Need a validator that makes field Custom_Field_one required if project key = X

[Frank Racioppi]

I have a need to make a multiselect list become required if a project key =X

My plan is to use the scriptrunner validator option in the workflow transition.  

My current thought is:

if (issue.projectObject.key == 'My Project Key' &&

cfValues['Custom_Field_one'] == 'None') {

    return true

}

Note: the multiselect list cannot be set as a required field by default and therefore "none" will be an option.

Hi,

I suppose you need Behaviour script which invokes setRequired(true) for the field. See https://scriptrunner.adaptavist.com/4.3.1/jira/behaviours-overview.html#_using_a_server_side_validator_to_set_the_fix_versions_required.
