Re: [udig-devel] change new feature

[Piebe de Vries <piebe.de.vries@xxxxxxxxx>]

An additional problem is that when  the Create Rectangle Tool is used 
instead of the Create Polygon Tool the following error is thrown.
It seems I really need another way to access newly added features.

This is the code:
private String getEffectTypeId() {
               Display display = getSite().getShell().getDisplay();

               // Create the parent shell for the dialog, but don't show it
               Shell shell = new Shell(display);   
//<----------------------------------- invalid thread acces (but no 
problem if create polygone tool is used :(   )
