Master/slave problem [message #755279]

I have view A with a tree viewer and view B with a table viewer.
The tree viewer has 2 levels; on the second levels it list the children(s) on first level. In the same time when a entry of first level is selected in the tree viewer the table viewer from view B is populated with entries. This works correctly so far.

Problem:
When I added support in table viewer for editing support, allowing the user to change the table values I do not see the tree viewer automatically updated.

Question(s):
1. Is there an automated mechanism to signal back to the tree viewer that it needs to be refreshed/updated?

Time is what you make of it.

See my answer to your other question. You have to call viewer.update(o,null)

The other option is to use Eclipse Databindings Viewer Support.

Hello Tom

I have 2 viewers in 2 separate views. In my EditingSupport setValue() method I do call viewer.update(o, null);, but this has effect only on the second view (the details view). The first view (the master view) is not refreshed at all.

As far as I saw Eclipse Databindings Viewer Support is effective only when a single view is involved and not two views. Do you have some kind of snippet for this case?

Time is what you make of it.

No when using SWT-Databinding and both Views show the same underlying
Object they would be updated both!
