I have 2 views in my application both of which get values to be populated from a single source.
When data is received from the source, event gets triggered on both views to get data pertaining to that specific view from the source and update the view.

One is a JFace TableView and other is Tree view.

Now, when both views are displayable at the same time in te eclipse application and data is sent at a fast rate both views try to pick the data and update its own view and the UI thread hangs.

How do we handle this scenario?

Hi Pandit.

Process in a separate thread. When it is time to update the UI then call

Display.syncExec(Runnable)

You can also process inside a Job. This will give the user some visual
feedback.

Best regards,

Wim
