Restricting a Behavior to create transition

[Nikhil]

I am trying to add a BEHAVIOR to set description with default values which i can edit before i create the ticket. And i am using the following script for it. Which work fine in bits and pieces, the not working parts comes in when i edit the ticket it erases the fields edited values and fills the default values.

so i tried a workaround by adding to the field and setting a condition to the workflow action.

Please need your help guys.

Script:-

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import groovy.transform.Field

def StoryDefaultDescValue = """Default values for story"""

def DefectDefaultDescValue =""" Default values for defect"""

def projectKey = getIssueContext().getProjectObject().getKey()
def issueTypeName = getIssueContext().getIssueType().getName()


if(getAction()?.id != 1 || issueTypeName == "Story"){
getFieldById("description").setFormValue(StoryDefaultDescValue)}

if(getAction()?.id != 1 || issueTypeName == "Defect"){
getFieldById("description").setFormValue(DefectDefaultDescValue)}
