You can't natively.  Options though:

  1. Use a validator to refuse entry of more than one (there are several plugins on the marketplace that can provide that validator).  I'd avoid that one, as it's ugly for the users
  2. Hack the "edit" field template for component so that it is only single select.  Neat, but you have to maintain it in upgrades etc
  3. Use the Script-Runner Behaviour plugin to amend the field type 
  4. Write your own javascript to amend the field type.

I'm not averse to option 2 if you need a global change, but it does add testing burden to your upgrades.  Option 3 is probably the best one.


As follow up to Nic's answer, I'm listing here how one can do using Script Runner Behavior

import com.atlassian.jira.bc.project.component.ProjectComponent
import com.onresolve.jira.groovy.user.FieldBehaviours
import groovy.transform.BaseScript

@BaseScript FieldBehaviours behaviours

def components = getFieldById("components").getValue() as List<ProjectComponent>
if (components.size() > 1){
getFieldById("components").setError("Please select only one component related to your work.")

Hope that helps to anyone who still looking for easy way to get it done for specific project.

Anybody know what the script would be to check if component has more than one entry?

What type of script?

Groovy / Script Runner

I added a solution for the JIRA version 6.4.13 in the ticket

 JRA-12543 - Need ability to change project component field type from multi select to single selectCLOSED ,

hope it helps.
