Re: escape attribute inside the selectItem component is not evaluated

[[EMAIL PROTECTED]]

Hi Simon,

i've created a jira issue --> MYFACES-1897, but i don't found the 
"licensed under the ASF" checkbox to tick them. Maybe you can do it for 
me, if you want or can or ... ;)

bb, Jörg

Hi ,
i tried to run this code:

<t:buffer into="#{myBuffer}">
    <h:outputText value="#{something}"/>
    <h:outputText value="#{somethingWithUnderline}"
                      style="text-decoration:underline"/>
    <h:outputText value="#{somethingelse}"/>
</t:buffer>

<h:selectOneRadio ... >
    <f:selectItem itemValue="1" itemLabel="#{myBuffer}" escape="false">
</h:selectOneRadio>

but my buffercontent is escaped by the selectOnRadio renderer. I take 
a look inside the selectItem component and i see there is a member 
named escape.
Weird.

There is no escape property documented for SelectItem here:
 http://java.sun.com/javaee/javaserverfaces/1.1/docs/api/index.html

And there is no escape property documented for SelectItem here:
 http://java.sun.com/javaee/javaserverfaces/1.2/docs/api/index.html

But there is one here:
 http://java.sun.com/javaee/5/docs/api/

There is none implemented for myfaces core 1.1.x, but it is implemented 
in core 1.2.x

Dennis Byrne added this attribute in r415043 with the message "added ... 
for binary compatibility with the RI". So it would appear to be a case 
where Sun's implementation was not compliant with the specification (how 
the hell did it ever pass the TCK with an extra method in the API?!), 
and myfaces was then tweaked to add the extra method. Given that 
history, it's no big surprise if the renderers were not updated to match.

And (no surprise) it appears that the jee5 docs are being generated from 
Sun's codebase, and therefore are picking up Sun's incompatibilities and 
declaring them as "the spec". Sigh.

But the HtmlRadioRendererBase.renderGroupOrItemRadio() method does not 
fetch the escape value of the selectItem and the
HtmlRenderUtils.renderLabel method has not a parameter for the escape 
attribute.

Same problem is by using the <t:selectOneRadio ... > component.

To fix the problem i've done this:

HtmlRadioRendererBase.renderGroupOrItemRadio() Line ~199 :

// label element after the input
boolean componentDisabled = isDisabled(facesContext, selectOne);
boolean disabled = (componentDisabled || itemDisabled);
boolean escape = selectItem.isEscape();

HtmlRendererUtils.renderLabel(writer, selectOne, itemId,
                selectItem.getLabel(), disabled,escape);

HtmlRendererUtils.renderLabel() Line ~1352:

public static void renderLabel(ResponseWriter writer, UIComponent    
    component, String forClientId,String labelValue, boolean    
                disabled) throws IOException {
renderLabel(writer, component, forClientId, labelValue, disabled, true);
}


/**
 * Renders a label HTML element
 */
public static void renderLabel(ResponseWriter writer, UIComponent
            component, String forClientId,String labelValue,         
boolean disabled, boolean escape) throws IOException {

...

if ((labelValue != null) && (labelValue.length() > 0)) {
    writer.write(HTML.NBSP_ENTITY);
    if (escape) {
        writer.writeText(labelValue, null);
    } else {
        writer.write(labelValue);
    }
}
...

maybe it helps someone.

I guess that for compatibility with the RI we should implement this too.

Could you please create a JIRA issue for this? If you are happy for your 
patch to be included in myfaces, please remember to tick the "licensed 
under the ASF" checkbox..

Thanks,
Simon
