Hi Folks,
I'm currently using a CheckboxTableViewer with an IObserverable List that populates the table with items.
The issue I am having is that once a new item is successfully added to the IObservableList the display of the table does not get updated UNLESS I click on the display somewhere (on the scroll bar, anywhere on the display in the web browser, etc.).
I was wondering if it was possible to update the display without having to constantly click something.
Any help would be great.

Peter,
What you are looking for is the UICallback. See the FAQ entry here[1]. Keep in mind that the UICallback must be activated from the display thread. Also remember that you can/will have multiple clients connected, each with their own display and their own databinding realm. I think you would need each viewer to have its own IObservableList and only update that list from its display thread using asyncExec(). If there is a shared data model, then you would need to have each client register a listener which holds a reference to its Display that it can use to call asyncExec() which notified of a change to the model. Then, of course, be sure to cleanup all of the listeners when the display/viewer is disposed.

Hope that helps,
Cole
