Welcome to the JavaRanch, Muhammad!

RichFaces has quite a few extensions to make displays more sortable using just JSF. RichFaces itself uses jQuery internally in some cases. You might want to check the list of tags and see if any of them help. I use sortable extendedDataTables all the time.

However, sometimes raw jQuery is what you need. You can usually get things to work right by enclosing the <script> elements inside <f:verbatim> elements. Like so:


The rather odd construction here has its reasons.

1. Following the <script> element, we start a JavaScript comment. That keeps the javaScript interpreter from attempting to interpret the "CDATA" as a JavaScript command.

2. The "CDATA" is the XML escape for all text down to its closing "]]>" sequence. Which is also hidden in a JavaScript comment.

The reason for using "CDATA" is that if you're using XHTML, the entire View definition must be valid XML. And while "&", "<" and ">" are all perfectly good JavaScript operators - and likewise the single and double quotes, all of the above have special meanings to XML and therefore must be escaped or the XML may not parse properly. If you didn't use CDATA, you'd have to deal with horrors like this:




Which could have been even worse, but in this particular case, the quotes were all unambiguous. Otherwise you'd have to do stuff like "&quot;are you sure?&quot;". In fact, even the ampersands are OK here, but if there'd been a "if ( a > b )", that would have been certain trouble.
