Hi I think that this can be very useful in conjunction with PPR. In this way one could define an outcome that was just a Clay component, where the component was not a complete page, but a pagefraction. It would then be very easy to use Ajax to put that into the div's innerhtml because it would(should) be a complete component body. There might be implications regarding state that I don't see though.

In fact it would live side-by-side 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 > Is the html dynamic or static? > The content of snippet.html would be dynamic.

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. > > Or, are you looking at the Clay runtime options using the > shapeValidator callback and you would like to load html fragments? > 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. > > > Doing the above means the HTML style agency will still be > able to edit > > the HTML look and feel without me having to edit the Java > code for them. > > What part of the java code are you talking about? 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 to avoid reloading the page or sending a full tree > view that can > > just be unfolded as the page size would then be potentially > very large. > > > > Is this possible?

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. > > > > Cheers, > > Ian. > > > > Gary > > > > > > > * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * This email with attachments is solely for the use of the individual or entity to whom it is addressed.
