jsf 1.1 and jsf 2.0

[nimo22]

In jsf 1.1,

I can use something like:

<h:outputText value="size: #{_e.listHobby.size}" />

where the (collections-build-in-method) "size" returns the size of the java.util.list "listHobby".

In JSF 1.1, this works!

In JSF 2.0, this does no more work!

It returns this error:

java.lang.NumberFormatException: For input string: "size"
     java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
     java.lang.Integer.parseInt(Integer.java:449)
     java.lang.Integer.parseInt(Integer.java:499)
     javax.el.ListELResolver.toInteger(ListELResolver.java:407)
     javax.el.ListELResolver.getValue(ListELResolver.java:199)
     javax.el.CompositeELResolver.getValue(CompositeELResolver.java:175)
     com.sun.faces.el.FacesCompositeELResolver.getValue(FacesCompositeELResolver.java:72)
     org.apache.el.parser.AstValue.getValue(AstValue.java:134)

Why is that so?

Nimo,

Collection does not have getSize() method, so JSF's resolver fails. From JSF 1.1 to 2.0 EL handling has evolved, so it's not working anymore. Use JSTL 'length' function.
