I came across an error that will lose your configurator. If you create a User defined method with parameters, add it to a control to execute on field change. Then decide that you need more parameters. Normally you add the parameters to UD method and then the configurator tools allow you to go to where you are calling the method to make needed changes.
In Kinetic you don’t get that opportunity, it will give an undefined error. You will lose your work when you attempt to resolve it. And the configurator is broke, only recovery is if you have a backup that you can import.
You need to comment out your call to the method FIRST and then make the change, then come back and resolve the call. At a minimum Kinetic should not allow changes to parameters if there is a reference to the method.
I have a ticket open on it with Epicor.
