I only explicitly set the selectedRecordA in two places, during the
cancel and add onSubmit methods (I removed the initialization in the
declaration in my code). As you alluded to earlier, add is done via
setSelectedRecordA(new RecordA());
and cancel is done via:
RecordAPanel.this.selectedRecordA = null;
I changed cancel to be:
setSelectedRecordA(new RecordA());
but it doesn't seem to make a difference, still get the issue when
cancelling.
Should I be setting the selectedRecordA to null on cancel? It makes
sense to me and it's what I've done in other applications/frameworks,
but perhaps it's not correct in Wicket...

Think I was going in the wrong direction.. Looking at the error, seems
to
get triggered by pressing the cancel button only..
