Upgrade issues with 5.0.15

[Blower, Andy]

We've just tried to upgrade our project from 5.0.14 to the new 5.0.15 release 
of Tapestry and have discovered a couple of problems.


1)      Our custom binding 'fmtmessage' stops working with .15, the 'fmt' part 
is ignored and the standard 'message' prefix is used with the output prefixed 
with 'fmt'.

2)      Our custom XhtmlMarkupWriterFactoryImpl to enforce valid XHtml output 
also seems to have stopped working.

Anyone else had these issues with 5.0.15?

They are configured like this in our module:

public static void contributeAlias(Configuration<AliasContribution> 
configuration, @InjectService("XhtmlMarkupWriterFactory") MarkupWriterFactory 
factory)
{
      configuration.add(AliasContribution.create(MarkupWriterFactory.class, 
factory));
}

public static void bind(ServiceBinder binder)
{
      binder.bind(MarkupWriterFactory.class, 
XhtmlMarkupWriterFactoryImpl.class).withId("XhtmlMarkupWriterFactory");
}

public static void contributeBindingSource(MappedConfiguration<String, 
BindingFactory> configuration, BindingSource bindingSource)
{
      configuration.add("fmtmessage", new 
FormatMessageBindingFactory(bindingSource));
}
