Hello!
Go and check out the paramter element:
http://tapestry.apache.org/tapestry4/UsersGuide/spec.html#spec.parameter
You create your components by creating jwc and html files. And you add a
parameter information to your CustomTd.jwc file:
<parameter name="value" required="yes" />
Now you can access this parameter as a property using the same name in
your CustomTd component:
<td><span jwcid="@Insert" value="ognl:value.foo">foo</span></td>
And in your CustomTr you add your td like this:
<tr jwcid="[EMAIL PROTECTED]">
<td jwcid="[EMAIL PROTECTED]" value="ognl:foo.bar">...</td>
</tr>

Hello everybody,
I'm new in Tapestry and, in fact, my boss asked me to try Tapestry
to be
able to compare with Struts in term of development time,
efficiency, etc
etc... yes, we are going to replace our old GUI web layer ;-)
Anyway, I have a question maybe you will be able to answer :
I would like to know how I could render a component, for example a
list of
custom <td ...></td> inside a custom <tr...></tr> component.
<table>
<tr jwcid="[EMAIL PROTECTED]" ...>
<td class="myTdClass">Something here</td>
<td class="mySecondTdClass" >Something else here</td>
<td jwcid="[EMAIL PROTECTED]" ...>Placeholder #1</td>
<td jwcid="%remove%" ...>Placeholder #2</td>
<td jwcid="%remove%" ...>Placeholder #3</td>
</tr>
</table>
So I want to be able to render something like that. CustomTr is
aware it
needs CustomTd and should pass some parameters to CustomTd.
CustomTd is a component which need some parameters to be render.
And I can imagine I could have another component CustomTr2 capable
to nest
the same CustomTd.
My problem is the way to defined and declare them. Is it possible
to create
only one template, a page template to define this sort of "nested
component"
or do I have to ask the web-designer to create another template for
the
CustomTd component as well?
I found how to create one component but not how to create a nested
component
and to pass parameters from the "parent" to the "child".
The main question is in fact, how to create nested component that need
parameter from the parent?
Thanks a lot
BW
