Re: [faces-dev] Full Technology Set

[<Christoph.Strasser@xxxxxxxxx>]

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.

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 think that never worked, not sure: https://stackoverflow.com/questions/3640254/string-concatenation-in-el

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 ?
