Tapestry5 Dynamics Parameter Binding

Hi

I have two components on a single page and I want a property of one
component to be bound to parameter of another component.
I can easy do that in a page but can I do that using
ComponentClassTransformWorker.

tml is like

<t:component1 t:parameterToBeBound='propertyFromComponent2'/>
<t:component2 />

Java Class is

public class Page {
   @Component
   private Component2 component2;

   public String getPropertyFromComponent2(){
      return component2.getPropertyFromComponent2();
   }
}

What I want is

<t:component1/>
<t:component2 t:attached='component1'/>

Everything else happens Auto-ComponentClassTransformWorker-matically



I think I should be able to but am sure how ?

regards
Taha

Have you tried putting the @Property tag on your Component1?

public class Page {
  @Component
  @Property
  private Component1 component1;
}

<t:component1/>
<t:component2 t:attached='component1'/>

Assuming component2 takes a parameter named "attached" with default binding
as property and an appropriate type to accept component1...

I haven't run this code, but I believe it should work...
