[kepler-dev] Looping a process in kepler

I am trying to repeat a process using an if-then-else logic and I get struck
Here is the scenario:
I have three processes [ not sure if thats the right word, it can be
considered as modules doing a specific task] in a pipeline, say process A,
In process B, if the output is "xyz" I have to repeat process B until I get
the desired output, in which case, the control moves to the next module down
the pipe. Each module/process is a composite actor, having an input port and
an output port. I have a SDF director for the main workflow which should be
run only once.
How do I trigger process B again?
I get an error message saying that the "output port drives the same relation
as the external input port, this is not legal in SDF" every time. is SDF
appropriate for workflows such as these?
since I use a pipelined approach, I do not want to use PN director, as each
component will run in its own thread.
can someone give me an example for looping which does not involve integer
