Hi Experts,

I have a problem related with a composite provider.

I have a composite provider with the union of 3 adso

In the same composite, a join of another adso.

Before making the join I am able to mark the flag "This Composite can be added to another CompositeProvider without problem but after the join the flag is disabled and I can not reuse it anymore.

Thanks in advance for your help.
