Keeping ScriptRunner postfunction from updating history/Dashboard feed

[Jason Adam]

In our Jira workflow, especially on creation of one of our types, there are several group "Review Inputs" fields that depending on the required groups selected in another field, we either put <not yet submitted> or an empty string so the field will be "hidden" until a user selects to provide input for that group (at which point the "GroupA Review Input" field is displayed, for example).

The problem (and I use that term loosely) is that all the changes we do in our postfunction scripts show up in the issue history and in the system dashboard activity stream.  And since we have several fields that we do stuff to, the history and stream can get very verbose.

Is there a way to do all these updates without having them displayed in the history/stream?  Jira records all changes and that's good, but can you be selective so that postfunction updates aren't displayed as a change?

Thanks!
