> Key: TAP5-290
> URL: https://issues.apache.org/jira/browse/TAP5-290
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.15
> Reporter: Hugo Palma
> Assignee: Howard M. Lewis Ship

> I have a zone that contains two components in its body that i'd like to update on a given event.
> Because i can't return more than one component to update from the event listener method i created a block inside the zone and outside the two components and now return the block from the event listener method. Something like this:
> <t:zone>
> <t:delegate to="myblock"/>
> <t:block>
> <t:component1>
> ...
> </t:component1>
> <t:component2>
> ...
> </t:component2>
> <div>whatever</div>
> </t:block>
> </t:zone>
> I use the delegate to because i want the block content to be visible when the whole page is rendered and not just after the update event.
> So, the page renders just fine. But, when the event is executed i get the following error logged and nothing is updated on the UI:
> [ERROR] TapestryModule.RequestExceptionHandler Processing of request failed with uncaught exception: Namespace prefix for URI 'http://www.w3.org/1999/xhtml' is not defined.
> java.lang.RuntimeException: Namespace prefix for URI 'http://www.w3.org/1999/xhtml' is not defined.

> at org.apache.tapestry5.internal.services.PageRenderQueueImpl.renderPartial(PageRenderQueueImpl.java:150)
> Although the block rendered fine the first time it seems to fail to render upon the partial-update. After some digging i found out that the only way that i could get this to work was to only include tapestry namespace tags inside the block. So if i have something like:
> <div>whatever</div>
> inside the block i get the error. But if i change it to:
> <t:any element="div">whatever</t:any>
> it works just fine.
> Again, the exact same block renders just fine when the page loads.
