> Steps to recreate:
> 1. All processors stopped
> 2. Add uuid to "Attributes to Send" in the InvokeHttp Processor
> 3. Save and close config dialog
> 4. Open same config dialog and remove uuid field so that is is "No value set"
> 5. Apply changes and web UI will crash and indicate error has occurred
> and below will seen in user log
> 6. Hit F5 and browser reloads UI just fine
> See attached template.
