[Solved] com.sun.star.lang.WrappedTargetException

[owlbrudder]

I have moved a dialog from the code module associated with a document, into a library I am creating. It used to work fine, but now calling it from my document module throws:

Code: Select all

Error 1: An exception occurred 
Type: com.sun.star.lang.WrappedTargetException
Message: 
TargetException:
  Type: com.sun.star.script.LibraryNotLoadedException
  Message: .

The dialog is in the library basPrinting and the library code can be run successfully independently, but fails when I call it from a module external to the library.

Here is my library code:

Code: Select all

ShowListPrinters
...
	dlgThis = CreateUnoDialog(DialogLibraries.basPrinting.dlgListPrinters)
...

and this is how I call it:

Code: Select all

	if Not Globalscope.BasicLibraries.isLibraryLoaded("basPrinting") Then
		Globalscope.BasicLibraries.loadLibrary("basPrinting")
	End If

		Dim strPrinter As String
		Dim boolGoodPrinter As Boolean
		
		boolGoodPrinter = False
		
		While boolGoodPrinter = False
			strPrinter = ShowListPrinters
...

It must be something to do with the external call, but all my other external calls to the library, none of which need dialogs, work fine.

Any ideas would be very welcome.

Kind regards,
Doug

I moved the dialog out of the library and back to my module. Didn't work. Moved the dialog from the module back to the library. Now it's working fine.

I HATE TRANSIENT BUGS!

NOT fixed.

1. If I exit LO then restart my application, I always get the WrappedTargetException.

2. If I either a) run the dialog directly from the library, or b) move the dialog from the library to the module then back to the library, everything works fine.

Thus, I can only use the application if I intervene in some way, which is sub-optimal.

Any suggestions?

Fixed by executing Globalscope.DialogLibraries.loadLibrary("basPrinting") prior to attempting to use it; in other words, I had loaded the Basic library but not the Dialog library.
