Need validator for assignee in role

[Adam White]

I just need a validator script for a transition. I'd like a validator for when an assignee has to be in a certain project role. 

I found this code: 

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.security.roles.ProjectRole
import com.atlassian.jira.security.roles.ProjectRoleManager

ComponentManager componentManager = ComponentManager.getInstance()
ProjectRoleManager projectRoleManager = ComponentManager.getComponentInstanceOfType(ProjectRoleManager.class) as ProjectRoleManager
ProjectRole devRole = projectRoleManager.getProjectRole("Lead Software Developer")

projectRoleManager.isUserInProjectRole(issue.assignee, devRole, issue.projectObject)

But I dont think it will be future-compatible with JIRA 7. I'm currently on 6.4.11.

There is a built-in method and example for this in Simple Scripted Validator.

isUserMemberOfRole('Lead Software Developer')
