Update an item causes recursive loop

Hi team,

So I am looking to run a method on an item whenever it is updated to update two hidden properties on the item that drive some functionality later on down the workflow.

The issue I am having is that when I use the onAfterUpdate event, because the method updates the item it causes a recursive loop and runs itself indefinitely.

I attempted onAfterVersion however this caused two weird scenarios - the logging wouldn't show the correct result until the second time the item was saved and even then it never actually updated the properties. I have this same event running onAfterAdd and it works successfully there but I need it to update anytime the item is saved.

Finally, I got the idea to run it via a wrapper from a client event on the form. In this case, onFormPopulate causes the recursive loop again, and so I am attempting a field even for onChange of the field that drives these in question. It still seems to have an issue so any suggestions would be welcome.

    It's possible. I did end up getting everything working. 

    I ended up creating a client wrapper as a method triggered from a form event onFormPopulate. The client method validates that the item is locked then calls the server method to perform the update. It's working as expected now.

      Thanks for this Angela. The system does definitely collapse :) I don't know that this will work for my case.  In the example here, once the property is set the method will not fire again. In my use case, I need the method to fire and update the property everytime the item is saved. If I use this method, it will apply the first time but then not in any subsequent attempts I believe.

        Have you tried the attribute serverEvent = 0 in your query? 

        Edit: --> myCall.setAttribute("serverEvents","0");

    Why not to use OnBeforeUpdate? In this case you don't need an additional update. Just change the properties of "this".

      Thanks for the suggestion, I never considered that. I'll run a test on this in the future but I've got it working another way.
