How can I check as a validator in workflow transition, that a Cascading List field is not empty?

[Tilman Ulshoefer]

Dear everyone,
I want to make sure that my cascading list field "Agile Release Train/Team" is not empty during a workflow transition.

When I add the validator "Fields Required (JSU)", Jira only checks the first level (parent) of the field, allowing the children keep being empty.

Therefore, I want to test whether a Regular Expression Check (JSU) works. What value do I need to enter into the field "Regular expression" to check that the user gets an error if the parent has a valid value, however, child = none?

Hi @Tilman Ulshoefer 

This should be possible. I found an old KB article from JSU (before Appfire bought them).

Please see the article here. I think should solve your issue,

Thank you for this link, Marc. 

Unfortunately, we failed benefiting from it. My level 1 value is "ART1", and the two level 2 fields are "Team1" and "Team2". We tried everything like (ART1|((Team1|Team2), .+?)), however, did not get it working.

Hi @Tilman Ulshoefer 

I would reach out to Appfire the vendor and raise an issue at their end to see if and how this configuration is possible.

Thank you for your advice, just created a request with appfire, Marc.

I got the correct answer by appfire, which solved my case: Cascading List Field - How check that child is unequal to None? - Appfire Atlassian support - Jira Service Management.

Have you check the children issues is applied the same workflow like the parent issue ?

It is not about parent and child issues, trung. It is about parent and child values in a cascading list field, assigned to the same issue.
