Primary Pages 5 Mobile page prependId

I am using Primefaces 5 Mobile and trying to make a spring security login page. To do this, I set a form containing username and password input fields to prependId = "false".

This, however, didn't work. Upon further research, I noticed that the id <pm: page> I wrapped everything up by adding children. Is there a way to disable this, similar to forms (prependId = "false" doesn't work here).

thank
