Description

Given a template with:

<t:zone t:id="testZone">
<t:delegate to="testBlock" />
</t:zone>

<t:block t:id="testBlock">
<t:zone t:id="zone1">
<t:delegate to="zone1Block"/>
</t:zone>

<t:zone t:id="zone2">
<t:delegate to="zone2Block"/>
</t:zone>
</t:block>

<t:block t:id="zone1Block">
<t:actionlink t:id="showZone2Block2" zone="zone2">show zone2Block2</t:actionlink><br/>
<t:actionlink t:id="refreshTestZone" zone="testZone">refresh testZone</t:actionlink>
</t:block>

<t:block t:id="zone2Block">
zone2Block
</t:block>

<t:block t:id="zone2Block2">
<b>zone2Block2</b>
</t:block>

and with code:
@Inject
@Property
private Block _testBlock;

@Inject
@Property
private Block _zone2Block2;

@Inject
@Property
private Block _zone1Block;

@Inject
@Property
private Block _zone2Block;

Object onActionFromShowZone2Block2()
{
return _zone2Block2;
}

Object onActionFromRefreshTestZone()
{
return _testBlock;
}

------

I can click the 'show zone2Block2' as many times as I want (at first), but after clicking 'refresh testZone' (which will refresh the testZone properly) if I try clicking either of the actionlinks I get a ComponentEventException that is expecting a regular action request return type instead of an Ajax one::

org.apache.tapestry.runtime.ComponentEventException
A component event handler method returned the value org.apache.tapestry.internal.structure.BlockImpl@38c8c5. Return type org.apache.tapestry.internal.structure.BlockImpl can not be handled. Configured return types are java.lang.Class, java.lang.String, java.net.URL, org.apache.tapestry.Link, org.apache.tapestry.StreamResponse, org.apache.tapestry.runtime.Component.
