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].
