Regarding workflow conditions based from custom field value

[Franco C. A.]

Hi, I'm just at two weeks of manipulating JIRA service desk server-based (3.12.2, JIRA core v7) and I have a problem with workflows. 

What I have to accomplish is that after a certain status on the workflow, there is a screen showing a select list field and there's three options on it. And each option has its respective transition of statuses in the workflow. 

Now, how could I do this and I'm only on evaluation. I really look forward someone could help me with this, thank you very much.

Hello,

Why would you need to show a user transition in a select list. All transitions can be chosen by user from the view issue screen. That would be an additional action for user to open a transition with a screen just for choosing another transition.

Indeed.  Atlassian deliberately designed all styles of transitions to be immediately available to the users and a lot more simple to use than popping up boxes, which is extra clicks and makes the user think more, even though they've already decided what they're doing.

On the view screens, transitions are a single labelled click, or a drop-down taking you directly to a status, on boards you click and drag.  They only pop up boxes when you need them to enter more data.

Exactly. I don't recommend showing user transition in a select list either. JIRA has got better way.

[Nic Brough -Adaptavist-]

Well, in the new beta issue view, the transitions are shown as a status drop down which lists all the target status for possible transitions.  (I don't like it a lot, it breaks the "two routes to one status" trick a lot of people need to play)

[Vishnukumar Vasudevan]

Oh... is it ? I don't like it either. 

[Franco C. A.]

Well thank you for your inputs. But my main concern is to automatically direct the workflow based on the selected field to skip seeing the other transitions.  Would that be possible?

You should write workflow conditions to hide some transitions. You can use built-in conditions or use plugins such as Power Scripts or ScriptRunner to write custom conditions.
