[jboss-jira] [JBoss JIRA] Closed: (JBPM-767) ExpressionEvaluatorHandler has BeanInfo, which does not use the correct set of methods

ExpressionEvaluatorHandler has BeanInfo, which does not use the correct set of methods -------------------------------------------------------------------------------------- Key: JBPM-767 URL: http://jira.jboss.com/jira/browse/JBPM-767 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.1.4 Reporter: Kannan Ekanath Assigned To: Tom Baeyens Fix For: jBPM 3.2 alpha 2 ExpressionEvaluatorHandler doesnt work in the expected way for subclasses. To quote an example consider, public void testSome() { JbpmExpressionEvaluator e = new JbpmExpressionEvaluator(); final Book book = new Book(); book.setUseful(false); VariableResolver variableResolver = new VariableResolver() { public Object resolveVariable(String pName) throws ELException { return book; } }; e.setVariableResolver(variableResolver); System.out.println(e.evaluate("#{book.isUseful}", new ExecutionContext(new Token()))); } Carefully note that useful is an attribute, isUseful is the bean getter. The above code works fine. However, if you have any subclass of a book, say for example, replace the line, final Book book = new Book(); final Book book = new MySubclassOfBook(); Now the same code gives the error, Caused by: org.jbpm.jpdl.el.ELException: Unable to find a value for "isUseful" in object of class "MySubclassOfBook" using operator "." This is because, in bean introspection BeanInfoManager.java --> method initialize(Logger logger) void initialize(Logger pLogger) throws ELException { ... Method[] methods = mBeanClass.getDeclaredMethods(); for (int i=0; i<methods.length; i++) { Method method = methods[i]; } It is using the *getDeclaredMethods()* API and not *getMethods()*. The getdeclaredmethods api gives apis declared only by that class and not inherited ones.
