For the workflow of a certain work item I want all transitions to be possible, but that a warning pops up if you do certain transitions. I've seen a few discussions about this in these forums, but they all lead to installing some plugin which I don't want.
I've seen a solution (not fully explained) where you use a custom field with "Message Custom FIeld (for edit)" field type. If you use it in a screen it would give some sort of popup window. I did make a custom field with that specific type, but from there I am stuck as I don't know what to do. This is a link to the stack overflow form I came across:

Can somebody maybe tell me if this is really possible this way and if so how I would make it work with the custom field and screen?
