Little help with EL: concat static string and databound number

Question

Hi OTN,
I'm a bit stuck with a simple - as I thought - case: concatenating static string and databound number in EL:
I have a deffered expression like:
#{1 != 2 ? ('Number is ' bindings.SomeNumber.inputValue) : 'no number'}
1 and 2 are databound values too but the question is about showing "Number is 5" where 5 is a SomeNumber.
Expression editor shows error on 'Number is'. And the error dissapperars if I remove "bindings.SomeNumber.inputValue".
How can I concatenate them?
Thanks.

Another option for you is to write that formatting logic in a static utility classes that takes parameters to return strings.
Ex.:
*/WEB-INF/utils.tld:*
<taglib xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd" version="2.1" xmlns="http://java.sun.com/xml/ns/javaee">
  <description>utils</description>
  <display-name>utils</display-name>
  <tlib-version>1.0</tlib-version>
  <short-name>utils</short-name>
  <uri>http://biz.com/utils</uri>
  <function>
     <name>getFormattedNumber</name>
     <function-class>com.mybiz.FormatUtils</function-class>
     <function-signature>java.lang.String getFormattedNumber(oracle.jbo.domain.Number)</function-signature>
  </function>
</taglib>And then you use them in your EL expression like this:
page.jspx:_
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:f="http://java.sun.com/jsf/core"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
          xmlns:utils="http://biz.com/utils">
  <af:outputText value="#{utils:getFormattedNumber(bindings.Number.inputValue)}"/>
</jsp:root>Better to have many options isn't it?
