Couldn't figure what the heck was going in my action framework with some merge data. Wanted to see what data was being create within the framework whilst still keeping rollback enabled for save model actions.
Added the merge data to the message. Simple little thing.
Is there a merge code to show the error itself? I'm not getting any errors in the page editor but when previewing, something is breaking on use of one of the buttons with multiple actions in a wizard. Note sure what I can stuff into the error message to get something useful.
