Tapestry make Select mandatory

Question

I want to create a dropdown List with Select and I want to have a default value in it (something along the lines of "choose something").

The default I get but how do I "force" the user to choose from the select input? Should I catch it's value when I commit? Is there no cleaner way?

Answer 1

Try "validate".

Works like this:

<t:zone t:id="modelZone" id="modelZone">
         <t:if test="yourZoneTestVariable">
           <p>
              <t:select t:id="selectId" model="yourModel" validate="required"/>
           </p>
         </t:if>
      </t:zone>

Hope this helps you.
