The suspicious thing about your solution is that your smart
implementation of equals() is not symmetric.
In case the observable value is visible only within your project, you
could do this:
interface Subscription {
void unsubscribe();
}
class MyObservableValueT implements

A simpler and more universal solution is to also override removeListener:
public void removeListener(ChangeListener? super T listener) {
super.removeListener(decorated(listener));
}
And the equals() method on decorated listeners only compares the
delegates (thus is symmetric).

Hi,
I'm currently trying to build OpenJFX from source on Windows - I've
followed the instructions on the build page and have Visual Studio 2010,
the June 2010 directx sdk, cygwin and its relevant modules installed.
However, when building it fails at the buildJavaFXPackage task (output
below.)

Hi Thomas!
Thanks for your input. Because I want to decorated listeners added by JavaFX
core I can not use the sub/unsub pattern.
Your second proposal is almost what I do right now. In removeListener I consult
a map where the decorated listeners and their undecorated one lives.
Regarding the
If you are talking about a change to the JavaFX API, we are not likely
to accept such a change if it breaks the contract of equals() or
hashcode(). In your own app it may not matter, but it is dangerous to
assume it won't matter to anyone. Martin owns the core libraries and can

The only thing which I ask for is to flip this „if in the *ExpressionHelper
classes:
So, JavaFX does not break anything and it is up to the app developer to take
the risk or not.
if (listener.equals(changeListeners[index])) {
If we flip this to

Do you have VS 2010 Service Pack 1? I've seen this failure on machines
that don't have SP1 installed.

Yep, null throws a NullPointerException in addListener by design (also in
removeListener) - the listener collection is safe.

Hi Mario,
even if your proposal gets accepted, you would still depend on an
implementation detail of JavaFX, which is always good to avoid.
To sum up, my second proposal compared to your current solution:
(+) your equals() stays symmetric;
(+) no need for an extra Map of listeners.
My second
Probably you avoid the map, but it requires to decorate the listener again,
right?
If you think about the tons of observable values and add/removeListener
operations in an tree view when scrolling it might get costly and put pressure
on the GC.
Anyway, I will be more than happy to assist with
Why not i expect the property to be fully initialize so this would be a
breaking change in behavior.

Ah i missed you passing them to the constructor.
Still i don't see this as much an improvement because we still create a vast

Right. For a pair of addListener-removeListener calls, you have 2
decorations instead of 1. I usually think of the costs in asymptotic

Sure, I just wanted to get the baseline for comparison
Hi Kevin,
Many thanks for that - that has solved the problem! Perhaps the wiki
pagehttps://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFXshould
be updated to note that SP1 should be installed as well as vanilla
VS2010? I would do it myself, but don't have the privileges.
Thanks,
Michael
Glad this solved your problem. I added SP1 to the Wiki page.

I've managed to clone and build OpenJFX successfully, and am now in the
