After 4 hours of banging my head against the wall, I figured it out:
<component id="usernameField" type="TextField">
<binding name="value" value="user.username"/>
<binding name="validators" value="validators:required"/>
<binding name="displayName" value="message:user.username"/>
</component>
I had:
<component id="usernameField" type="TextField">
<binding name="value" value="user.username"/>
<binding name="validator" value="validators:required"/>
<binding name="displayName" value="message:user.username"/>
</component>
validator vs. validators. IMO, Tapestry/Hivemind should thrown an
exception when you try to bind a name to a property that doesn't
exist. Spring does this.
