Field Required Validator / Either or

[Anette Noll]

Hi all,

after trying a lot with Field Required Validator with optional validation I hope to find the answer here.

Following scenario:

• Create Screen
• In case field A and B are empty 
• field A or B must not be empty

Thank you for help!

Hi @Anette Noll,

Your requirement can be achieved using the Jira Misc Workflow Extensions (JMWE) app. 

Solution:

1. On the creation transition, add the "Build-your-own (scripted) Validator" from JMWE.
2. Add the below Jira expression: 

!!issue.customfield_10081 || !!issue.customfield_10004

Replace 10081 and 10004 with the IDs of fields A and B from your instance. The above expression returns false if both A and B are empty. It returns true in all other cases.

Try the above in your instance. If that doesn't work, let me know the types of the two fields so I can tweak the above script for those field types.

BTW, I'm from Appfire, the vendor of JMWE app. If you've any questions on this, feel free to create a ticket with our support team here.

Hi @Anette Noll

It should be pretty simple in any jira expression-based validator. If either field A or B must be not empty:

issue.customfield_10004 != null || issue.customfield_10005 != null

 Change ID to correct ones for your Jira instance.

I am from Forgappify, and we developed Jira Expression Validator, which is part of the Workflow Building Blocks for Jira free app. In the expression editor, when you start typing the name of your field, you will get a suggestion for the ID.

For some types of fields you, expression maybe slightly different, e.g. for array types you may need to use:

!!issue.customfield_10004?.length 

I hope it will help.

Cheers

Hi @Anette Noll , with the OOTB Field Required Validator, if there are two fields involved it will always be an AND operation. There is not an OR validator natively. If you want to allow a transition if either field A OR B is not empty then you need an addon app.

Hi @Jack Brickey 

thank you for reponse.

Probably you mean JMWE app?

I already use it



No, chance to describe it in the optional validation?

Or are you speaking of another addon app?

Hi @Anette Noll , good to know that you have JMWE. I believe you can achieve with JMWE but I do not have sufficient personal experience with it. However, let me see if I can assist with a bit of Community searching. I encourage you to do the same ... two heads better than one 😉

From my brief research you will need to build your own scripted validator. Other than the documentation link just provided there are examples of similar scenarios. One such example is below. 

JMWE-plugin-multiple-choice-custom-field-validator 

In my experience, the appfire team, and other community members are quite helpful with JNWE scripts. Hopefully one such individual will jump in here with an exact answer.

in the meantime, if you figure it out, please do post the exact script that you used as it will help others in the future.

Thank you very much for your support, @Jack Brickey .

In this short span of time my problem has already been solved.
