The tapestry request processing pipeline is quite complicated and as you get
further down, it becomes less of a "black box" and you must know more of
it's internals ("white box"). There is a great diagram at the bottom of

This sounds like the same problem that the RenderInformals mixin has (jira
here https://issues.apache.org/jira/browse/TAP5-1918)
I wonder how many mixins suffer from this problem.

my dirty approach was to set the visibility just via a property.

Yes , you are right ,maybe using ComponentEventRequestHandler is the best
way now . But I wish that the next version of tapestry will provide some
service to render html more easily.^_^
The AjaxComponentEventRequestHandler is the key of partial-rendering , maybe
I should spend much more time to
No matter what you do, you will need a fake request and probably a fake
response. Tapestry converts components to RenderCommands but they still
point to their resources. For example, if you have an EventLink on in your
block, it requires a Request object for it to render.

Using the context attribute is the way to go. It's plain 'context' and
not 't:context', though.
The context must be a primitive (or encoded as a primitive), so I
would recommend you start by passing only the position

I would like to extend that so that a component can have several

Hi
One way would be to use Block Parameters.
(Warning: Code not tested)
public class MyLayout {
@Parameter(defaultPrefix = BindingConstants.BLOCK)
@Property
private Block myBlock;
@Inject
private Block myDefaultBlock;
Block defaultMyBlock(){
return myDefaultBlock;
}
I don't think you'll be able to pass more than one body, but your layout
component can accept any number of parameters, which can accept blocks.

Arno Haase,
Thank you for your reply.

public void onSelectedFromTopLevel(int position) {
System.out.println("Selected button item is --> " + position);

As the expection says "Property videoItem is null" and so videoItem.position
will cause an NPE.

Your encoder returns null both ways - that is probably the cause for
your NPE.
It is responsible for storing (and retrieving) the collection elements
of the loop for the time between rendering and submit - returning null

You can find some Prototype based alternatives at

I know this is a pretty old post, but had a question.

Use different methods for different fields with different logics.

So you can't dynamically get the field id's like you can in mixens with
ClientElement.getClientId and use a single method?

Yes, but if you're not in a mixin, how do you know which field we're

Yes ,that's the real question.the block/zone/component dependents on the
