Concatenate text fields without null

Abstract

This code snippet concatenates two text fields ignoring null values

Logic

Access the text fields and concatenate them

Snippet

org.codehaus.groovy.runtime.NullObject.metaClass.toString = {return ''}
<First text field> + "<Delimiter>" + <Second text field>

Placeholders

<First text field>

linkedIssue.get("description").toString()

"<Delimiter>"

<Second text field>

issue.get("summary")

Examples

The output of this code is a String which you could, for example use to:

• Set the summary of the issue to the concatenation of two custom field values, say Customer Name and Machine details in:
  • one of the Set Field Value post-functions
  • one of the Transition issue post-functions on the transition screens, if any
  • the Create issue post-function under Set fields of new issue section

org.codehaus.groovy.runtime.NullObject.metaClass.toString = {return ''}
issue.get("Customer Name") + "-" + issue.get("Machine details")

• Include the key and description of the issue in the comment while notifying the customer that their issue has been resolved in one of the:
  
  • Comment in one of the Comment issue post-functions
  • Subject/HTML body/Text body of Email issue post-function
  • JQL search expression of Link issues current to issue

org.codehaus.groovy.runtime.NullObject.metaClass.toString = {return ''}
"Your issue" + issue.getKey() + " - " + issue.get("description") + "has been resolved."

• Compare the text in a conditional execution script to:
  • Run a post-function
  • Run a condition
  • Run a validator
  • Unlink issues
