selectionChanged listener not getting called when view is minimized [message #556928]

Hi,

I have 2 RCP Views, one containing a JFace TreeViewer (Navigator View) and
the other containting a JFace TableViewer (Metadata View). Based on the
selection made in the tree in the Navigator View, the contents of my table
in the Metadata View should get refreshed. This is done by implementing the
selectionChanged listener in the Metadata View.

Now my problem is that if I progrmatically change the selection in my tree
while the Navigator View is in the minimized state, the selectionChanged
listener of the Metadata View does not get called and its contents do not
get refreshed. This, however, works fine if my Navigator View is not
minimized.

Does anyone have a solution to this? How can I ensure that the contents of
my Metadata View get refreshed even if the selection in the tree is changed
programatically while the Navigator View is minimized?

Thanks and regards,
Nikita

For anyone looking for the solution to this issue.

Let's say you have a ListViewer that you are using as your SelectionProvider but you aren't necessarily using your mouse to navigate and click the items. If you call listViewer.getList().select(SOME_NUMBER) then the SelectionChangedListener is not invoked. To fix this you must access the SelectionProvider by calling getSite().getSelectionProvider().setSelection(listViewer.getSelection()); within your active view.
