Transition warning message

[Wessel de Jongh]

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:
https://stackoverflow.com/questions/6606386/how-to-add-new-dialog-on-workflow-transition-in-jira 

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?

Hi @Wessel de Jongh 

There are a few questionable bits in that post you are referring to.  One it was from 2012, which so much has changed I probably don't need to continue, but here we go, it is also for server and not cloud, and finally even on server in 2012 I do not believe there was ever a magic name for a field that would act as the user says, even if they did "remember correctly".

So now that I have beat up the stack overflow post, you would like a popup for some transitions, but you are probably using the "all" transition to go into most of your statuses.  Some of the stack overflow post is correct.  You need to go to the transitions you want a popup for, and add screens with the fields you'd like the user to edit.  If you used the all, and only want the screen for certain transitions, you will need to create these specific transitions and add your screen.
