Re: Further suggestion please?]

Hi Damar,

Glad you figured things out :-)

BTW, you might be interested in something David Li posted to the XMLC list.

http://xmlc.enhydra.org/project/mailingLists/xmlc/msg02204.html

Basically, you can use a new feature added to XMLC-2.2alpha2 (current 
release is alpha4) in XMLCContext where you can quite simply load plain 
html files at runtime and it will give you a Document object.  This might 
be better than having to compile headers, footers, and the like.  I haven't 
tried it yet, so you'll have to experiment.  You might also think about 
using compile-time SSI (server side includes).

Oh, and if you use BTemplate and return a node tree which contains 
BTemplate directives, those directives should also be processed by their 
respective models.  That seems like something you might run into 
here.   But seeing as you solved your issue, maybe not.  Just figured I'd 
mention it.

You can grab the XMLC-2.2 stuff from the latest Barracuda CVS or grab it at:
http://debian-sf.objectweb.org/project/showfiles.php?group_id=49

Note that the XMLC-2.2 jars in Barracuda are actually more recent than 
alpha4 and has at least one fix that is pretty important.
