Hi Andi (and others),
I can finally report some moderate success and at least I have a workaround
(hack).
Tracing the class-loader information shows that "SchemaGlobalElementImpl" isn't
being loaded and the CTTable$Factory fallback is used instead.
I don't understand why this happening, but just try to deal with the result.
Rather than patching up the XmlObject in the XSLFTable constructor, I've taken
the easier route of fixing the graphical frame to have the correct table
contents, and calling this fix before writing out the presentation contents.
Until the underlying problem gets solved, the following workaround code can be
used by any others with a similar situation.
Cheers,
/mark

involved (eg, StarMacro).
