Hi folks,
I've been asked to post this message here after discussion on the intermediate forum, you can check out the other post
here. My table model is from a class which extends AbstractTableModel.
The error occurs every time the following sequence of actions is taken..
Double click in a cell (to put it in editing mode) then without changing the value, moving to another cell.
OR
Checking or unchecking the boolean checkbox generates the same error
Does anyone have any ideas what could be causing this? I've tried tracing it through the Eclipse debugger but it seems to occur in the Sun classes and I can't follow it once it leaves my code.
Thank-you, and sorry for the cross post.
