Hi all, what we would like to do is to have the capability to don´t let developers move a story to the open status via a transition unless there is at least one task already created.
What we did is to create an aggregate propertie that calculates the number of children (tasks) for current story. After that we wanted to use that property as a condition for the transition but we realized that you can´t select aggregates function in the "if" condition on the edit transition screen.
Do you know if we are doing something wrong or if there is another better way to do that?
Thanks in advance,
