I'm having a hard time figuring out what's going wrong with the script below. The purpose of the script is to construct a collection of children components. This collection will later set the parent component list.

Lines 80 to 113 is where I think things are going wrong, but I can't figure out why.

Code:

package com.custom

import com.atlassian.jira.event.issue.AbstractIssueEventListener
import com.atlassian.jira.event.issue.IssueEvent
import org.apache.log4j.Category
import com.atlassian.jira.bc.project.component.ProjectComponent
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.security.JiraAuthenticationContext
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.issue.changehistory.ChangeHistoryManager
import com.atlassian.jira.issue.changehistory.ChangeHistoryItem
import com.atlassian.jira.bc.project.component.ProjectComponentManager

import com.atlassian.jira.bc.issue.IssueService

class ComponentListener2 extends AbstractIssueEventListener {
    Category log = Category.getInstance(ComponentListener.class)
 
    @Override
    void issueCreated (IssueEvent event) {
    	log.setLevel(org.apache.log4j.Level.DEBUG)

	if (event.issue.isSubTask()) { makeUpdate (event, "add") }
	else {  
		// find correct Other component
		ProjectComponent projectComponent = ComponentAccessor.getProjectComponentManager().findByComponentName (event.issue.getProjectObject().getId(), "Other")

		// set up for update
		MutableIssue myIssue = event.issue
		IssueManager issueManager = ComponentAccessor.getIssueManager()
		UserManager userManager = ComponentAccessor.getUserManager()
		Collection <ProjectComponent> comps = []
		comps.add(projectComponent)
		
		// update
		myIssue.setComponentObjects(comps)
		issueManager.updateIssue(userManager.getUser("automation"), myIssue, EventDispatchOption.ISSUE_UPDATED, false)

	}

	log.debug("--- Made it to the end of create method. ---")

    }    
    
    @Override
    void issueUpdated (IssueEvent event) {

	// understand the update made to the issue
	ChangeHistoryManager changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
	List <ChangeHistoryItem> changeHistoryItems = changeHistoryManager.getAllChangeItems(event.issue)
	ChangeHistoryItem lastItem = changeHistoryItems.get(changeHistoryItems.size()-1)
	log.debug ("last item: ${lastItem.getField()}")

	// going to make the change if it was a component change and not done by automation
	if (lastItem.getField().equals("Component") && !lastItem.getUser().equals("automation")) { 
		makeUpdate(event, "update")
	} else { log.debug ("We ended up in this useless stub.") }

	log.debug ("--- Made it to the end of the update method. ---")

    }
    
    @Override
    void issueDeleted (IssueEvent event) {

	if (event.issue.isSubTask()) { 
		makeUpdate(event, "delete")
	} else { log.debug ("We ended up in this useless stub.") }

	log.debug("--- Made it to the end of delete method. ---")    
    }

    // this method does all the heavy lifting 
    void makeUpdate (IssueEvent event, String type) {


	// create my collection
	MutableIssue myIssue
	if (event.issue.isSubTask()) { myIssue = event.issue.getParentObject() }
	else { myIssue = event.issue }
	Collection <Issue> myTasks = myIssue.getSubTaskObjects()
	Collection <ProjectComponent> comps = []

	// make sure we have children
	if (myTasks.size() > 0) {
		myTasks.each { t -> 
			comps.add(t.getComponentObjects()) 
		}
	
	// no children but keep in mind that new task isn't yet a child
	} else if (!type.equals("add")) {
		ProjectComponent projectComponent = ComponentAccessor.getProjectComponentManager().findByComponentName (myIssue.getProjectObject().getId(), "Other")
		comps.add(projectComponent)	
	}

	// add requires an additional check since the new task is not yet a child
	if (type.equals("add")) { comps.add(event.issue.getComponentObjects()) }

	// prepare for update
	comps.unique()
	log.debug ("comps: ${comps}")
	IssueManager issueManager = ComponentAccessor.getIssueManager()
	UserManager userManager = ComponentAccessor.getUserManager()

	// update
	myIssue.setComponentObjects(comps)	
	issueManager.updateIssue(userManager.getUser("automation"), myIssue, EventDispatchOption.ISSUE_UPDATED, false)
    }	
}

wouldn't you know right after I ask that I figure out my problem. i shouldn't be 'add'ing to my collection. i should be 'plus'ing to it since i'm combining a collection with a collection.

Or use .addAll rather than than .add.
