Since there are 2 patch files, I don't know what gonna happen if I install Formulize on 2.0.16.

Yes! Formulize 2.2 RC1 is compatible with XOOPS 2.0.16. I'm currently running that together with Registration Codes 2.2 RC1, they work well. Before, I was using XOOPS 2.0.15 which had some major bugs that Formulize 2.2 RC1 ran into problems.

class\xoopsform\formtextdataselect.php
As for these 2 patch files, I think the URL below can help answer your question:
http://sourceforge.net/tracker/?func=detail&aid=1077123&group_id=41586&atid=430842

Please contact Julian Egelstaff directly for further details.

Anyway, I didn't make use of these 2 patch files, and Formulize 2.2 RC1 just works fine in meeting my needs.

I hope this helps.
