Quite right. Sorry for being confusing. I ran into a corner case for IE6 and IE7 where postfix ++ does not always yield a number, e.g. when applied to some host objects. The comment at line 80 of http://code.google.com/p/google-caja/source/browse/trunk/tests/com/google/caja/browser-expectations.html is my best recollection. > > --Oliver > > _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
