[SOLVED] Can't attached version to component - by: ashofphoenix

Hi,
Here is my problem using V7.0.9
I create a Component A and create a version for it
I create another component B and create also a version for it

Looking at my components, I've got the version properly set.

Then I said that B component is a Component "used by" A component.
Then I click on my A component.. B component is properly show as "component used...".
Now I click on my A component version specification to "attached" the proper version of B component to this specific Version of A and then click on "list of component version used by this version" and I select the version of my B component and press "select element".

Here I always as the same problem, saying "invalid control / This like already exist .
Knowing that I never attached component B version to Component A version, I don't know HOW this link could already exist.. By the way, if it exists, it is not shown on the component A version sheet...

Where does it go wrong... ?? right now I can't manage to attached "version to version" which is a big pb

Thanks for your help

Regards
