Hi Giovanni, The only issue I'm aware of is tracked in https://issues.apache.org/jira/browse/BEEHIVE-1060 where a package protected control in a parent page flow is not being initialized when using a derived page flow inheriting from the parent. In this case it throws an NPE when the base class method tries to access the control because the control was never initialized. The non-initialization is similar to your experience but I think different. Your stack trace indicates a problem in the initializeClient() method of org.apache.beehive.controls.api.bean.Controls. The call to the ClassLoader loadClass() is throwing a ClassNotFoundException for the class file of your generated ClientInitializer, operazione1.Operazione1ControllerClientInitializer. You mentioned that you noticed that the ClientInitializer is built. Is the class file in build/WEB-INF/classes/? Is it just an issue with the deployment in your Tomcat 5.5.9 configuration. If you have a simple repro case, you can log a separate JIRA issue.

Hi all, i'm new to the list. I'm trying to build a pageflows hierarchy (pageflow PF1 defines java control C1 and an action A1 that internally performs a call to a method of C1, pageflow PF2 inherits directly from PF1 and performs a forward to A1 ). All is done through annotations, no custom instanciation. I'm developing with BEA 9.2 tools, but I'm using a tomcat 5.5.9 server for project requirements. The application starts fine on PF2, invokes action A1 of PF1 with no problem, but when the java control C1 is first used, i see with the debug tool it is not instanciated (null) . Also, during initialization of pageflow P2, i see in console output the exception reported. It seems like no client initializer class is found for P2, but i'm wondering if it's ordinary stuff, since i see the client initializer class is built for pageflow P1, that in effect is the owner of the java control...Bug??? Apart from this, i would like to know if someone else has already developed something similar and can produce a sample code. Reading beehive 1.0.1 documentation, it seems this kind of inheritance should be fully supported. Problems with the container? Any points? Thanks in advance to who will answer.
