[udig-devel] Adding multiple layers using single resource

[Maria Comanescu]

Hi, 
Thanks Jesse for your answer. 

It worked for me using different schema names than sending CommitCommand. 
Also, thank you for your help with the "How to set 
focus on layer" issue.

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.
