Currently when using a grid loop action for selected rows if no row is selected an automatic conditional warning shows and no other actions get processed.
There are a number of circumstances where not completing the action set is problematic. For example, when creating an invoice from billable time and expenses from more than 1 grid, sometimes a grid deliberately has no selected items.
In addition to the current conditional warning would it be possible to have a new action that tests for whether a grid has any rows checked? This would allow us catch and handle the error before Method does.
