Re: Drawing tool problem

Hi Bart,

It's not a stupid question, it's a problem with how the
OMDrawingToolLauncher is implemented and how it expects to be added to
a MapHandler. It doesn't get information from the OMDrawingTool about
what loaders are available, it expects to gather it's own information
from the MapHandler on its own. There isn't a way to add laoders to it
directly, either.

If you create a MapHandler, and just add everything to it, everything
will hook up normally. The OMDrawingToolLauncher should be changed,
though, to work as expected - getting the list of loaders from the
OMDrawingTool.
