Trying to add validators in Jira workflow for universal validator?

[shreyasjoshi11]

I am trying to check for the custom field "Create sub-tasks" which is a radio button and has the following value - None, Yes, No. I want to add a validator to check if the value is either Yes or No. However, when I have placed the validator, it shows me some errors.

Here is my custom field - Create sub-tasks. 

Here are the errors I get.

Hey @shreyasjoshi11 - I think you're using Workflow Enhancer for Jira, yes? Huh, their validator syntax looks similar to Jira Expressions (on Cloud), but I now realize this is a DC/Server app. Neat.

So anyways, when you create a custom field of type Radio Button, if it is not set to be Required, then the "None" option shows up automatically.

But as @Alex Koxaras _Relational_ correctly points out, it holds a value of 'null'.

But because you want the validator to "pass" if the custom field is NOT null, I think you need to check for the converse:

{Create Sub-tasks} != null

[shreyasjoshi11]

It says - Parsing of the expression has failed. Please check its syntax. You entered: {Create sub-tasks} != null. This expression will always evaluate to <b>false!</b> System message: Lexical error at line -1, column -1. Encountered: "-" (45), after : "{Create sub"

I am using - 

Update parameters of the 'Universal Validator' Validator for this transition.

Yes, it is hosted on the server rather than the cloud.

Ah, ok, looks like this add-on doesn't support the word 'null'. I got it to work with an expression like this:

{Create Sub-tasks} != ""

Please let us know if this works for you!

[shreyasjoshi11]

Still it doesn't work - 

Parsing of the expression has failed. Please check its syntax. You entered: {Create Sub-tasks} != &quot; &quot;. This expression will always evaluate to <b>false!</b> System message: Lexical error at line -1, column -1. Encountered: "-" (45), after : "{Create Sub"

[Darryl Lee]

Hrm. It might be case-sensitive. Try:

{Create sub-tasks} != ""

 (I got your field name wrong.)

(Also it maybe doesn't like the -.  Can you also try:

{Create sub\-tasks} != ""

[Darryl Lee]

Ooof, I gave that a try and it also did not work. You probably should contact TNG Technology's support since this is their add-on.

Or maybe @TNG Technology Consulting GmbH might be able to weigh in on this here for those of us who are interested.

The question is why in Workflow Enhancer for Jira @shreyasjoshi11 is unable to create a Universal Validator with a field name that contains a hyphen.

Hello @shreyasjoshi11,

We are sorry to hear that you experience issues with Workflow Enhancer for Jira. Thanks @Darryl Lee for mentioning us.

Unfortunately, I am not able to reproduce your issue locally. Referencing fields that contain a hyphen works fine for me.

May I ask you a couple of questions:

• Are you sure the field is called "Create sub-tasks" or might the real name be different, e.g., due to a translation configured for the field name?
• Can you try to work with the custom field id instead, i.e., using {customfield_XXXXX} != "" with XXXXX replaced by the id of the custom field?

If this does not help, may I ask you to open a support ticket at https://tngtech.atlassian.net/servicedesk/customer/portal/16? Then, we can have a closer look together.

[Darryl Lee]

Huh - really odd. I could exactly replicate @shreyasjoshi11 's issue by renaming my field "Create sub-tasks". Well, I look forward to finding out whatever the fix is. Thanks for the response, @Matthias Bertsch [TNG Technology Consulting] !

Hi @shreyasjoshi11 ,

I'm not familiar with the specific app, but you could write the expression like:

{Create Sub-tasks} == null

It would be helpful if you could specify the app which you use.

I am using a universal validator and my JIRA is hosted on the server and not cloud.
