Check if the value of a CustomField was changed in a validator (ScriptRunner)

[Justin Volden]

I have a CustomField that is of a multiline Wiki rendered type. I want to validate that the default value (set in a project scope on the field) has been changed/edited/added to to allow a specific transition. how can I do this using a ScriptRunner validator, or other ScriptRunner utility?

Hello, 

You would just need to set up a simple scripted validator on the transition to do this. 

Something like this within the condition should work:

cfValues["Your Field's Name"] != 'The Default Value'

As long as the default value is the same between different issues, this should work fine. You should also be able to set up a behaviour on your workflow transition to do something similar if you'd prefer to do that.  

Hope this helps! Let me know if you have any questions.

Regards, 

Jenna

I did try that, but it always resulted in a false for some reason. I'm wondering if it is because there is wiki markup in the default value, or if I am perhaps not handling multiple lines/line breaks correctly. 

[Jenna Davis]

You'll have to include the wiki markup characters (like, h1 or {quote}) inside of your default value. 

The newline characters are likely also throwing it off, you might be able to use something like:

System.getProperty("line.separator")

To make sure you're getting the correct newline charater. I have not tested this though. You'll just have to play around with the formating of the default value.

Here is where I am at:

ScriptRunner workflow function - Simple scripted validator (condition apply).

import org.apache.log4j.Logger
import org.apache.log4j.Level
  
def log = Logger.getLogger("com.acme.CreateSubtask")
log.setLevel(Level.DEBUG)


String defaultText =  "h1. Change Plan" + System.getProperty("line.separator") + "----" + System.getProperty("line.separator") + 
    "||Step||Estimated start time||Duration||Activity||Implementer||Expected Result||Risk Level||" + System.getProperty("line.separator") + "| | | | | | | |" + System.getProperty("line.separator") +
    "----" + System.getProperty("line.separator") + "h1. Rollback Plan" + System.getProperty("line.separator") + "----" + System.getProperty("line.separator") + "<insert plan text here>"

String currentText = cfValues["Change Plan"]


if(currentText != defaultText) {
    log.debug "True"
    log.debug currentText
    log.debug defaultText
    return true
} else {
    log.debug "False"
    log.debug currentText
    return false
}

 Here is the log output:

017-07-25 11:24:44,283 DEBUG [acme.CreateSubtask]: True
2017-07-25 11:24:44,283 DEBUG [acme.CreateSubtask]: h1. Change Plan
----
||Step||Estimated start time||Duration||Activity||Implementer||Expected Result||Risk Level||
| | | | | | | |
----
h1. Rollback Plan
----
<insert plan text here>
2017-07-25 11:24:44,284 DEBUG [acme.CreateSubtask]: h1. Change Plan
----
||Step||Estimated start time||Duration||Activity||Implementer||Expected Result||Risk Level||
| | | | | | | |
----
h1. Rollback Plan
----
<insert plan text here>

It's still resolving that the text does not match. Not sure where to go to figure out what throwiung this off. 

Any thoughts of what I could try to determine what difference it is finding? Thank you!

I ended up solving this by tokenizing the strings. After that the comparison seems to be working as expected:

String defaultText = "h1. Change Plan" + System.getProperty("line.separator") + "----" + System.getProperty("line.separator") + 
 "||Step||Estimated start time||Duration||Activity||Implementer||Expected Result||Risk Level||" + System.getProperty("line.separator") + "| | | | | | | |" + System.getProperty("line.separator") +
 "----" + System.getProperty("line.separator") + "h1. Rollback Plan" + System.getProperty("line.separator") + "----" + System.getProperty("line.separator") + "<insert plan text here>"
defaultText = defaultText.tokenize()

String currentText = cfValues["Change Plan"]
currentText = currentText.tokenize() 

currentText != defaultText

Oddly enough, if I print both tokenized strings to the log they look identical, but it works so....

I'm glad you got it working! :)
