We have a multipage editor with a gef graphical viewer on each page. For
any given page, parent figures that are drawn (by DND from the palette) are
expandable. When one of these parent figures is expanded, children
(figures) are added to the parent figure. At this point, the selection
mechanism within the figure stops responding, though the workbench is still
alive and the max/min funcitonality of the figure still responds.
Additionally, adjacent figures, whether expanded or not cannot be selected
with any consistency. At times and after some time has elapsed, the
selection mechanism returns or awakens, at other times, it never returns
unless some random sequence of selection events triggers a "release."
These selection events do not get propogated across the platform to other
Selection listeners (in other workbench parts). We've tried to identify
embedded runnables, etc. but have not found any culprits(yet) so we are
questioning the listener implementation for our editor, the possibility of a
bug when using GEF with Multipage editors.
Has anyone seen this behavior or are there specific guidelines that are
being overlooked as it seems that this should be pretty straightforward
behavior?
Enclosed is a screenshot.
