Okay... think it's only prudent that I add the solutions I've come across so
far.
First of all... I stopped using an AreaShapeLayer and started using an
EsriLayer. That made things much easier in terms of the dbf file access. I
was able to call getModel() on the EsriLayer and then loop over the rows. No
NPE's there.
I have a new problem however.... I need to label the shp layer. Apparently I
can't use the .rule property to get it labelled??? How do I label the
attributes in the shp layer or must I add my own text objects?
