How to add validation for "Issue" which is right below the "Linked Issues" field?

[Teja]

Hi, 

I wanted to check the linking issue has a correct custom field value.

i.e. I have custom field 'Feature Type' and values "Product Feature" and "Technical Feature" on the linking issue and now I want to validate this issue on the other issue which going to link and contain Product Feature or not.

Example: 

On the create screen, "GTN-28761" which is going link to another issue and I want to add validation that GTN-28761 has a value of Product Feature or not to show here (another issue create screen).

Thanks

In the validation phase of the create transition you will have to check if the custom fields have required values on the linked Issues or not.

How to fetch custom field value (since you already have issue Id of the linked issue thus you can get issue object using IssueManager)

Also, the above samples work if you have script runner plugin installed.

Hi Tarun,

I tried this below code, did not work.

I'm a beginner for this Jira thing could you please help me.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.link.IssueLinkManager
import org.apache.log4j.Category
import com.atlassian.jira.issue.link.IssueLink;
import com.opensymphony.workflow.InvalidInputException
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.Issue;

IssueLinkManager linkMgr = ComponentAccessor.getIssueLinkManager()

def customFieldManager = ComponentAccessor.getCustomFieldManager()
//custom field of linking issue
def cField = customFieldManager.getCustomFieldObject("customfield_18815")

def cField1 = customFieldManager.getCustomFieldObject("customfield_18813")
def cFieldValue1 = issue.getCustomFieldValue(cField)

for (IssueLink link in linkMgr.getInwardLinks(issue.id)) {

if ( (cFieldValue1.toString().contains("Product Feature")) && !(link.getSourceObject().getCustomFieldValue(cField).toString().contains("Product Feature")) ) {

invalidInputException = new InvalidInputException("Linked issue " + link.getSourceObject().getCustomFieldValue(cField) + " is not having right value")
throw invalidInputException
}
