Hi there,
I'm working on a small RCP-Application. This application consists of a
tree view containing three different types of data, and a stack of three
views, each one linked to one of these data types. The views in the
stack implement the SelectionListener, so each time an item from the
tree is selected, the corresponding view loads its information. What I
now would like to do, is switching the view corresponding to the data
type when I select an item in the tree. I tried doing so by using
getSite().getPage().showView(viewId);
using the ids of the views, but, besides getting an Exception, it
doesn't seem to work as I hoped.
Does anyone know of a better approach?
Thanks
Robert

I get a RuntimeException:
java.lang.RuntimeException: WARNING: Prevented recursive attempt to

The problem appears to be connected to the tree view, from which I
select the different data types. The selectionChanged method I have
implemented in all three views appears to be called twice each time I
select a different data type, once from the old view currently active,
and once from the new view.

All views are activated, I just want to switch the visibility.

That did the trick, the views are now switching as intende.

Thanks a lot for your help, Paul!
