NB 6.1: Can't add cyclic references

Hi,
I have an enterprise application (let's call it EntApp) consisting of
two EJB modules (ModuleA and ModuleB). Now, I want to do the following:
in ModuleA call some EJB method from ModuleB and in ModuleB call some
method from ModuleA. This results in ModuleA having ModuleB in it's
dependencies and vice versa. However Netbeans gives me an error: "Can't
add cyclic references".

How can I work around this problem?

Regards,
Krzysztof
