Copy attachment to subtasks

[Konstantin]

The subtasks are created in postfunctions of transition in a parent issue. There is postfunction to copy attachments on transition "create" inside the subtasks' workflow But my attachments are copy only to the first task. Why?
I use add-on JMWE.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.AttachmentManager
AttachmentManager attachmentManager = ComponentAccessor.getAttachmentManager()

def listcomponents = ["comp1","comp2","comp3",...];
def needcomp;
def res;
def attach = []

try{
 listcomponents.each{comp->
 if(issue.get("components").any{it.getName()==comp}){
 switch(comp){
 case ["comp1","comp2","comp3"]:
 needcomp = "comp4";
 res = 1;
 break;
 case ["comp5"]:
 needcomp = "comp6";
 res = 1;
 break;
 case ["comp6","comp7"]:
 needcomp = "comp8";
 res = 1;
 break;
 
 if(res){
 throw new Exception("return from closure")
 }
 
 }
}
catch (Exception e){
 issue.getParentObject()?.get("subtasks").each{subtask->
 if(subtask.get("attachment") && subtask.getAsString("components").contains(needcomp))
 {
 attach += subtask.get("attachment")
 }
 }
 
 attach.each{file->
 attachmentManager.copyAttachment(file,currentUser,issue.key)
 }
}

Solution:
Line: 

if(subtask.get("attachment") && subtask.getAsString("components").contains(needcomp))

change

if(subtask.get("attachment") && subtask.get("components").any{it.getName()==needcomp})
