Rails, Wicket, Grails, Play, Tapestry, Lift, JSP, Context and Click
Hi,
After read this[1] post about how to benchmark the response time and
the rendering engine of some component based frameworks, I felt
comfortable to try it with Apache Click. The example used by the
author's post uses a panel or other artifact provided by the framework
to create a reusable component.
This one[2] is my first try and I've used the filterPanel[3] as
sample, but I think I've missed something on the model setup because
the the new panel (ProductPanel) has not been rendered.
Can someone take time to look at in the source and provide some
feedback before I send it to the post's author to publish it?

I was showing that $productPanel works (while using just one Product).

And here was showing that if I use one list of product I couldn't make
it work. In this case I use a for loop to show the product in the
list: $productPanel.product($p)

I'm not sure what you are trying to achieve with the above snippet?
You are calling panel.setProduct(p)?
This call is made *after* the panel rendered via $productPanel.
setProduct adds the product to the model again? But the products are already made available to Velocity.

For some reason the panel isn't rendering when using it in velocity way:

The ProductPanel template:

In the ProductsPage we are using it:

Can't I use a component in Velocity template?

The benchmark has some requisites[1]:
<quote>
Framework features
For each framework, the page needs to use the following framework features:
-rendering of a list of products, each rendered as a custom component
so that the layout of each product can be reused on other pages. For
each product, it’s associated categories are shown.
-Separation of the page into a template that can also be used for
other pages, and the content that is unique for each page (this
content is surrounded by the template).
-Injection of the page name (including the number of products) in the
title tag, and in the master template page name.
</quote>
The final page products should look like this one:
https://github.com/jtdev/blogpost_files/blob/master/template.xhtml
The resulting page uses a product panel and the associated categories
of each product in each table row. So, I can't move all the page
template code into the panel template since it will break the rules.

Gilberto

Currently the panel is rendered and only then is products added to it. You need to swap the order
around. First add, then render.
Basically your page template should contain only: $panel
Move the page template code into the panel template, and lastly add the products to the panel inside
the Java Page. This means you populate the panel with products before rendering it.

Thinking a little more about it[1]:
<quote>
<table>
#foreach( $p in $products )
<tr>
<td>$productPanel($p)</td>
<td class="categories">
#foreach( $c in $p.categories )
#if ($foreach.count>1),#end $c.name #end
</td>
</tr>
#end
</table>
</quote>
I guess it can't work because the panel component can't be used in the
loop. I would need a repeatable panel in this case, right?
