Hi,

 

I am having problem with PPR. I want to refresh a region on the screen that
also contains plain html. In order to be able to refresh the area I simple
put all plain html in <h:ouputText> with escape="false". The wrapped html
contains also new lines. Now, every time a PPR request is made I get this
exception:

Are there any not allowed characters on <h:outputText> with PPR that cause
this problem?

 

Thanks,

Guy.

Re: [Tomahawk][Sandbox]

Posted by Ernst Fastl <er...@gmail.com>.
I haven't had this particular problem. However some time ago we had troubles
with the character encoding in PPR requests. Since then PPR tries to obtain
the character encoding from
facesContext.getResponseWriter().getCharacterEncoding().
If that fails UTF-8 is used as a default. Any characters supported by
the character
encoding should be valid.

Can you post an HTML snippet which used in an h:outputText produces this error?

kind regards

Ernst
