I have a signal coming in from an EPCMProxy event which is then activating a Web Service. All the parameters come across fine and are activating the Web Service correctly but I wanted to put a guard condition on the link between the Signal In and the Web Service so that the Web Service is only called the 1st time and not every time the parameters from the Signal In change.
I put the guard condition in and the logic seems to be correct but it does not work? Every time the parameters from the EPCM Signal In change the Web Service is reactivated?
Any suggestions as to why this might be happening?
