the assignments was reading .data() out of a FormListItem object that had invalid data in it. Instead of showing an error for that line, it skips over it and fails the assignment lines below. It makes no sense to me since I wasn't using any information from that FormListItem object to populate any field data with, yet still caused that to fail for some reason. I'm going to mark this one in the "Bang Head Here" category.
If the code is in a class, be sure to do a compile of all super classes as well as a compile forward (child classes). Remember to do an incremental CIL.
If it still fails do a full compile (axbuild).
