Brian Leathem commented on RF-13221:
------------------------------------
[~jtrantin] have you tried reproducing this with _vanilla JSF_? ie. remove all
references to RichFaces from the project, and see if you get the same
behaviour. This will help us narrow down if the problem is in RichFaces or in
JSF.
> Incorrect XML encoding in AJAX response
> ---------------------------------------
>
> Key: RF-13221
> URL: https://issues.jboss.org/browse/RF-13221
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 4.3.4
> Reporter: Jonáš Trantina
>
> Consider the following example:
> {noformat}
> <h:form>
> <a4j:commandButton render="@form" value="rerender me"/>
> <script src="path_to_some_script?param=asd&important=param"></script>
> </h:form>
> {noformat}
> when commandButton is clicked, the form is rerendered and the response looks
> like this:
> {noformat}
> <partial-response><changes><update id="someID"><![CDATA[
> ...
> <script src="path_to_some_script?param=asd&important=param"></script>
> ]]</ ... >
> {noformat}
> But this is wrong. Because script tag is already in CDATA, so there is no
> need for XML encoding for '&' entity.
> This further causes script loading to fail (performed by jsf.js), whenever
> parameters are needed (e.g. portal environment),
> because script is downloaded from
> {noformat}"path_to_some_script?param=asd&important=param" {noformat}
> instead of
> {noformat}"path_to_some_script?param=asd&important=param"{noformat}.
> Another very similar issue is when CDATA element is present in a re-rendered
> fragment. Example:
> {noformat}
> <h:form>
> <a4j:commandButton render="@form" value="rerender me"/>
> <style type="text/css">
> /* <![CDATA[ */
> .somecssclass {...}
> /* ]] */
> </style>
> </h:form>
> {noformat}
> The AJAX response then looks like so:
> {noformat}
> <partial-response><changes><update id="someID"><![CDATA[
> ...
> <![CDATA[
> ...
> ]]
> ...
> ]]</ ... >
> {noformat}
> And this is incorrect XML, since CDATA cannot contain ']]', so the response
> is discarded.
