How do i specify my own error message for the Comment field in Jira Behaviours?

[Andrew L]

Hi

I have a Jira Behavior attached to the fixVersions field.

Here is the code snippet:

   def comment_formfield = getFieldById("comment")
   comment_formfield.setRequired(true) 
   comment_formfield.setHelpText("Please provide a reason for changing the Fix Version.")

However, i don't see my customized error message.  Instead, i see (the standard message?) :

       You must enter a value for this field

below the Comment textarea.

What i am doing wrong?  How can i get my own custom error message to show up below the Comment textarea?

I changed from setHelpText() to setError() and i got the expected result/behavior.

However, when i provide a comment and click on "Update" button, nothing happens and the Comment field still shows my custom error.

If i switch back to setHelpText(), then i am able to click on "Update" after seeing the "You must enter a value for this field" standard error.

So how do i get my custome error message to show up and also allow the user to click on "Update" to save the changes?

Thanks
