[jira] [Updated] (TAP5-2500) Label broken when inside zone and attached to a Field after that zone

["I D (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TAP5-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

I D updated TAP5-2500:
----------------------
    Description: 
This is just one example, since the same problem is observed for TriggerFrament inside a zone when used in conjunction with a FormFragment outside the zone (and after it).

{code:xml}
    <t:zone t:id="myZone">
        <t:label for="myField">Label</t:label>
    </t:zone>
    <t:textfield t:id="myField"/>
{code}

The reason this doesn't work is because Label.updateAttributes() uses @HeartbeatDeferred and assumes this invocation will be deferred until the end of the *page* render. Alas, since the label is inside a zone, which for some reason starts and ends its own heartbeat (nested within, and occluding, the page heartbeat), the invocation is deferred only until the end of the *zone* render, i.e. - too early.

Apparently this bug was introduced in [this commit|https://github.com/apache/tapestry-5/commit/cc6fe5f3f85001eca4e0aa6a79c3bedc3e36b82c], which in turn was addressing [TAP5-940|https://issues.apache.org/jira/browse/TAP5-940].
