Array IndexOutOfBounds Exception

Hello,
i do an application for a chess player association. In an internal frame, I have put a master JTable (Tournament) that list all the Tournament and a Detail JTable (Category) that lists the categories. (a tournament can have 1 or more categories). I have generated the entity classes. I have bind the master JTable and tournaments are listed as expected to, so it's ok. However, I have bind the Detail JTable in a way that it list the categories (in the Detail JTable) of the tournament selected in the Master JTable. I got this error :

I understand the signification of the error, but I don't understand why it does that?

The binding expression of my Detail JTable is ${selectedElement.classetournoiCollection}

Is selectedElement empty?

I would like to have some help.

Thanks!

That isn't Java. Whatever is it?

db

Is that... Javascript/ using Jquery?

Finally, we made it done with a hancoded sql query instead of binding via the Netbeans GUI Interface.

Since this was apparently related to some feature of the NetBeans IDE, I'm moving it out of New to Java.
