[Teja]

Hi,

Need to validate for the below scenarios

When I select "Feature Note" value from Documentation (multiple choice field) and Feature Note Developer (user picker field) is null, then I need to show Feature Note Developer is required validation message.

When I select other than Feature Note value Feature Note Developer is not required. I mean it should proceed transtion.

I tried some possible ways but it didnt work.

Any help would be apprecited.

Thanks

It should be like this:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.customfields.option.Option
import com.atlassian.jira.issue.fields.CustomField

Issue issue
CustomField documentation = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Documentation")

for(Option option: ((List<Option>) issue?.getCustomFieldValue(documentation))){
    if(option.getValue().equals("Feature Note")){
        CustomField developer = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Feature Note Developer")
        return issue.getCustomFieldValue(developer) != null
    }
} 

return true
