Conditional transition based on field value

[Ofer Prat]

Hi there! I want to provide the following workflow:

When resolving a bug I am displaying a screen to collect info about build, resolution, and comment.

I want to add a field there to collect info about customer interaction, and I want this field to be mandatory if the bug was reported by a customer (this can be determined by another field - "Origin").

So basically I want a field to be mandatory based on the value of another field.

Suggestions how to implement? Thanks!

I see this has been asked and answered multiple times (e.g. here: https://community.atlassian.com/t5/JIRA-questions/Can-we-set-a-custom-field-as-mandatory-based-on-other-custom/qaq-p/453608)
