[Sugar-devel] Sugar-devel Digest, Vol 10, Issue 16

[Jim Simmons]

Sumit,

I had a similar problem in Read Etexts and ended up solving it using a
similar approach to what you are proposing.  I wanted my Activity to
save and restore the current page number.  I ended up putting the page
number, preceded by a "P", at the end of my title.  I used the "P" so
that titles that ended in numbers could be distinguished from titles
that ended in a number (1984, for example).

I would not use either of the tags you are proposing to use, because
they *are* used by Sugar.  You might put a code at the end of the
title like I do, or you might put something in the "tags" or
"description" fields, which can be modified by the user but most of
the time probably are not.

.84 solves the problem you refer to.
