if you try "groupby resource.availability" it will throw an exception and display an error message in the UI. this should be supported.
rev2604 - support pivoting on resource.availability expression to test: * create a new group definition * edit the expression set and enter "groupby resource.availability" * click save // this should succeed, previously it failed * then, calculate the groups expected results: * one group for UP resources (assuming any exist in inventory) * one group for DOWN resources (assuming any exist in inventory) * one group for UNKNOWN resources (assuming any exist in inventory [this can happen when a resource as been imported into the inventory, but an availability report hasn't been sent up to the server])
I get 2 groups (because I don't have any with UNKNOWN avail). rev2626 windows/oracle
