Guard Conditions on EPCM signal in don't seem to work?

Hello,

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?

Thanks

Conrad

    Hi Conrad,

    You can't put a guard condition on the signal in. Signal in is always activated when it receives data.

    But, you can work around it by passing the data from the signal in to a form and then trigger a custom action with guard condition.

    You can use my blog to see how to use spinners to do similar thing:

    Hope it helps,
