Jesse and others,
I'm working on getting a basic rcp app without all the udig views/menus
working with a mapview (something like a mapeditor minus all the
mapeditor stuff... so basically a view that renders a map without the
extras). You can run what I have now from the rcp.product in
net.refractions.udig.tutorials.rcp.
If you run this and then click the "+" button on the view it will open a
MapView from net.refractions.udig.project.widget.view. Next click the
"down arrow" to load a shapefile onto the map. You will notice that
clicking to refresh the map or zoom to map work fine at this point. But
as soon as you resize the map viewport (which triggers a
layer.getBounds) it does not refresh properly (sometimes you will need 2
shapefiles loaded to see this problem). At this point, looking in the
debugger and pausing the threads to see what they are doing, I can see
there is a reentrant lock on the shapefile (in ShpFiles.acquireRead in
geotools) that never gains access. From this point on, any refreshes or
anything will never redraw that layer because the file is stuck locked.
This problem doesn't seem to occur in uDig with a regular MapEditor.
I'm unsure why the RCP app has the problem (I'm wondering if there is
some timing/rendering issue that may cause this lock problem). Jesse,
since you are the maintainer of shapefile stuff, and the render guru,
I'm wondering if you have any ideas? If you have any tips I would
greatly appreciate it, thanks!
