Based on your question(s), it sounds like you you've done stuff like this
the before with struts or some equivalent. Thankfully, tapestry is much
easier.
Try not to think to of it as passing parameters to the inner list. All the
public properties of the object iterated over in you parent loop are
available within the nested loop. The example below is a bit dumb because
it just repeats the artist's name within the nested loop after each
painting, but it shows how to do what I think your asking.
.html:
<!-- parent loop -->
<span jwcid="artists">
<span jwcid="artistName"></span>
<!-- child loop -->
<span jwcid="paintings">
<LI><span jwcid="paintingTitle"></span>,
<span jwcid="artistName"></span>
</span>
<!-- end child loop -->
</span>
<!-- end parent loop -->
.page/.jwc:
<component id="artists" type="Foreach">
<binding name="source" expression="artistList"/>
<binding name="value" expression="artist"/>
</component>
<component id="artistName" type="Insert">
<binding name="value" expression="artist.artistName"/>
</component>
<component id="paintings" type="Foreach">
<binding name="source" expression="artist.paintingArray"/>
<binding name="value" expression="painting"/>
</component>
<component id="paintingTitle" type="Insert">
<binding name="value" expression="painting.paintingTitle"/>
</component>
.java:
private List artistList; // assume this exists
public Artist artist; // iterator placeholder object
public Painting painting; // iterator placeholder object
Also, have a look at the component reference. It has some really good
examples.
Cheers,
Eric
