If you're right, I'd expect the following expression make friendEmail
required when the "friend" reason is checked (it's a radio button):
reason == 'friend' and friendEmail != null
However, if I check friend and don't fill out the e-mail address, it still
passes validation. Based on the error message I'm getting in my logs (see
below), I'm guessing that I need to do some sort of "friendEmail != null"
check, but I'm already doing that.
WARN - FieldExpressionValidator.validate(80) | Got result of null when
trying to get Boolean.
Here's my full validation rule:
<field name="friendEmail">
<field-validator type="fieldexpression">
reason == 'friend' and friendEmail != null
<message>Please provide your friend's email</message>
</field-validator>
</field>
Thanks,
Matt
