Business rules for more then one domain based

Hello members, 

I'm stucked with this problem and i hope on a solution.

I got an entity that has two domain based to other two entities.

I created the first business rule with the first domain based and it works perfect.

But when i try to create a second business rule with the second domain based, and error appears:

200095 : Cannot specify more than one entity in MetadataGet 
• 400003 : The attribute reference is not valid. The attribute was not found. 
• 400003 : The attribute reference is not valid. The attribute was not found.

Obiusly the attribute is valid. Infact if i delete the first business rules, the second one is published correctly.

"Cannot specify more than one entity in MetadataGet"

I think that MDS block a second business rules if you try to apply to a second domain based attribute.

Do you know how to fix this? Is there any way to do it?

Thank you for your time,

Enrico
