Not sure of the precondition, the error is not always thrown. Error message: "Error reading No associated Tableau! Can't open a file." Stack trace: java.lang.Exception: No associated Tableau!

Not able to reproduce anymore, assuming this is fixed.

I agree that this is not reproducible, so I'm changing it to "Resolved" -> "Worksforme".

I took a quick look at this and it looks like the error is thrown if the _tableau in TableauFrame is null. One way to set _tableau to null is from the TableauFrame constructor. Another way is that TableauFrame.setTableau() could be called with a null argument. TableauFrame.dispose() calls setTableau(null).

The only way I can see this happening is if there is a TableauFrame that somehow has a null _tableau, either by construction or by calling dispose().

Anyway, this seems unlikely, and as we have not had other reports of this problem, closing it is the correct thing to do.
