Problem extending JUTableBinding

Question

I tried to extend the JUTableBinding to expand the functionallity of the getValueAt()-method from the inner JUTableModel class. In doing so i encountered the problem that i can't extend the JUTableModel inner-class correctly cos its constructur is only package visible. But this should be possible imo as the javadoc of JUTableBinding states it. Is there another way realizing this?

Hello,
the sample given shows how to set up a sorting model on top of the existing Table model. In opposition to this i want to overwrite existing methods from the JUTableModel of the JUTableBinding, as there are getValueAt() and setValueAt(). Imo this has to be done via extending the JUTableBinding and its inner-class JUTableModel. This way of doing is also written down in the javadoc of the JUTableBinding:
* Applications should subclass this binding and return a subclass of
* JUTableModel that can:
* <ul>
* <li>Perform application-specific sorting of rows displayed in a JTable.</li>
* <li>Dynamically display/hide certain columns based on user preferences or application logic.</li>
This leads to my still unsolved problem, cos i can't extend the JUTableModel inner-class correctly cos its constructur is only package visible.
Is there an other way doing this, or is the visibility set wrong in JUTableModel?Javadoc is wrong as you cannot subclass an inner class.
You should be able to "override" get/setValueAt for the model behind a JTable with the earlier approach defined in the other thread regarding sorting model. Simply implement get/setValueAt in the "filtering" model and delgate the rest to the inner JUTableModel.
