[news.eclipse.technology.albireo] How to update a SwingControl

[jmananki@xxxxxxx (Julien M.)]

Hi all,

This must be a very easy thing to do but I can't get my SwingControl to 
update it's content (a JTree) the content (DefaultMutableTreeNode) of the 
tree change when receiving certain events, I tried 

swingControl.update;
parent.getDisplay().update();

but nothing happens.

Any idea what I should do ?
