    h:outputFormat and f:param with complex value

      Hello,

       

      I would like format a message with 2 parameters. One of the parameters cannot be given to f:param directly in the value attribute since I need to format it also. See example below :

       

      JSF :

       

      <h:outputFormat value="#{messages['my.message']}">
     <f:param value="#{myBean.stringValue]}" />
     <f:param>
          <h:outputText value="#{myBean.aNumericValue}">
               <f:convertNumber maxFractionDigits="0" />
          </h:outputText>
     </f:param>
</h:outputFormat

       

      messages.properties :

      my.message=A test message {0} {1}

       

      How can I do this ?

       

      Thanks for your help.

          hi  tried to solve this problem,

           

          approach 1

          -----------------

           

          aNumericValueFormatted is a new getter method which will return the formatted value.

           

          <h:outputFormat value="#{messages['my.message']}">
     <f:param value="#{myBean.stringValue]}" />
     <f:param value="#{myBean.aNumericValueFormatted}">
     </f:param>
</h:outputFormat>

           

           

           

          approach 2(This has some issue)

          ----------------

          can you try the following snippet

           

                  

          <h:outputText value="1234.123466666666666" binding="#{requestScope.simple}" rendered="false">
            <f:convertNumber maxFractionDigits="6" ></f:convertNumber>
        </h:outputText>
        <h:outputFormat value="A test message {0} {1}">
            <f:param value="Simple zero"></f:param>
            <f:param value="#{requestScope.simple.value}">
            </f:param>
        </h:outputFormat>

            Thank you for your suggestions.

            Of course, approach 1 works but I don't like it since I have to modify my model and introduce presentation concerns in Java code.

            Approach 2 doesn't work : the value stores in the binding property is of type "javax.faces.component.html.HtmlOutputText".

             

            Finally, I added a new method in a bean :

             

            public String formatNumber(double number, String format) {

                    final DecimalFormat decimalFormat = new DecimalFormat(format);

                    return decimalFormat.format(number);

                }
