I have a rule that has been running without issue for a while. I just went in to it today to tweak some of the settings. Now when I click on the "Actions" to edit something I get an error message:
errorgroovy.lang.MissingMethodException: No signature of method: java.lang.Integer.size() is applicable for argument types: () values:  Possible solutions: is(java.lang.Object), find(), div(java.lang.Number), use([Ljava.lang.Object;), times(groovy.lang.Closure), div(java.lang.Character) on line 2494 (selectActions)
Anyone know how I can fix this? Do I need to delete and start over?
