Probable zone update bug

Hi All,

A colleague of mine has discovered an anomaly with the the latest t5 snapshot, it came up from April 23's nightly build jars. Here's a simple example where this happens. If the action link is moved anywhere above the t:zone in the .tml it works. If it is below the zone it does not work.

Java file:
public class Zones
{
    @Persist
    @Property
    private int data = 0;

    @Inject
    private Block someBlock;

    @OnEvent(component = "theLink")
    Object onEvent() {
        return someBlock;
    }
  
    void onAction() {
        data++;
    }
}



tml file:

<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
    <head><title>Ajax test</title></head>
    <body>  
  
    <t:zone t:id="zoneToUpdate">
        <t:delegate to="block:someBlock" />
    </t:zone>
  
    <t:block t:id="someBlock">
        <t:actionlink t:id="theLink"
t:zone="zoneToUpdate">click</t:actionlink>  
        <br/>
        ${data}
    </t:block>

    </body>
</html>


It appears as if Zones are not properly linked in some cases. The Tapestry.linkZone javascript function, 2nd line (var zone = $(zoneDiv).zone) returns undefined.
