How to make the component a single selection field.

How to make the component a single selection field. Currently it a multiple component selection field. I want it to be a single component selection field.

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.

Both possible fixes aren't very nice:

You can either (as usual) buy a commercial plugin, which adds to your JIRA costs and can cause problems with JIRA updates; or you can try a suggestion from 2014 where someone suggested changing JIRA code but didn't even test it (but then, you can just set up a Staging JIRA and try there.).

Plugins:

"JIRA MIsc Workflow Extensions" apparently contains a Workflow Validator "field has single value"

"ScriptRunner" apparently can do something similar, but is more expensive.

The code hack:

Or try the single field value validator provided in this plugin https://plugins.atlassian.com/plugin/details/292
