Always happens in this project when I pressed Publish (F5) in VS Code. Other projects works just fine.

Is it possible to debug the compiler?

[defr0std]

Compiler sources are not shipped publicly, so debugging would be problematic.
From the stack trace we can only see that this happens when reading information of a base app table from the symbol reference file (Microsoft_Application_xxx.app).

• Could you please let us know the what country version you are running?
• Do you have any dependencies on other extensions? ("dependencies" property in app.json)

[defr0std]

Could you please ensure that symbol files (Microsoft_*.app) in .alpackages folder for all your projects are exactly the same?

[DusMArio]

I have the same problem but am not sure what changes did I make to force it.

To solved I tried to delete the app files in .alpackages folder to force recreation, but it did not help. I don't have any dependences set in app.json and am working on W1.

[defr0std]

@DusMArio, are you working on the same project with @SShadowS who opened this issue?
If not, cleaning .alpackages will not help since this error is different.
Could you please let me know which AL extension version you have?

[DusMArio]

@denissfrostlander no I am not working on the same project but I found the reason for the error:

The order of properties set to a page is obviously important ('InsertAllowed', 'ModifyAllowed' must be set before 'SourceTableView' and of course 'SourceTable').

I had to move this line:

SourceTableView = SORTING("Guarantee No.","Line No.")
ORDER(Ascending);

after these lines:

InsertAllowed = false;
ModifyAllowed = false;

EDIT: The AL Language version is 0.12.15355

[defr0std]

@DusMArio, the order of properties should not actually matter. This is a bug, but it looks like it is already fixed in the latest internal codebase. I can reproduce it on an older extension version and not on the latest build.

@SShadowS, could you please let me know if it helps to recreate the .alpackages folder.

[qutreson]

@DusMArio, your problem is the same than #1303 which will be fixed in the next update.
For now, there is a work around if you declare the property SourceTableView under the other ones.

[qutreson]

Re-opening as the original issue from @SShadowS remains unsolved.

[thpeder]

@SShadowS if you still having the problem then please open a new issue for us so we can get it fixed.
