How do I run a script when the value in the customfield?

How do I run a script when the value in the customfield, if the value to which the change is unknown to me.
Is that possible? Thank you in advance.

Could you give us more detail on:

  • when this should run.  "a value in a field" does not tell us when you want to do it.  (Think of it this way - I wrote "dave" on a note.  My note has a value of "dave".  Do I run a script when I write the note, when I throw it away, or every second that "dave" is on it?)
  • You say "if the value to which the change is unknown".  That's not an English clause, and hence makes no sense.  At a guess, you are trying to say that you want to update a custom field with some data, but the clause implies that you do not know the data.  This will not work.  Imagine that you hire someone to paint a wall.  They come to your house and ask "what colour do you want the wall?".  When you say "I don't know", they cannot do it.  That's what you have done to us here.

I'll try to explain.
I have a drop-down list, the script should be triggered when any item.

That's how I'm trying to implement it:


IssueManager issueManager = ComponentAccessor.getIssueManager();

def change = event?.getChangeLog()?.getRelated("ChildChangeItem").find {it.field == "customfield_10200"}
if (!change) { ("Developer changed" + change.oldstring ) ("Developer changed" + cchange.newstring )


But the mistake: java.lang.NullPointerException: Cannot get property 'oldstring' on null object

I'm doing something wrong, but I can not figure out what it was.


>the script should be triggered when any item

when any item what?

Your code is from a listener though, and it needs a tweak if I'm understanding what it's for.  Try
