Re: java.lang.AbstractMethodError loading Index page with T5.4?
Hi. Turns out to be another JS incompatibility. I remove angularjs from my context and the problem goes.

RE: java.lang.AbstractMethodError - 5.1.0.5
Hi Thiago, Thanks for the response - comments below. >Tapestry-IoC create proxies around your service implementations, so, when >you @Inject UserEntityManager, the object your receive is proxy that >implements UserEntityManager, not BaseEntityManager. This means that the >proxy will invoke a method that returns IPersistentObject, not User. This is the nub of the problem - the proxy implements UserEntityManager, which by definition returns a User object for this particular method - not explicitly a IPersistentObject as in your example, though the returned object does implement IPersistentObject. I thought that the StackTrace might indicate that there is an exception in the ioc registry area that is not being caught / reported properly. If the java.lang.AbstractMethodError had a message that contained something indicating an unexpected return type / class cast issue etc. it would have been easier to pin down. >> This is to reduce the need for explicit casting around the application. >This doesn't seem right to me. You shouldn't rely on an specific >implementation of a given interface. If you need, why return an interface >in first place? Agreed - this is just for convenience in a very context relevant area of the system (user CRUD and other ops) - in other areas of the system the IPersistentObject interface is used as a matter of course in place of Users and other domain objects.

java.lang.AbstractMethodError - 5.1.0.5
Hi,
I came across an interesting issue and thought I would post it so that it
might save someone else some time - I'm not sure if this is down to
questionable coding practise on my part causing the relevant classloader to
burp or Tapestry relevant ... the stack trace is at the bottom of the mail.
I have a service bound to an interface in the ioc registry. The interface
extends another interface and duplicates a method name and parameter list
however the return type in the overridden method is a concrete class rather
than an implementing interface, as specified in the super interface ex.:
public interface BaseEntityManager {
public void IPersistentObject getEntity(IPersistentObjectKey key);
}
public interface UserEntityManager extends BaseEntityManager {
public void User getEntity(IPersistentObjectKey key);
}
This is to reduce the need for explicit casting around the application.
Concrete class User implements IPersistentObject and extends
BasePersistentObject. Service UserEntityManagerImpl implements
UserEntityManager and extends BaseEntityManagerImpl - it implements User
getEntity(IPersistentObjectKey key), which just calls the superclass
equivalent and casts the result to a User object. Service
UserEntityManagerImpl is bound to the ioc registry against interface
UserEntityManager. UserEntityManager is injected into a page and when the
getEntity method is called the stack trace below results. If I use a
non-injected version of the same class via the interface (ex.
UserEntityManager uam = new UserEntityManagerImpl();, uam.getEntity(key)), I
get the expected (correct) result. Is this possibly down to a JIT object
creation issue in the IOC Registry, or the duplicate method name causing
some ambiguity problem on the return type (concrete vs. interface)?
I don't need a solution to this, as I just altered my specialised interface
to have different method names - just thought it might help someone else
trying to trace through a lot of dynamically generated code.

Hi all May I know what does this Exception mean? javax.servlet.ServletException: Servlet execution threw an exception root cause java.lang.AbstractMethodError org.apache.tapestry.AbstractPage.firePageDetached(AbstractPage.java:436) I'm developing a e-shopping system. The login/logout function works fine previously. When I continue to develop other function and look back to login, this exception generated, it may related to some of content refresh and cannot get proper value but I have no idea and how to trace the root cause. The strange thing is that when this exception generated and i press "back" button, desirable output display properly. Any hint would be appreciate, thanks. regards wayne Yahoo!
