Input text readonly attribute in JSF


JSF rocks!
If you want to use readonly property in h:inputText, using readonly=”true” attribute brings you in confusing, because value of this element is unrestorable after request will performed.

Javascript way works in Firefox only! Skip it, here just for ex.

/**
 * Add readonly attribute to element
 */
function addReadonly(obj){
	$(obj).attr('readonly', 'readonly');
	return false;
}

/**
 * Remove readonly attribute to element
 */
function removeReadonly(obj){
	$(obj).removeAttr('readonly');
	return false;
}

// in element, add attrs
onkeydown="addReadonly(this);" onkeyup="removeReadonly(this);"

And to help us, use next JSF workaround.
Add property to bean:

    /**
     * Need for readonly properties processing
* Allows to restore value of input. */ public boolean isReadonly() { return FacesContext.getCurrentInstance().getRenderResponse(); }

In page add readonly attr:

readonly="#{MyBean.readonly}"
