Question

I want to branch if a message-property-code does exist or not.

<g:if test="${message(code: 'default.code.foo')}">
  true
</g:if><g:else>
 false
</g:else>

should answer true if there a message property named default.code.foo and false if not.

It fails because it answers the code if there is no property for it.

Answer 1

Can’t you supply a default that’s a blank string?

<g:if test="${message(code: 'default.code.foo', default:'')}">
  true
</g:if><g:else>
 false
</g:else>

This will equate to false under Groovy’s truth
