hi. i have the same error.

maybe it's possible change HashMap to ConcurentHashMap ?
private final Map<WaveType, WaveSubscription> notifierMap = new HashMap<>();

java.util.ConcurrentModificationException

Which version are you using ? I think that the fix I made for 7.7.4 is not enough.
I have pushed a lot of changes for 8.0.0 and I have to backport some of them to create another rebound (7.7.5).

Changing the map type is not really a good thing because all calls of unlistenAll are done into the same thread (JRebirth Internal Thred : JIT => serialization).

But it implies to be able to avoid to release some WaveType notified to keep some the feature alive.
So I have added a new annotation @Releasable to let the component listening the WaveType even it was removed from its parent.

the version is 7.7.4

may be ThreadLocal will be good?

for me previous version 7.7.2 was fine, but i found that you released new version and tried to use it

Let's go to publish the 7.7.5 !

It's already fixed into 8.0.0-SNAPSHOT, I will perform the backport and the release today

A sample has been pushed on latest MasteringTables development branch (GameMenuModel will not be released when it is removed from its parent to keep its feature alive)

Thank You!
I really like you JRebirth!
And when will be possible to use 8 version (from maven)?

Thanks, there is still 2 small features to be done, and I will publish the first 8.0.0 stable version with a lot of new features and unfortunately some API change...

But you can grab the snapshot version here :http://oss.jfrog.org/simple/oss-snapshot-local/org/jrebirth/af/core/8.0.0-SNAPSHOT/ (not yet build, I will powered on our ci server to perform some build)

You will be informed when all release will be available, stay tuned !

7.7.5-SNAPSHOT is ready to be tested (available on OJO) let me know if it works for your application.

https://oss.jfrog.org/repo/org/jrebirth/af/core/7.7.5-SNAPSHOT/

The mastering table demo was fixed by this version and upgraded to 1.5.0, runnable here : http://sites.jrebirth.org/org.jrebirth-7.7.5-SNAPSHOT/apps/MasteringTables.html

Thanks, today i will test it, and write here =)

I have attached this library ( core-7.7.5-20141012.205140-5.jar ) to my project instead of 7.7.2
at the first look works well, as 7.7.2
thank You again =)
waiting for 8 version

All builds are running I will publish 7.7.5 on maven central tomorrow, thanks for your help (feedback, test and patience)
