jsf - PrimeFaces TypeError: PF(...) is undefined

I followed the DataTable Filter showcase from PrimeFaces on my own DataTable. Every time the "onkeyup" event occurs I get a

TypeError: PF(...) is undefined error in Firebug and a "Uncaught TypeError: Cannot read property 'filter' of undefined

in Chrome Console. The filtering does not work.

Here is my XHTML page:

In my case, I found that my TypeError: PF(...) is undefined error (without the additional property error) was caused by Primefaces not being able to find the widget widgetVar="usersTable" for example because of a spelling error

In this case, the console output right above the error in Firebug gives you the explanation Widget for var 'editExecContactDialogg' not available!
