[sapphire-dev] refresh content assist

[Ling Hao <ling.hao@xxxxxxxxxx>]

In the migration guide,

element.notifyPropertyChangeListeners( property ); 

should be replaced with:

element.refresh( property );

This migration broke the my custom content assist which extends PropertyEditorAssistContributor. The original call refreshed the content assist.
How can I programmatically refresh the content assist?

Thanks,
Ling
