Hi Thomas,
Thanks for your patience.
I wasn't clear about the "undefined": it is not a regular trace() line
(which show up in black in the Console), it is the word "undefined" in
RED and it shows up as the top line of the stack trace dump after the
crash, like this:
<Console output>
SWF] Presenter_AIR.swf - 2,508,088 bytes after decompression
undefined
at
nl.ixms.app.data::SheetItem/loadFromDbResultHandler()[/{removed}/SheetIt\
em.as:114]
at nl.ixms.db::Db/dbResultHandler()[/{removed}/Db.as:214]
at flash.data::SQLStatement/internalExecute()
at flash.data::SQLStatement/execute()
etc.
</Console output>
