And this is the pull request: https://github.com/droolsjbpm/guvnor/pull/28
Let's wait and see if drools' team apply it.
What I did was basically to add 2 new hook function in JS:
registerBeforeSaveAllButtonCallbackFunction() and registerAfterSaveAllButtonCallbackFunction(). Using them, you can attach your own listeners to, for example, refresh the iframe after the process as been saved.
