Dynamic content in JList renderer

Question

Hi all
I've got a gui with a JList with rather complex content. I render that content with a custom ListCellRenderer that uses a JPanel. This works perfectly well for "non animated" things like text, JLabels etc.
Now I want to add to these panels in that JList a JProgressBar in "indeterminated" state (that is constantly sliding back and forth). The proglem is that the whole JList only does a repaint when the JList itself needs to do so (when resizing the window for example) and not when that Jprogressbar wants to repaint (in only gets rendered once)
Can I solve this, or will I have to implement my own JList-like panel.. That would mean I also have to implement the whole "selection" thing, which was why I choose JList in the first place.
thanks in advance

camickr suggested a way to solution. Notifying list of its contents change is the way to present change to the user, for example ProgressBar change. You could not to use Timer and instead notify your list immediately its item have changed.
For a perfomance you could not to re-create your Renderer instance for each item but save it and reuse. The renderer will be repainter either way.
