How to handle AutoComplete control properly in Grid Cell Editor? [message #63905]

Dear All,

I encountered a mouse focus issue with AutoComplete control.

First I extended TextCellEditor to provide auto-complete feature via:

a. IContentProposalProvider
b. ContentProposalAdapter

It works great with keyboard navigation. But, when I mouse click a popup
proposal, the floating information control gets focused and TextCellEditor
loses focus. Then the selection won't change the editing text.

Do I need to register additional listener to some control? If yes, what's
it?

Thank you so much for the help! It not big issue but bothers a lot.

Best Regards,
Frank Du

The problem is how JFace handles this scenario. Please use the code
shown in
