RenderBlock / ValidField Labels

[Mi...@expeditors.com]

Ok, so I've headed down the RenderBlock path for dynamic components.  I'm 
getting some success, and I'm beginning to see the light, but I'm not sure 
how to handle the issue of setting the label for a ValidField.

How do you change the label?

In my page's .java file I have a method that returns the block that should 
be displayed:

  public Block getBlockFromList()
   {
      Block b = null;
      ValidField vf = null;
      if (forWhateverReason)
      {
         b = (Block) getPage().getComponent("DynTextfieldBlock");  // set 
block to use
         vf = (ValidField) getPage().getComponent("DynValidfield"); // can 
get valid field assoc with block

         // what do I do here to change the label?
         // the label's value will be read from the db here.....

      }
 }

.page
    <component id="formComponent" type="RenderBlock">
         <binding name="block" expression="getBlockFromList()"/>
        </component>
 
    <component id="DynValidfieldBlock" type="Block">
        </component>
 
.html
        <span jwcid="DynValidfieldBlock">
           <span jwcid="DynValidfieldLabel"/><span jwcid="DynValidfield"/>
        </span>

suggestions?

Thanks,
