>
>
> If the paramter contains changes, the update process runs as expected.
> So the expected behavior would be to do the update even if the paramater
> didnt change, or to do no updates and complete the update request without an
> error message.
>
> this is reproducible with the folowing steps:
> # edit a paramater context that contains parameters that are bound to
> running processors.
> # change the value of the parameter and submit the Edit Parameter dialog
> # reopen the Edit Parameter dialog and change the value back to the original
> value and submit the dialog
> # submit the Edit Parameter Context dialog
>
