Having trouble with accessing fields with scripts

[CJ_Marchand]

Hi everyone.  

I am writing some code to access fields but it is not working. 

First off this code is in the Initializer section of a behavior.

In the code below at line 14 I am trying to get the value of the sys "Work Item Type" field but it is returning null.  I know at this point no selection has been made but I would think it would return the default value.  

On line 20 I am trying to get access to the current issue to get a hook into the custom fields.

It is also failing.

Any help would be appreciated. 

Thanks,

C.J.

It's will work on Listener like that

if(issue.fields.issuetype.subtask == true){    
  String parentkey= issue.fields.parent.key  
}

and if you are in script console do this:

 def issueKey = 'COPY-19' // enter you sub task key here

def result = get('/rest/api/2/issue/' + issueKey)
 .header('Content-Type', 'application/json')
 .asObject(Map)
if (result.status == 200){
 def parentIssue = result.body.fields["parent"]
 return parentIssue["key"]
} else {
 return "Failed to find issue: Status: ${result.status} ${result.body}"
}
