Java JList Update Using BeanBinding Netbeans

Question

I have this JList (say MyList) in a JFrame. I am using Netbeans6 GUI builder and I have set the binding for this list.

At startup, the binding works fine, and MyList populates correctly.

Now what I'm looking for is a way to add more data to this list from another text box when I click a button. But the problem exists here:

Binding w / o I would retrieve the ListModel for the JList using the function "getModel ()" and add an element to it using "addElement ()".

However, when im uses binding. and I try to extract the ListModel and map it to DefaultListModel, I get the following exception:

Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: org.jdesktop.swingbinding.JListBinding$BindingListModel cannot be cast to javax.swing.DefaultListModel

So my question is: how to add more elements to MyList that are already bound to another data source?

Does anyone have any clues? Any help would be greatly appreciated!

Thanks!

You need to change the list to which the JList is bound. And this list should be a list of changes observed for recording. The anchor point is that you no longer manipulate component models, but instead subtopics.
