Re: ---SPAM--- Re: setting default value for input field?

Hi David,

Life could be easy with facelets. For example:

Tag file: myinputText.xhtml 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
        PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:t="http://myfaces.apache.org/tomahawk"
      xmlns:c="http://java.sun.com/jstl/core"
        >
<ui:composition>
<c:if test="#{empty value}">
        <c:set var="value" value="#{default}"/>
</c:if>
        <t:inputText id="#{name}" value="#{value}" required="#{required}">
                <c:if test="#{!empty size}">
                        <f:attribute name="size" value="#{size}"/>
                </c:if>
            <ui:insert/>
        </t:inputText>
</ui:composition>
</html>

So, on your page:

<my:inputText value="#{myBean.fieldValue}" default="Search..." size="50" 
required="false"/>
 
Best regards,
Aleksandr Mazur,

---SPAM--- Re: setting default value for input field?






Thanks but it does not fit the needs
1) the default value should be configurable per page. It's not the only
hidden field. Some have a searchScope that depend on which page the form
sit in. It can't be initialized by 'managed property'

Cmon, there should be something as simple as defaut="..." that exist in
JSF. I can't believe a form couldn't have default values in the JSP...

Thank you Aleksandr, it does fit my need, i didn't know about the
f:attribute, i'll check if it works for the value (your example use the
size :p )

To people saying it's one backing bean per form, i agree up to some
point. In my case i have only 2 forms and could separate in 2 backing
beans. But main problems are
1) i don't have access to backing bean initialization step thru JSf,
it's manager by struts faces
2) on the same form, default value of some fields depend on current user
profile, on some GET parameters and so on, this make it difficult to
manage somewhere else than in form.

Thanks for help anyway.
