inject component from parent component

Hi 

With the annotation @Component I can inject components which are defined in the component's template, for example:
@Component(id="myComponent")
private ActionLink link;

Is there a way to inject a component from the parent component? Something like:
@Component(id="../myComponent")
private ActionLink mark;

Thank you
chris

myZone.clientId is null until Zone.beginRender is called. If
<t:yourcomponent> is rendered before the zone then zoneid will be
null.

Re: inject component from parent component

Posted by Howard Lewis Ship <hl...@gmail.com>.

The Zone is just a component:

MyPage.java:

  @InjectComponent @Property private Zone myZone;

MyPage.tml:

  <t:yourcomponent zoneid="myZone.clientId" .../>

This passes the client element id of the Zone to your component.
Alternately, you could pass the Zone itself (so that an ActionLink
inside YourComponent could return zone.getBody() to re-render the
Zone).

You should reconsider your design. Why don't you handle the ajax request in
the same component where the zone is defined?

This is definitely a bad solution. You should not do it.

Re: inject component from parent component

Posted by Josh Canfield <jo...@gmail.com>.

> I'm not sure how I can pass an embedded zone in the template as a parameter.

It sounds like what you are trying to do is have your inner component
render a block into a zone in the parent. What I would do is have the
page tell your inner component which block to render, and what zone to
update. If you want to change a value in the block then you are also
going to have to pass that value into your inner component.

Here is a really simple example:

/**
 * Simple page class, contains a value that is rendered in a zone so
it can be updated
 */
public class AjaxPickedPage {

    @Property
    private String _value;

    @Property
    @Component
    private Zone _pickedZone;
}

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd">

<body>
<t:ajaxpicker t:id="picker" zoneId="pickedZone"
renderBlock="pickedZone.body" t:value="value"/>

<t:zone t:id="pickedZone" id="pickedZone"> <!-- use both t:id and id
to make sure the zone id is fixed so you can safely pass it around -->
    <t:ajaxpicked t:id="picked" t:value="value"/>
</t:zone>

</body>
</html>

/**
 * component class which takes handles a "pick" event to update the
"value" parameter. The event returns the block Parameter, which does
something with the "value". The passed "zoneId" is used to tie the
template generated EventLink components to a zone in the page.
 */
public class AjaxPicker {

    @Parameter
    private String _value;

    @Parameter
    @Property
    private Block _renderBlock;

    @Parameter(defaultPrefix = "literal")
    @Property
    private String _zoneId;

    @Inject
    private ComponentResources _resources;

    public Block onPick(String value) {
        _value = value;
        return _renderBlock;
    }

}

<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd">

    <t:loop source="1..5" t:value="var:value">
        <t:eventLink event="pick" context="var:value"
zone="prop:zoneId">${var:value}</t:eventLink>
        <br/>
    </t:loop>

</t:container>

/**
 * Renders a "value" parameter passed in by the container.
 */
public class AjaxPicked {

    @Parameter
    @Property
    private String _value;

}

<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd">

    This is the value! ${value}

</t:container>

This is an old thread but REALLY thank you all for the concepts you

Re: inject component from parent component

Posted by Geoff Callender <ge...@gmail.com>.

It's best that the component knows nothing of what's around it. Instead, have it trigger an event to bubble up to its container and let the container decide what to do with it. Perhaps this example will help?
