Need to restrict Component/s to single select using ScriptRunner

Tammy Robinson

I have researched and found numerous posts about restricting the Components field to a single choice.  However, I don't see a specific way to do this with ScriptRunner.  I am totally new to ScriptRunner so am wondering if there is some example logic already to do this.  If not, do I accomplish this with a behaviour or a script validator in the workflow? I just need direction on what is the correct method.  Any advice is greatly appreciated.

Hello, 

You could add a behaviour. In the behaviour add Component/s field and paste the script below to the serverside script

import static com.atlassian.jira.issue.IssueFieldConstants.*

def cfComponent = getFieldById(COMPONENTS);
def compValue = cfComponent.getFormValue()
if (compValue instanceof List) {
 cfComponent.setError("too many components chosen");
} else {
 cfComponent.clearError();
}
