It looks like you're creating a custom component called Person. Is
that what you want to do? Or is Person one of your domain classes
with first name, last name, etc. I also don't understand doing
instanceof. You should make absolutely sure that your page's property
called "Persons" always contains a Collection of instances of type
Person.
If you rename your Persons property to people, which is more in line
with Tapestry convention and avoids confusion with what I assume is a
domain class Person, how about this code:
<span jwcid="@Foreach" source="ognl:people" value="ognl:current">
<span jwcid="@Insert" value="ognl:current.name" />
<ul>
<li jwcid="@Foreach" source="ognl:current.addressList"
value="ognl:currAddr" element="li">
<span jwcid="@Insert" value="ognl:currAddr.address"></span>
</li>
</ul>
</span>

Hi @ All....
I?ve try to build a page but i?m not right in understanding how tapestry
works....
OK: I Have a Page Class "Context" (extending BasePage implementing
PageBeginRenderListener)which consists some propertys of Type "Persons"
which extends from BaseComponent and which ist not abstract. This Class
builds an arraylist of "Person" extending BaseComponent.
Now I want to initialiaze the Propertys in the Context Class at the begin of
pageBeginRender is called. There i create a new Instance of Persons. then i
call persons.setPersonList(ArrayList Person) so that all value are
initialized.
In the Context.html i try to visualize the Context builded when
pageBeginRender is called.
<span jwcid="@Foreach" source="ognl:Persons" value="ognl:ListItem">
<span jwcid="@If" condition="ognl:ListItem instanceof
Persons">
<span jwcid="@Person"
AdresslList="ognl:ListItem.getAdressList()"
Name="ognl:ListItem.getName()"/>
</span>
</span>
The Class person has the propertys: String name and ArrayList AdressList.
So the Problem is that the parameter are not referenced. the component
parameters are always null... or in detail they have the values defined in
the standart constructor. Can anyone help me... ?!???!?!?!?
