Maybe you want to have a look at the PrimeFaces – showcase.
http://primefaces.org/showcase
eg http://primefaces.org/showcase/ui/panel/card.xhtml for CSS-integration
or eg http://primefaces.org/showcase/ui/misc/context.xhtml for JS-integration
Some basic ideas also apply for JSF without a component library like PrimeFaces. Or you like to use PrimeFaces to create rich user interfaces.

Betreff: Re: [faces-dev] Full Technology Set
You have confirmed for me,
with JSF, on occasion I may need CSS + HTML + EL.
It would save me alot of time if you could confirm for me whether there may be an occasion I would also NEED
to integrate _javascript_ with JSF or on the contrary
JSF + CSS + HTML+ EL is the full set and complete set for the Browser as the Graphic User Interface ?

try to ask the EL guys, Faces just reuses the ExpressionLanguage

Thanks.
Using the error message
java.lang.NumberFormatException: For input string: "Go "I made some more guesses I experimented with this
value="#{'50' + 70}"
the answer is 120 as the button label.
Something doesn't seem quite right to me.
Any insight into this would be good too ?

I have a book I am using to practice Java Server Faces.
In this book the example code given is
<h:commandButton
value="#{'Go ' + xyz.submit}"
action="">
Using the above syntax I was getting the error
java.lang.NumberFormatException: For input string: "Go "
After some intuitive guesses I changed the syntax to this.
value="Go #{xyz.submit}"
This produced the expected results, so I now know how to dynamically update button label.
My question is , did the book provide me with incorrect syntax or
was there a change in the specification ?
