[protege-discussion] infinite loop

[VIDYA VENKITESWARAN]

This is a rule tat i am trying to run in jess integrated with protege


(defrule  checksize (object (is-a Input-Application) (application-type  ?a
))(test (eq ?a "image") ) =>
(if( slot-get(slot-get(slot-get (slot-get  (slot-get
Fipadevice_Instance_24   hw-properties) ui ) screen ) resolution) graphics)
then (printout t "File transfer possible" crlf (modify-instance
Fipadevice_Instance_20050 (transferability  TRUE)))else (printout t "The
file format is not supported" crlf)))

It runs into an infinite loop
how do i avoid this??
