Ok point taken, yes the HTMLResponseWriterImpl definitely is html so a
fix there is valid.

But we are talking about the HtmlResponseWriterImpl, which outputs HTML.
The fix I have done is in that class and it only checks if there is a
CDATA already started before starting one when writing the scripts. It
is slightly different to the original problem (about the HtmlResponse,
which is different from the one in Mojarra). The fix simply checks if
there is the CDATA around the script before opening another one inside
the script. I think it is OK if we just do not nest CDATAs in the HTML
response, even if it was allowed.
And this fixes the problems with PrimeFaces too, without having to
change the ResponseWriter or the PartialResponseWriterImpl...

Hia guys please also read up on my jira response.
The entire thing is not as easy as it seems, because there are
various ways a cdata block can be opened, first you can do it via
startCDATA secondly you can do it via a direct write.
I did some kind of double buffering in case of a cdata block was
opened and then escaped the ]]> as multiple cdata blocks (the jira
response explains the technique exactly)
And yes there is somewhat a speed hit because of this, but in case
of the partial response writer I did not have a chance because:
But the partial response writer is somewhat different, because it
has to press html code in a valid xml response format, so nested
cdata blocks can occur naturally, the normal response writer is
somewhat different because nested cdata blocks are only forbidden
for xmlish output dialects others might allow it.

Subject: Re: Fixing ResponseWriter.startCDATA/endCDATA
Further investigation of this incompatibility problem with
myfaces leads me to
the fact that in the HtmlResponseWriterImpl, when we write
the content of a
script, we create a CDATA element without checking if is
nested at all. That is
a problem, because if we use the standard response writer
and we write a script
section inside a CDATA section, the problem will be triggered...
We need a way in HtmlResponseWriterImpl to check nested
CDATA calls to the
startCDATA or endCDATA methods I guess.

As you can see in my black box tests with Mojarra, the
behaviour is different in
both implementations. In the base ResponseWriter class,
they don't do anything
in the startCDATA method and throw an undocumented
exception in the endCDATA.
In both implementations of the base class, they
throw an exception if the
startCDATA method is called and it had been called
already...
I don't quite understand our implementation of the
PartialResponseWriterImpl. We
do buffer nested CDATAs and write them when closing
the parent one? This would
still create nested CDATAs... I still need to
understand this bit properly,

Hi,
Having problems with Primefaces
again I have realised that something
was
working with Mojarra, but not
with MyFaces. Again, is the
ResponseWriter.startCDATA stuff
which Primefaces invokes directly on
its
main phase listener.
However, reading the javadocs:
https://javaserverfaces.dev.java.net/nonav/docs/2.0/javadocs/index.html
It says that method "should
take no action when invoked"...
which
means
that it should be completely
empty as far as I understand. If
that was
the
case, we would get the same
behaviour in both implementations...
Cheers,
Bruno
