Thanks Steve for your suggestion but I don't think that will help. Even
than I would have to redraw all DataReferences in order to refresh the
Display. I would need a way to redraw only one DataReference instead of
all. I experimented with Display.disableAction(). So I can prevent the
display to render the data every time a change is done. But now I need a
method to explicitly render one DataReference or to prevent the other
DataReferences from rendering. I think something like
DataRenderer.disableAction() with different DataRenderers for the
different DataReferences would do the job. Unfortunately I could not
find such a method :( Perhaps overwriting the DataRenderer.doAction()
method would be a good idea?

Any other idea would be appreciated.

Cheers, Mathias
