The excel export is continuable, as long as the file dialog handler has not been cancelled. Once the dialog was cancelled, the following error message is thrown:
!STACK 0
java.lang.NullPointerException

I'm using the actual software released on Eclipse.org.
Looking at bugzilla, this bug was reported on May '12:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=379923 but never solved.
Ciao,
Michi

Hi Edwin, thanks!
Do you have a patch of the fix or a fast instruction to solve the bug?
In addition I noticed another errorneous behavior on export. Running the export a second time, an empty excel sheet is saved and the following exception is thrown:
java.lang.IllegalArgumentException: This Style does not belong to the supplied Workbook. Are you trying to assign a style from one workbook to the cell of a differnt workbook?
