Re: Where does log4j output go?

Hi,
Read the log4j docs. Use a console apender.

Re: list serialization

[mirceade]

I'm using list of serializables just fine (it only shows some warnings
since gwt 1.6) because my domain classes are not ready to inherit some
strange superclass just for gwt ser. to work. So I guess you're using
1.5 or lower.

Re: RPC Serialization of abstract classes

[mirceade]

Well, I have finally found the problem:
Drums roll:
The GWT Timer class is not serializable (my super class had a Timer
field buried down in there)! The compiler doesn't complain at all and
when the time to serialize comes it just doesn't serialize the whole
class without throwing any exception. Thanks Paul for your support and
I'm sorry for wasting your time with this.

Re: GWT: HostedModeException: Expected primitive type int; actual value was undefined

[mirceade]

Hi Igor. I think your problem is related to mine:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3652
But I can reproduce it in both hosted mode and in the browser. I think
there is a serialization issue with the GWT RPC when sending inherited
(super-class) fields.

Re: RPC Serialization of abstract classes

Come on guys, hasn't anybody else used more than plain strings and
ints with GWT RPC? Is this really a bug (not serializing correctly up
on the inheritance chain) or am I doing it all wrong? Help!

Re: RPC Serialization of abstract classes

[mirceade]

I don't either, so it must be a serialization issue with gwt RPC. It
would be very helpful if somebody else would try to reproduce this bug
too.

[mirceade]

Am I doing something wrong? Is this supposed not to happen by design
and I'm forgetting some configuration?

Re: RPC Serialization of abstract classes

[mirceade]

Hi Jim,
Forgot to add:

All classes are defined in the client package and implement
Serializable (yes I know that only the base classes actually have to,
but for the sake of it they all do).
That was just an example to understand the inheritance.

Re: maximize the hosted window...?

[mirceade]

Javascript doesn't usually allow you to maximize the window where your
application is loading, only newly created windows.

RPC Serialization of abstract classes

[mirceade]

Hi,
I've got a problem for which I've filled a bug but I thought I should
have started with the forum first:

I've got an abstract class with an abstract field. I send an object
whose class is derived from this abstract class with the abstract
property set to another object. When sending the parent object through
RPC it's field becomes null with no serialization exception:

public abstract class AbProperty {
}

public abstract class AbClass {
 AbProperty abProperty;
}

public class RealProperty extends AbProperty {
}

public class RealClass extends AbClass {
}


AbClass rc= new RealClass();
rc.setAbProperty(new RealProperty());

---> rpc
on the client an AbClass result is expected but debugging reveals that
rc.abProperty is null!!!

Help is very, very, very much appreciated.
Thanks.
