Problem with branching and merging models in Framework manager

[backhandx]

Hi all,
I'm trying to understand merging in Framework manager but there is a thing I didn't understand how it works.
I will give an exemple to explain the situation.
Let's assume I have a root model named A and from it I branch a second model named B.
I suppose I have a subject query named C in A and obviously in B models. C contains a data item named (a).

Suppose there are modifications in the A and B models as following:
we add a dataitem (b) in the C query item on the A model. And we add c dataitem to the C query item on the A model B:

A: model                 B model
   C : Dataitem           C: data item               
   a                             a
   b                             c

When merging B into A I expect to get the C queryitem as : C(a,b,c). But in reality I get this result C(a,c).
Can anyone explain me please why this occur this way. And how can I merge without overriding the data added to the root models after branching?

Thanks in advance.

Hi, when you create a query item make sure you change the design name by going to second tab in properties of query item where you see language specific values for properties like name, description etc. If the name is left as default both b in project A and c in Project B are treated as same object and FM will overwrite the object properties and the expression.

Thanks
