Eclipse content assist (JavaCompletionProposalComputer) not triggered

Question

I have a plugin that implements a content assist hook using JavaCompletionProposalComputer. Upon that event, I compute something and the update my view. The problems is that the view stays on and I am not able to trigger content assist and thus my handlers. When I minimize the view, I am able to use it again normally. Is this some kind of focus problem? How to solve this? Any help appreciated.

Answer 1

it seems that my problem was related to focus. For some reason, the focus was lost whenever I "showed" a view. I resolved the issue by replacing

IWorkbenchPage.showView(view_id)

with

IWorkbenchPage.bringToTop(view)

Hope somebody will find this useful.
