[udig-devel] Adding multiple layers using single resource

[Jesse Eichar]

I think the reason is probably because there is a bug in  
createTemporaryResource where the FeatureTypeName must be different  
for each layer otherwise it may return two resources backed by the  
same FeatureStore.  I suspect that if you commit then you will see  
that both layers have all the features.  Although I could be wrong.

Try by changing the schema name.

Remember that to change a name you have to create a new featuretype  
with a new name.  SimpleFeatureTypeBuilder should make this easy.
