But if the rset is empty, I want my controller to stay on the same view but display a message in the notification bar, something like 'No results were found sorry'.

for form posting and processing of the result.
Existing js functions that may be useful / source of inspiration:
- validateForm: to post a "regular form" (ie processed by the 'edit' controller)
- updateMessage: to display a message in the notification bar
- reload: to reload part of a page with result of a view/component/etc.
Hope that helps.
