tapestry 5 - How to call peekUniqueId?

[Dariusz Majewski <da...@gmail.com>]

Hi All,

    In tapestry4, IRequestCycle has a peekUniqueId method
(link<http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/IRequestCycle.html#peekUniqueId%28java.lang.String%29>).
How to achieve that in tapestry5 ?

Thanks,
Dariusz

What I was trying to achieve is to have element to trigger formInjector
above forminjector component. Finally I was able to do so by using logic
similar to Label component.

I wrote a new component:

public class FormInjectorTrigger {

    @Parameter(required=true)
    private ClientElement target;

    @Environmental
    private Heartbeat heartbeat;

    private Element element;

    void beginRender(final MarkupWriter writer){
        element = writer.element("a");
        writer.attributes("href","#");

        heartbeat.defer(new Runnable() {
            @Override
            public void run() {
                element.forceAttributes("onclick",
"$('"+target.getClientId()+"').trigger();");
            }
        });
    }

    void afterRender(MarkupWriter writer)
    {
        writer.end(); // a
    }
}

and use example is:
<t:form t:id="testForm">
    <a t:type="FormInjectorTrigger" t:id="injectorTrigger"
target="component:forminjector">Click me...</a>

    <div t:type="forminjector" t:id="formInjector" position="below"/>
    <t:block t:id="textBlock">
        <t:textfield value="stringValue"/><br/>
    </t:block>
</t:form>

inside java:
    @Inject
    private Block textBlock;

    public Object onActionFromFormInjector() {
        return textBlock;
    }

I would really like someone to comment on this. Is there an easier approach?

I have to admit I don't understand how heartbeat works. When I used
writer.attributes("onclick", "$('"+target.getClientId()+"').trigger();")
instead of element.forceAttributes these attributes where added to a form
tag.

Cheers,
Dariusz

Generally, you should wait until after a component has rendered, then
invoke getClientId() on it.
