Hi,

Is it possible to trigger content assist a second time after the user has selected one of the choices?

For example I have created a scenario lilke the following

The user types a '<' and is presented with a list of HTML tags
The user selects a tag
I'd then like the auto assist to insert the tag name plus a space and then show a list of attributes to select from

I haven't been able to get this to work without making the user type that space themselves (eg. space have the space in getCompletionProposalAutoActivationCharacters)

So when I think I want is to autoactivate a second time on the user's selection. Is this possible?

Thank you,
Andrew.

I'm not sure how one would do that, but one thing you might try is sending the space key events to simulate the user having entered the space by calling org.eclipse.swt.widgets.Widget.notifyListeners(int, Event) with the appropriate SWT event code, e.g., KeyUp/KeyDown and the appropriate information in the Event, which is a bit tricky, so you might want to listen for these events and see what information exactly is in the event when the user actually enters a space.
