Re: defered parsing for WML and xHTML - Enhydra tests

Hi Sinisa,

Can you provide a copy of your options.xmlc that you are using?

Also, not having looked over the stack trace extensively, here are a couple 
of interesting things to note about deferred parsing...

1.  classes not compiled with deferred parsing support are able to be 
loaded by XMLCDeferredParsingFactory, but not converse is not 
true.  XMLCStdFactory cannot load classes compiled for deferred 
parsing.  Assuming there aren't extra bugs in deferred parsing (we'll 
figure that out and fix them if there are any), you should use the 
DeferredParsingFactory to load XMLC classes in all cases and never again 
bother using the XMLCStdFactory.

2.  When classes are compiled for deferred parsing, the generated .xmlc 
files and the source files need to be available to deferred parsing for 
loading at runtime (unless you are loading directly from a file instead of 
a pre-compiled class).  This is because deferred parsing doesn't store all 
the extra information in the class that normal XMLC compilation does (which 
gets around bugs with loading huge classes in certain VM's).  You should 
always copy the generated.xmlc files and the source files to the same 
location as the generated .class files so that these can be picked up from 
the classpath.  You can also override the resources on the classpath by 
providing configured resource dirs for loading the resources.  That way, 
you can have a place to modify these files at runtime where the changes 
will be immediately picked up by deferred parsing, in which case deferred 
parsing will reload the template and you will immediately see the result at 
the next loading of the class associated with that file.

If you have questions about this stuff or other issues about deferred 
parsing, let me know.  In the mean time, I will take a look at the stack 
trace and see if I can determine what is happening.  Make sure to let me 
know if one of the two notes above about deferred parsing provides 
information to fix the issue for you.  If so, then no effort debugging will 
be necessary (that would be nice!).
