Hi Kunal,
no there is no workaround for sorting. But there is a way to filter during runtime by priority e.g. But this is a kind of a static approach, that means you have for each filter criteria a button and at least one that resets the list. By implementing buttons that sets a specific value via a backround transaction and initial value rules. After that you have to implement a include rule that validates these flags for the collection objects. Based on that the collection will be filtered by these parameters. In fact you have to build a logic that sets flags in the objects to achieve that.
The user then has the possibility to push a button and gets the list filterd by the underlaying logic.
In short words. You have a button for Prio High, Medium and Low. The mechanism behind the buttons sets a flag or several flags. With the include rule you validate these flags and the result will be the condensed list. Ok it is not sorting but filtering regarding specific requirements and the user sees only the result based on the criteria he was choosen, like a specific priority.
Kind regards,
Mike
