How to limit filling a multiple choice field to a maximum of 5 items per ticket with JMWE?

You need to obtain the size of your custom field (based on selected options) associated to the issue. Here is a possible codes that I used in the past on determining the size (thanks to @Nic Brough -Adaptavist- response in an older case ask in the community)

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.customFieldManager
def customField = customFieldManager.getCustomFieldObjects(issue)?.find { it.id == "<your multi select custom field id>" }

return issue.getCustomFieldValue(customField).size()

Once you obtained the size, then you can build the logic to raise an error when user selects more than five options to prevent issue from being created.

Hope this helps.

Hi @rangel de oliveira machado

using JMWE, you can use a Build-your-own Validator with something like:

! issue.customfield_10200 || issue.customfield_10200.length <= 5

where you'll need to replace customfield_10200 with the custom field ID of your checkbox field (which you'll find on the "Issue Fields" help tab below the editor).

Hi @Joseph Chung Yin I'm afraid your answer only works on Server/DC, not Cloud, does it? Rangel mentioned he's using Jira Cloud when he raised his question.

@David Fischer -

You are right. Sorry for the missed... Import class libraries are not supported in the CLOUD.

Even though my suggested solution is for Jira DC, the overall concept should still be applicable in the CLOUD env.

Essentially, you have to obtain the size of the field options (options selected by users) as a counter, and then use that counter value to raise your validation error during issue creation process.

@David Fischer -

We use JMWE add-on too and implemented your suggested solution too. Both JMWE and ScriptRunner add-ons are excellent add-ons for any Jira env.

In CLOUD env, you have to use groovy script for issue to obtain the custom field option counter.
