JMWE groovy script to set field value based on dropdown

[Jemima James]

I have a dropdown field A with the following values:

1 - very low

2 - low

3 - medium

4 - high

5 - very high

I want to set the field B based on the dropdown value.

If A is 1 - very low set B=Green

If A is 2 or 3 set B = Yellow

Else set B = Red

I dont have jira automation. I'm trying to do this using JMWE and regular expressions. But I do not know how to write the groovy expression to get this outcome.

Can someone please help me out?

Hi @Jemima James 

you can use a Set Field Value post-function, select the field to set (B in your example), select "Groovy Expression" as the value type, and for the value use a script like this:

switch (issue.get("A")) {
  case "1 - very low": 
   return "Green";
  case "2 - low":
  case "3 - medium":
   return "Yellow";
  default:
   return "Red";
}

Hi @David Fischer ,

I would like field B to be updated whenever the value changes in field A. Not just on workflow transition.

Hi @Jemima James ,

for that, you can put the aforementioned post-function in a JMWE Event-based action that reacts to the Issue Field Value Changed event for field A.
