Zhenchao,

this is a really annoying issue we were not able to get rid off. The reason of this is deeper inside the GEF and Draw2D coding and even in layers underneath. It was not possible to overcome this with official APIs thus fixing was not possible.

What we have introduced is a deprecated method in the tool behavior provider (getDiagramScrollingBehavior) that would allow to switch to a mode that will always show scrollbars, which is of couse only a workaround. Unfortunately it relies on rewriting internal functionality from the frameworks Graphiti uses. Therefore we cannot guarantee that this will continue to work in the futire as well and therefor we deprecated this functionality.

Other options to overcome this are as well not really nice, an idea would be to define some invisible shapes on the diagram and place them as far outside in the diagram so that they will enable the scrollbars and the context buttons can appear without creating them.

Sorry for not haveing a better answer,
Michael
