Manuel K created MYFACES-4589:
---------------------------------
Summary: PropertyNotFoundException in nested components if
attribute has same name as bean
Key: MYFACES-4589
URL: https://issues.apache.org/jira/browse/MYFACES-4589
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 4.0.0, 4.0.1
Environment: primefaces-test project, jakarta branch
Reporter: Manuel K
I apologize in advance if this one is a SOB to debug and hopefully fix. Maybe
not though?
Given the following nested component structure:
panel (composite component) -> panel (taglib component) -> departmentInfo
(composite component) -> outputIconText (composite component) -> icon (taglib
component)
The panel composite component and the panel taglib component have an attribute
called "color". The departmentInfo component uses "color" in an EL expression,
which is supposed to be a call to a named bean "Color":
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<ui:component xmlns="http://www.w3.org/1999/xhtml";
xmlns:cc="http://xmlns.jcp.org/jsf/composite";
xmlns:ui="http://xmlns.jcp.org/jsf/facelets";
xmlns:test="http://xmlns.jcp.org/jsf/composite/components";>
<cc:interface>
<cc:attribute name="value"
required="true"
type="org.primefaces.test.Department"/>
</cc:interface>
<cc:implementation>
<div id="#{cc.clientId}">
<test:outputIconText icon="#{icon.test} #{color.blue}"
value="#{cc.attrs.value.name}"/>
</div>
</cc:implementation>
</ui:component> {code}
Somehow it seems to be interpreted as the attribute though, because the
following exception occurs:
{code:java}
Caused by: jakarta.el.PropertyNotFoundException: Property [blue] not found on
type [java.lang.String]
at jakarta.el.BeanELResolver$BeanProperties.get (BeanELResolver.java:251)
{code}
The exception occurs only using MyFaces ({_}mvn clean jetty:run -Pmyfaces40{_})
but works using Mojarra ({_}mvn clean jetty:run -Pmojarra40{_}). You can find
my reproducer here:

Thank you very much in advance!
