RavenclawDev: RavenClawDev: reusing agents in another part of atree

Thomas,
The frame is sent by a dialog manager, right?

In our dialog manager we have an agent which calls add_event method of the
backend and passes an object "event_add"


DEFINE_EXECUTE_AGENT( CDBAddEvent,
    CALL("java_be.add_event <event_add error>backend_error")
)

The framework generates the inframe that is passed to the back end.

How would do you embed a galaxy frame in a string when making a CALL to
a back end from the dialog manager?

Is this where your fix-up code comes in? Is your fix-up code part of the
dialog manager (as opposed to being a part of a back-end server)?

thank you,
Svetlana
