Upgrading from R_1454 to R_1600

I'm trying to upgrade from R_1454 to R_1600. With 1454, I had a JSF dataTable that used a commandLink to edit a record. This command link would submit a JavaScript form. For some reason, this is no longer working with R_1600. There's no error or anything, it just never makes it to my edit page. Any ideas?

The content of the generated HTML hasn't changed.

Thanks,

Matt
