luca stancapiano updated SEAMFACES-183:
---------------------------------------
Description:
If I use a value expression in a composite component, it is rejected and moved
to a default value. Here an example of a jsp:
{code}
<ui:composition ................
xmlns:p="http://java.sun.com/jsf/composite/components/property";
.........
<p:input id="number" label="#{bundles.messages.receipt_number}">
............
</p:input>
<h:button id="cancel" value="#{bundles.messages.template_linkReset}"
outcome="/receipt.xhtml"/>
...........
{code}
The input composite component property:
{quote}
<ui:composition .............
xmlns:cc="http://java.sun.com/jsf/composite";>
<cc:interface componentType="org.jboss.seam.faces.InputContainer">
<cc:attribute name="label" required="true"/>
................
</cc:interface>
<cc:implementation>
..............
<h:outputLabel id="label" for="" value="#{cc.attrs.label}:"
styleClass="">
</h:outputLabel>
..............
{quote}
The problem is inside the encodeBegin method of
org.jboss.seam.faces.component.UIInputContainer class:
{quote}
...............
if (!getAttributes().containsKey(getRequiredAttributeName()) &&
elements.hasRequiredInput()) {
getAttributes().put(getRequiredAttributeName(), true);
}
if (!getAttributes().containsKey(getLabelAttributeName())) {
getAttributes().put(getLabelAttributeName(),
generateLabel(elements, context));
}
...............
{quote}
The containsKey method of the
javax.faces.component.UIComponentBase$AttribuetsMap class ignores all keys from
a subclass of the UIComponentBase, in our case the UIInputContainer. Doing an:
{quote}
getAttributes().get(getLabelAttributeName())
{quote}
we get the correct result. This achievement is showed in the JSF javadocs
(http://javaserverfaces.java.net/nonav/docs/2.1/javadocs/javax/faces/component/UIComponentBase.html):
??citation??
If the attribute name specified as a key matches a property of this
UIComponent's implementation class, the following methods will have special
behavior:
containsKey - Return false.
get() - If the property is readable, call the getter method and
return the returned value (wrapping primitive values in their
corresponding wrapper classes); otherwise throw IllegalArgumentException.
put() - If the property is writeable, call the setter method to set
the corresponding value (unwrapping primitive values in their corresponding
wrapper classes). If the property is not writeable, or an attempt is made to
set a property of primitive type to null, throw IllegalArgumentException.
remove - Throw IllegalArgumentException.
