Rewind Question

[D&J Gredler]

I'm having some rewind trouble...

I have a custom component (call it a "Foo") which contains a Form. This
"Foo" component has a required parameter (call it "baz"). Furthermore, this
"Foo" component contains a For component (inside the Form) whose "source"
parameter is a method call whose return value depends on "Foo.baz". The page
that contains the Foo component renders fine. However, during the rewind
phase, Tapestry tries to loop through this For component, thus calling the
method bound to its "source" parameter. That's fine, but said method depends
on the "Foo.baz" required parameter, which at this point is null for some
reason.

Does anyone have any advice??

Some code:

<component-specification class="Foo">
   <parameter name="baz" required="true"/>
   ...
   <component id="for" type="For">
       <binding name="source" value="getProperties( )"/>
       ...
   </component>
   ...
</component-specification>


public abstract class Foo {
   ...
   public abstract Object getBaz( );
   public abstract void setBaz( Object baz );
   ...
   public List getProperties( ) {
       Defense.notNull( getBaz( ), "baz" );
       ...
   }
   ...
}
