Update priority field if user does not have a permission "Assign issues"

[zaharovvv_suek_ru]

We are using ScriptRunner.
We are changing a priority field in Custom Listener when an event `Issue updated` is happened.
This code updates a `priority` field of issue if user has permission "Assign issues" in Issue Permissions tab of my project.
However, if user does not have permission "Assign issues" in Issue Permissions tab of my project, then this code is not updating priority field.
What can I do to update priority field if user does not have a permission "Assign issues", but user has a permission to "Edit Issues"?
In my view, it should be enough to have a permission "Edit Issues" to be eligible to edit priority field. Is it correct?

 log.warn('2. ***** Priority of issue is set to: *****' + idPriorityLoIssue)
 def seqFieldLinkedIssue = customFieldManager.getCustomFieldObjects(linkedIssue).find {it.name == "Послед."}
 if(seqFieldLinkedIssue){

 seqFieldLinkedIssue.updateValue(null, linkedIssue, new ModifiedValue(linkedIssue.getCustomFieldValue(seqFieldLinkedIssue), sequenceFieldValue),changeHolder)

 } else {

 }
}

The issue is in your last 2 lines.

selectedValue is specific to the parent issue, attempting to check this for a null value in the every{} block is not achieving what you think.

Here is the complete logic that you are trying to accomplish if I understand correctly

issue.subTaskObjects.every{subTaskIssue->
    def UOTypeValue = subTaskIssue.getCustomerFieldValue(cf)
    UOTypeValue != null
}

 And it can be further simplified because of the built-in groovy truthiness

issue.subTaskObjects.every{it.getCustomerFieldValue(cf)}
