customefield type Label : Length of each entered input into the field should be 8

[Anupam Sinha]

Hello Community

I am stuck with a scenario. Please help me. I have a custom field type : Label in my issuetype Epic. Name of Label (customefield is) :  Additional IDs.

Scenario

User is expected to enter minimum 1 and maximum 10 Ids into the field and each entered Id must be 8 Characters long only. If user enters more than 10 Ids, an error should be shown on the screen. If user enter an Id which is not equal to 8 characters should throw an error on the screen as user updates epic.  

I have Scriptrunner installed on my jira server edition. 

Please advice me how to implement this constraints on the field. 

Thank you .

You can add a Validator of type Simple scripted validator [ScriptRunner] with a Condition like this:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.fields.CustomField
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
CustomField myCustomField = customFieldManager.getCustomFieldObjectsByName("Your Custom Field Name")[0]
boolean allValidLength = true
int numLabels = 0
issue.getCustomFieldValue(myCustomField).each{
	numLabels++
	if(it.toString().size() != 8){
		allValidLength = false
	}
}
return numLabels <= 10 && allValidLength

And an Error Message like: Each Additional ID must be 8 characters in length, and there must not be more than 10 of them.

Thanks for replying and help @Payne

I am not sure at which status I should add this validator. I have large workflow with more than 10 statuses. User wants check should be in place at screen and irrespective of status of Epic. 

Thanks,

In a situation like this we have put a validator near the beginning of the workflow when the issue is created and one more near closure. Think about when the user will provide those IDs and go from there.
