with the main page. So if I had page main.html and wanted to return
snippet.html as the response to the remoting call then I'd arrange it as
/somedir/main.html
/somedir/snippet.html

The content of snippet.html would be dynamic. In my use case I go and
get a List of extra info about an item and would want snippet.html to
render a table with a row per List entry.

Not static. I collect then want to display more data. My remoting method
gets more information then renders a dynamic document to return as the
response from the remoting method. The dynamic document displays the
extra info.

Yes, I'm trying to understand how (or if) I could use class
org.apache.shale.clay.component.Clay to process a subtree and then grab
the HTML result of that processing to return as the output of my
remoting method.

The remoting method. It generates HTML and uses a ResponseWriter to
output the HTML to the page that made the remoting call. I would like to
generate that HTML by calling Clay and having it render a sub-tree, but
I can't see how to do it or even if it can be done. Pseudo-code...
Class MyViewController extends AbstractViewController {
/**
* Called by AJAX function in page main.html
*
* Use Clay to render a dynamic snippet of HTML then return it.
*/
public void aRemotingMethod() {
// Get item id
String id =
getFacesContext().getExternalContext().getRequestMap().get("id");
// Get more detail about item with id
List<String> extraDetails = getExtraDetail(id);
/** This works, but HTML is hard-coded into the
ViewController...
String html = "<table>"
for( String detail: extraDetails ) {
html += "<tr><td>" + detail + "</td></tr>";
}
html += "</table>";
// Can I somehow use Clay here to generate HTML?
// Clay clay = new Clay();
// Need to set URL of snippet.html as view id
// Need to make extraDetail available to the processor.
Make this class
// the ViewController for snippet.html?
// Get clay to process: clay.encodeBegin()?
// Get HTML back from clay somehow once sub-tree is
created
// String html = clay.?????()
// Return HTML
writer.write(html);
getFacesContext.responseComplete();
}
}

I want the HTML fragment to be managed outside the ViewController class
code, yes. The third parties can edit snippet.html to alter the
look-and-feel.
