Access violation in juce_ListenerList.h

I have found problem with my GUI and I don’t know if I am missing something. I am using JUCE 4.2.3. Inside my PluginEditor I have component “Foo”

class Foo : public Component, public ChangeListener

Inside constructor I am adding ChangeListener


Later I am calling


Even if changeListenerCallback function is empty I am getting Access violation. How can I solve this problem?

have you tried to using a member version of the animator? Sounds like the connection is getting broken and then the animator is trying to send a message to a nullptr. Perhaps the host is breaking the connection and you’d be better off using your own as opposed to the global

I don’t know if it is possible. It looks that connection is fine because changeListenerCallback is recalling properly, whole code inside is working fine. It is crashing on callback return.

Can you post a stack trace?
