Hi
I tried to perform a partial page refresh with tapestry5 and ajax... I used
the following code piece Kris Marinkovic postet on the mailing-list a month
ago... Everything works fine, except if I try to render a component, which
is not surrounded by a form-tag. Then it says:
org.apache.tapestry.ioc.internal.util.TapestryException: No object of type
org.apache.tapestry.services.FormSupport is available from the Environment.
Available types are org.apache.tapestry.MarkupWriter,
org.apache.tapestry.PageRenderSupport,
org.apache.tapestry.ValidationDecorator, org.apache.tapestry.dom.Document,
org.apache.tapestry.internal.services.DocumentScriptBuilder,
org.apache.tapestry.services.Heartbeat.
The code of the component looks like that:
....
// to retrieve page instances
@Inject
private RequestPageCache _cache;
// returns markupwriter
@Inject
private MarkupWriterFactory _mwf;
// sets the environment
@Inject
private PageRenderInitializer initializer;
public Object onActionFromUpdateLink()
{
MarkupWriter markupWriter = _mwf.newMarkupWriter();
initializer.setup(markupWriter);
Page page = _cache.get(pageName);
ComponentPageElement element = page.getRootElement();
for(String id : elementId)
element = element.getEmbeddedElement(id);
RenderQueueImpl queue = new RenderQueueImpl(page.getLog());
queue.push(element);
queue.run(markupWriter);
initializer.cleanup(markupWriter);
return new TextStreamResponse("text/html",
markupWriter.toString());
}
....
There has to be an easy solution to that problem, but I just dont get it...
Regards,
Klaus
