When returning to a partially edited Mobile Page via CSJS either with location.href="#user" or a cancel button, all data from the Mobile Page is lost. You can test it with the Mobile Value Picker project on OpenNTF, using any of the CSJS examples. http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=Mobile%20Value%20Picker

It works as expected in 853.20120320-1003. I haven't tried 8.5.2.201204171332NTF.

It appears to be overriding the setting of resetContent="false" on the user Mobile Page.
