Hi,
it seems I was not clear enough:
problem was connecting signal to signal (with less arguments)
not to slot. ( Sorry for including that enum :) )
I did some more testing and realized that
ConnectionType.QueuedConnection is needed to reproduce that error.
I also rechecked the beta1 and it's ok. It's only beta2's problem
(speaking of my system :) )
So if I just add another connect to your example, like this:
meta.zooty.connect( meta.reebo, ConnectionType.QueuedConnection );
I get that message and broken connection.
If you change FailedMetaCall superclass to QObject you get my next favourite
issue: "QObject used from outside its own thread" :)
It would be nice if Signal.emit() used queued/event-based method invocation
in autoconnection mode even if not in QObject derrived class. This check is
done anyway in QtJambiInternal.threadCheck, right?
I also got some JVM crashes while using Drag and Drop.
I'm 90% sure I'm doing something wrong, so I'll have to look into it again
(and again), but I've attached the JVM log, just if you'd like to look at
it.
Jakub

Hi, Jakub.
It seems that queued connections are broken when the signal and
receiving method (or signal) have a different number of arguments,
unfortunately. A workaround would be to make the receiving signal have
the same number of arguments as the sender signal.
You can also apply the attached patch to the Qt Jambi source in order to
fix the bug.

QObject is special in that it has thread affinity to make it easier to
structure code in a thread safe way. Regular objects can be used from
any thread, and do not "belong to a thread" like the QObject does.
Hence, the automatic queued connection across threads only exists when
both the sender and receiver object are subclasses of QObject, since
this is the case where there is a distinct sender thread and receiver
thread.

Yes I know,
I just thought that Signal.emit could do (or rather why is not doing? )
something similar
as QtJambiInternal.threadCheck is doing:
if the receiver is QObject and is in different thread (
Thread.currentThread() != receiver.thread() then act as if sender was
QObject, thus use event delivery instead of method call...
