i use the "KeepTogether" and it does not really work. first i tried to
have a "KeepTogether" with two flowables inside. the first one was again
a "KeepTogether" (with two paragraphs inside) and the other one was a
paragraph. well ... the output was not what i wanted. hard to describe,
sorry. but the "KeepTogether" flowables did not span the correct area.
it looks like that after nested "KeepTogether" blocks there is _always_
so i made no nested "KeepTogethers". but now i have circumstances where
i get a "LayoutError". the problem here is that i use styles with a
as you can see in the "_add" method of the "Frame" class the calculation
of the required space uses the "spaceBefore" setting but not the
BUT: at the end of the method the current y-position is decreased by the
value of "spaceAfter" and sometimes it happens that the value of "y" now
is negative! the "_add" method itself returns 1 so it signals not to
make a framebreak and now .... the nightmare starts :-). the next
flowable which should be layouted crashes with a exception.
i changed my styles not to use "spaceAfter" anymore. now i work with
"spaceBefore" (and a few more styles) and everything works. but it would
be a good idea to rework the code.
