Re: T5: Using the strategy pattern with components.

Is there a way to get a reference to a component (or block) by classname
(MyComponent.class), instead of the id?  I tried out the approach Thiago
suggested, and it works fine.  However, it requires me to keep a page with a
catalog of components around (not the end of the world, but inconvenient).

Any suggestions?

Thanks!


PS: Here's code for the approach Thiago suggested:

Container.java:
    public Object getTheComponent ()    {
        org.apache.tapestry5.runtime.Component component =
componentSource.getComponent("Catalog:component1");
        return component;
    }

Container.tml:
<html t:sidebarTitle="Framework Version"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd" >
    <t:delegate to="theComponent"/>
</html>

Catalog.tml:
<t:block>
    <t:component1 t:id="component1"/>
</t:block>
