Component Event Context, ValueEncoder & Lifecycle

[Stefan]

Hi,

i'm currently writing my first component, which should work like this one : http://wiki.apache.org/tapestry/Tapestry5HowToCreateASimpleGraphComponent

Everything works fine so far, but:


doing so:

In the page template:
<t:myComp context="myDataStructure" />

In the components beginRender method:
void beginRender(MarkupWriter writer) { 
        Link lnk = resources.createEventLink(EVENT_NAME, context);
        

        writer.element("embed", "type", "image/svg+xml", "width",
                                width, "height", height, "src", lnk);
        resources.renderInformalParameters(writer);
}

And at least, the corresponding action:
public StreamResponse onRenderGraph(Object... params) {
        // the params object now should be the passed myDataStructure
        //... rendering stuff
}


This works fine so far, but some things are too unclear to me:
the generated eventlink looks horrible:

Is there a way to use a custom ValueEncode to generate a better url?
I do not want to provide my package structure to the client ;)

And, more important to me is to know something about the lifecycles.
How long and "where" life these "passed objects"?

Thanks,
Stefan

I have to pass some complex data structures (encapsulated in objects) to the component, // should render this: <embed type="image/svg+xml" src="..." width="280"height="280"> "/somepage.component.action/org.localhost.something.package.MyStructure $12345"
