Josh Canfield commented on TAP5-1445:
-------------------------------------

As Howard said, this can be accomplished today. You are confusing "t:id" with the parameter "id", which is understandable. The parameter "id" does what you want.

This example code works today:

**** TML ***

<t:loop source="1..5" value="zoneId">
    <p>
        <t:zone t:id="myZone" id="hello_${zoneId}">
            Hello! ${zoneId} ${now}
        </t:zone>

        <t:eventlink event="refresh" t:context="zoneId" t:zone="hello_${zoneId}">Refresh</t:eventlink>
    </p>
</t:loop>

**** PAGE ****

    @Property
    private Integer zoneId;

    @Component(id = "myZone")
    private Zone zone;

    public Block onRefresh(Integer zoneId) {
        this.zoneId = zoneId;
        return zone.getBody();
    }

    public String getNow() {
        return new Date().toString();
    }

*** GENERATED HTML ***

<p><div class="t-zone" id="hello_1"> 
Hello! 1 Wed Feb 16 08:48:35 PST 2011
</div>
<a id="eventlink" onclick="javascript:return Tapestry.waitForPage(event);" href="/test:refresh/1">Refresh</a>
</p>
<p><div class="t-zone" id="hello_2"> 
Hello! 2 Wed Feb 16 08:48:35 PST 2011
</div><a id="eventlink_0" onclick="javascript:return Tapestry.waitForPage(event);" href="/test:refresh/2">Refresh</a>
</p>
<p><div class="t-zone" id="hello_3"> 
Hello! 3 Wed Feb 16 08:48:35 PST 2011
</div><a id="eventlink_1" onclick="javascript:return Tapestry.waitForPage(event);" href="/test:refresh/3">Refresh</a>
</p>
<p><div class="t-zone" id="hello_4"> 
Hello! 4 Wed Feb 16 08:48:35 PST 2011
</div><a id="eventlink_2" onclick="javascript:return Tapestry.waitForPage(event);" href="/test:refresh/4">Refresh</a>
</p>
<p><div class="t-zone" id="hello_5"> 
Hello! 5 Wed Feb 16 08:48:35 PST 2011
</div><a id="eventlink_3" onclick="javascript:return Tapestry.waitForPage(event);" href="/test:refresh/5">Refresh</a>
</p>

>                 URL: https://issues.apache.org/jira/browse/TAP5-1445
>             Project: Tapestry 5
>          Issue Type: Improvement
>          Components: tapestry-core
>    Affects Versions: 5.2.4
>            Reporter: Denis Stepanov
>            Assignee: Howard M. Lewis Ship
>            Priority: Minor
>
> It will solve dynamic zone id problem, when clientId is null it will use the previous approach. Now we are forced to have a copy of the zone component with a similar solution.
> Also, it would be nice if a generated id is available before rendering, in a case when someone calls getClient on a zone before it have been rendered.
