Approaching ga-ga point on 3.0

["F. Da Costa Gomez" <dc...@fixed.com>]

Following the part of a component spec that worked perfectly fine in 2.4-a5.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE component-specification PUBLIC "-//Apache Software 
Foundation//Tapestry Specification 1.4//EN" 
"http://jakarta.apache.org/tapestry/dtd/Tapestry_3_0.dtd">

<component-specification 
class="net.sf.tacos.tree.components.CTreeNodeView" allow-body="yes" 
allow-informal-parameters="yes">
    <parameter name="closeNodeImage" type="org.apache.tapestry.IAsset" 
required="no" direction="in"/>
    ...
</component-specification>

File is properly validated by the XML validator in Eclipse 2.1.

In 3.0 it throws the error seen below.
Normally this means a typo or the name was not changed after moving a 
class. None of that happened.
The component was also defined properly in the .app file.

net.sf.tacos.tree.components.CTreeNodeView is absolutely there, no 
question about it.
Nothing changed in the spec other than the 3.0 stuff. :-(

Any help greatly appreciated
TIA
