Hi there,
i want to completely refresh an outlinepage and the only way that i have
found so far, is to dispose the object and readd it. So i dispose the
object, remove all listeners (the outline part becomes gray) and then
re-add it. But the part of the window, where the new outline should be
displayed, stays gray. If i now click in this gray area, i get the
message "An error has occurred when activating this view".
My code for removal and re-adding looks like this:
Method, that initiates the whole procedure:
*******************
getActionRegistry().removeAction(outlinePageAction);
removeContentOutlinePage();
outlinePageAction = new ShowActivityAction(this, getContentOutlinePage());
getActionRegistry().registerAction(outlinePageAction);
********************
removeContentOutlinePage():
***************************
if (outlinePage != null)
{
((ModelContentOutlinePage)
outlinePage).getContextMenuManager().removeMenuListener(getC ontextMenuProvider());
getSelectionSynchronizer().removeSelectionProvider(outlinePa ge);
outlinePage.dispose();
outlinePage = null;
}
***************************
getContentOutlinePage():
***************************
if (outlinePage == null)
{
outlinePage = new ModelContentOutlinePage(this);
getSelectionSynchronizer().addSelectionProvider(outlinePage) ;
((ModelContentOutlinePage) outlinePage).getContextMenuManager()
.addMenuListener(getContextMenuProvider());
}
return outlinePage;
***************************
Thanks for help!

Hi Paul,
