Problem with Dynpro-models & RFC-modules

We are using the possibilty to let a WebDynpro-controler call a remote RFC module. We have are own namespace '/CIVBS/' for defining our modules and now we encouter a problem that the '/' is translated into a '_-' with a negative result that modules with this namespace are not found.

We are using Beta II of the Netweaver Developer Studio.

Can anybody give a hint ?

regards
