Scriptrunner - Behaiviour: how to stop updating an issue because of an specific condition

[Günter Halmans]

Currently, I'm trying to define two conditions regarding the component field in a subtask:

1. the field should be required --> I realized this requirement setting the specific option in the corresponding field configuration. Everything fine.
2. the field should only contain one component, not more and not less than one...

I tried to define a behaviour with respect to the specific project and field. I was successfull in checking the amount of components in the specific subtask and to send a user message or an invalid input message.

Now my question: When I'm entering two components in the edit dialogue the behaviour fires, but jira updates the issue (what I wanted to avoid) although the behaviour throws the exception.

Here is the snapshot of my behaviour code:

def issueManager = ComponentAccessor.getIssueManager()
def issue = issueManager.getIssueObject("ITP-25")
def NumberComponents = issue.getComponents().size()
log.debug "NumberComponents: " +NumberComponents

if (NumberComponents != 1){
     throw new InvalidInputException("component", "Only one component is allowed")
     return null
}

I tried some alternatives, e.g. "return false" or throwing the invalidInputException without the assignment to the field...but nothing helps. Thus, I assume I'm not on the right track...

Has someone an idea? Thanks a lot in advance!

Hi @Günter Halmans

Have you tried

somefield.setError("Only one component is allowed")

[Günter Halmans]

No, I'm going to try it in a few minutes :-)

what kind of object is "somefield"?

[Tom Lister]

the field you would like the error message to show against - maybe the Components field would work, not sure

your code will also have to clearError() when the condition is clear

Hi Tom,

it works! Thanks a lot -  You have saved some painfull hours of my time :-)
