I'm loading two shape files;
one has 40 polygons,
one has 3000 polygons.
I'm want to group them once loaded and save the groupings and would like to avoid the long processing times to convert the shape files to layers.
My problem is my attempts to recall the saved layers keep blowing up world wind.
Tried Serializable/ObjectOutputStream, got (PreRenderable) renderable cast fail (I think).
Tried XStream, got JVM crash, EXCEPTION_ACCESS_VIOLATION
Anyone have experience saving/loading layers?
