E.g. the one for Writer TextFrames:

You could try to see which C++ class implements the setPropertyValue()
member function handling your WritingMode. Perhaps as a start, log the
value of rPropertyValue in SvxShape::setPropertyValue(). If you see
WritingMode there, then you can step in the debugger to see where is
that handled. Possibly the trouble is that we have text::WritingMode and
text::WritingMode2, and these are all sal_Int16 values so implicit
conversion between the two groups is allowed. This means if you write
the value as text::WritingMode2 and later you read it as
text::WritingMode, you won't get a build-time error for that.
