I'm trying to figure out a way to make both the Parent and Child options required for a cascade field. The exception to the rule is if they select "Other", then there is no child option needed/available.
I haven't been able to find anything in documentation or online on validating values for cascade fields using JSU. I am testing JSU on trial, the only way I see possible is using java regular expression but do not know how to set a regular expression for cascade values.
