I'm new using Azure DevOps Server and i having some problems creating rules. I'm trying to make a rule that doesn't allow the user to change the state of a Feature on the Board if this Feature doesn't have any attachment on it.
The rule i created is something like this: Test Rule . Right now with this rule it still permits the user to change state.
I practiced with other rules where i made required to have a description on state change and it worked fine not allowing the user to change state and showing "error" on the board.
I was testing with the querys if the feature I was using had any files attached but the result showed the work item correctly when i used that "Attached File Count" = 0.
If someone had some issue similar to this and can help me with it I'll apprecite it very much.
