Lutz Ulrich commented on RF-11144:
----------------------------------

I'm using PrimeFaces along with RichFaces, too, and have the same problem.

In order to avoid such conflicts, RichFaces' jquery.js (and all jquery.js files of other JSF libraries) should contain a test which checks if jquery has already been initialized. 
That is, check for example, if the variables window.$ or window.jquery are already defined.

A workaround is to 'override' RichFaces' version of jquery.js.

RichFaces jquery.js is integrated into the HTML document via:

<script type="text/javascript" src="/oswebjsf2/javax.faces.resource/jquery.js.faces"></script>

It is loaded from richfaces-core-impl-<version>.jar/META-INF/resources/jquery.js .

If the web app's folder resources/ contains a file with the same name, that resource file will be loaded instead of the one in richfaces-core-impl-<version>.jar, because files in the web app's resources folder have a higher priority than files in JARs.

One can copy RichFaces jquery.js from richfaces-core-impl-<version>.jar into the web app's resources/ folder. In that copy, one can add additional code which checks if jquery has already been initialized:

(function( window, undefined ) {

// THE TEST:
if (!window.$) {

// ...

window.jQuery = window.$ = jQuery;
} // end test if window.$ 
})(window);

> This feature would be awesome cause it could easy integration with others components suites like primefaces.
> if we could say to richfaces where it could  find its jquery reference, we could config it to use jquery from primefaces for example.
> <h:outputScript library="primefaces" name="jquery/jquery.js" />
> avoiding jquery double loading and conflicts between libs.
