convert string to Integer in JSF code only

can i use following

sortBy="#{Integer.parseInt(custprofile.storeNo)}"

It's giving me error. But how do i resolve it. I need to do conversion at display time only and NOT in java code

The problem with this code is that the EL needs to reference an instance of a Java Bean and it looks like you're referencing the static class Integer.

Why do you need to avoid putting the solution in the Java code?

I would suggest using Javascript as if you want a pure client side solution.
The code example you gave will send a request to the server.

It's unnecessary. EL is automatically going to convert, since the web page isn't binary, it's text. So all that's required is:

Actually, in this case, a property binding is being set up, but EL handles that automatically as well. So no explicit conversion needed.

Oh wait a minute. Is this what you're trying to address? http://www.coderanch.com/t/534046/JSF/java/sortby

What you actually need is a Comparable interface on the Model object in the backing bean. Or you could front the current model with a façade model whose storeNo field is an integer instead of String.

I have changed below statement, which was giving parsing error while page rendering

sortBy="#{Integer.parseInt(custprofile.storeNo)}"

TO below statement

sortBy="#Integer.parseInt{custprofile.storeNo}" which didn't give me error

But before i can test if it sorts or it really works, i am stuck with other issues with web services security. If above one works i will update

i should have read your comments clearly before replying. Anyway, it's not working

And now coming to the point. Changing the value to Integer is lot of work on the java code.

I think, we can't convert string to integer in the JSF for the SortyBy attribute

let me think

As Tim Holloway said, the EL will convert the value into a String for you without having to do so in the backing bean's Java code. All you need to do is make sure there's a public int getStoreNo() method in your class.

yeah, i just changed the type from String to Integer. It was not actually that much of code change

it's one of the field of web service request. on web service it has defined it as String, so i have also had it as String

now i changed it to Integer and doing parsing while i get the results back from web service response
