Auto transition based on custom field value with Groovy script

[Tomasz Bryła]

Hi 

I working on project, where issue must change status automatically based on custom field value set on previous step. I try do this by Automation for Jira Add-on, but it work too slowly and I want to use Script Runner to this. I use Fast-track transition an issue  but I would have to use several such functions. So i try to do this by this script, problem is that doesn't work, can you tell me what I do wrong?

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.IssueImpl
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.project.ProjectManager
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.user.UserUtils
import com.atlassian.jira.workflow.WorkflowTransitionUtil;
import org.apache.log4j.Category
import com.atlassian.jira.issue.comments.CommentManager
import com.opensymphony.workflow.WorkflowContext
import com.atlassian.jira.workflow.WorkflowTransitionUtil;
import com.atlassian.jira.workflow.WorkflowTransitionUtilImpl;
import com.atlassian.jira.util.JiraUtils;
//boolean status = false
WorkflowTransitionUtil workflowTransitionUtil = ( WorkflowTransitionUtil ) JiraUtils.loadComponent( WorkflowTransitionUtilImpl.class );

IssueManager issueManager = ComponentAccessor.getIssueManager()
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
CustomField myCustomField = customFieldManager.getCustomFieldObjectByName("Category")
String myCustomFieldVal = (String) issue.getCustomFieldValue(myCustomField)
if(myCustomFieldVal.equals("IT"))
{
workflowTransitionUtil.setAction (5)
}

To transition correctly following lines are needed

 workflowTransitionUtil.setIssue(mutableIssue);
 workflowTransitionUtil.setUserkey('userToTransition');
 workflowTransitionUtil.setAction(actionID);
 workflowTransitionUtil.validate();
 workflowTransitionUtil.progress();

And generally speaking, your import lines should be less than your code lines :P.
