> Key: TOMEE-1205
> URL: https://issues.apache.org/jira/browse/TOMEE-1205
> Project: TomEE
> Issue Type: Bug
> Affects Versions: 1.7.0, 1.6.0.1, 1.6.0.2
> Environment: Windows 7 64 Bit
> java version "1.7.0_21"
> Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
> Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
> 1.6.0.1 webprofile
> 1.6.0.2 webprofile
> Reporter: Patrick Pekczynski
> Assignee: Romain Manni-Bucau
> Priority: Blocker
> Fix For: 1.7.0
>
> Attachments: JAVAEE-API-EL.patch, TOMEE-EL.patch, animaltest.war,
> animaltest.zip

> Since version 1.6.0.1 (including 1.6.0.2) (both webprofiles) in EL-expression
> on XHTML-pages one can no longer provide a 'subclass' as argument to a method
> with a method that takes a superclass as argument.
> In 1.6.0 webprofile this worked without problems
> Consider
> a class
> @Named
> @RequestScoped
> public class Zoo {
> private List<Animal> animals;
> public Zoo() {
> this.animals = new ArrayList<>();
> this.animals.add(new Bird());
> this.animals.add(new Mammal());
> }
> public List<Animal> getAnimals() {
> return this.animals;
> }
> public String getName(Animal animal) {
> return animal.getName();
> }
> }
> and a hierarchy
> Bird extends Animal
> Mammal extends Animal
> when iterating over the list of animals [Bird, Mamal] on an XHTML page
> calling zoo.getName(Bird) leads to an error stating
> SEVERE: Servlet.service() for servlet [FacesServlet] in context with path
> [/animaltest] threw exception [java.lang.NoSuchMethodException:
> org.animal.Zoo$$OwbNormalScopeProxy0.getName(org.animal.Bird)] with root cause
> java.lang.NoSuchMethodException:
> org.animal.Zoo$$OwbNormalScopeProxy0.getName(org.animal.Bird)
> at java.lang.Class.getMethod(Class.java:1624)
> at javax.el.BeanELResolver.invoke(BeanELResolver.java:394)
> at javax.el.CompositeELResolver.invoke(CompositeELResolver.java:225)
> at org.apache.el.parser.AstValue.getValue(AstValue.java:173)
> at
> org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:184)
> at
> org.apache.webbeans.el22.WrappedValueExpression.getValue(WrappedValueExpression.java:70)
> at
> org.apache.myfaces.view.facelets.el.ELText$ELTextVariable.writeText(ELText.java:219)
> However the EL expression should be aware of the method Zoo.getName(Animal)
> that perfectly allows any subclass of Animal as an argument.
> As this was working in 1.6.0 webprofile without problems I wonder what has
> changes if "only" security updates have been applied...
> Would be great if you can have a look at this.
> Thanks and best regards,
> Patrick
