Hi!

Here is the code ...

public void wdDoInit()

{

//@@begin wdDoInit()

//$$begin Service Controller(-1286588442)

wdContext.nodeZrfc_Menu_R3_Ssm_Get_Favorites_Input().bind(new Zrfc_Menu_R3_Ssm_Get_Favorites_Input());

//$$end

//@@end

}

regards,

Leslie

Hi again,

The problem was resolved, when the Web Application Server was updated with the Adobe components.

Thanks a lot!
