------------------------------------

Thanks for your help!  Got to the bottom of it! See my PR and I think all our 
integration tests are passing again!

 

[https://github.com/primefaces/primefaces/pull/10759]

 

Basically had to get rid of our Wrapper as it was not doing anything and extend 
PartialResponseWriter directly. Then I had to make our CSPPartial extend our 
PrimePartial so `endDocument` was called correctly.

> Per BalusC:
> Since JSF 2.3 the default constructor of {{FacesWrapper}} subclasses has been 
> deprecated in order to force implementors to instead use the constructor 
> taking the wrapped instance (and to raise their awareness), so that logically 
> the inherited {{getWrapped()}} method will be used throughout the 
> implementation instead of the local {{wrapped}} variable. This will ensure 
> that the correct implementation is returned and correct behavior is performed 
> might the {{FacesWrapper}} implementation itself being wrapped by yet another 
> {{FacesWrapper}} implementation further down the chain. Because, when the 
> {{FacesWrapper}} implementation incorrectly/accidentally uses the local 
> {{wrapped}} variable instead of the {{getWrapped()}} method, then that other 
> {{FacesWrapper}} implementation will basically be completely ignored, hereby 
> breaking the decorator pattern.
