There are other properties with a "validity range" and a fallback
value: column-count, initial-page-number, column-number, number-
columns-repeated, number-columns-spanned, number-rows-spanned,
hyphenation-{push, remain}-character-count; only hyphenation-ladder-
count does not have a fallback value in 1.0, so maybe this was just
an oversight.
Note that the fallback value is different, in general, from the
default value, as it is derived from the illegal value by rounding.
I guess we'll have to have a look at all these properties to see how
the fallbacks are dealt with.
I remember that, when I implemented the default value for the column-
number property (+/- 2 months ago), the described fallback value in
case of zero-or-negative values wasn't provided, but the "error" (=
no error according to the Rec) was dealt with in the TableCell or
TableColumn's bind() method. I coded this functionality into
ColumnNumberPropertyMaker.get() [Didn't get around to rounding the
value in case it's non-integer, since I wasn't sure how to check for
that... there's still a TODO for that]
Anyway, it was quite straightforward to implement that logic into the
Property system.
I'm thinking that, if this is shared by a number of properties, then
the option should be investigated to abstract this out into a common
Maker for the props in question.
I'll look into this as soon as I find some spare time.
Cheers,
Andreas
