Hello,
When you use a dataView control in a mobile App and you show data from another database, the transition to another "view" (a different page in the mobile app) doesn't work. I get the message

If the data is in the same nsf as the mobile XPage app everything works fine.
By the way, I've reconfirmed that the dataview control has an attribute pageName="documentPage" and that a <xe:appPage id="appPage3" pageName="documentPage"> also exists.
