Thank you very much, I do not know why I didn't find this post but this works perfectly I find this to be a quite elegant solution compared to the different things I tried with the message system which didn't even work out in the end.

Hello,

I have a CommandData Plugin which can have preferences. These preferences are implented in a PreferenceData Plugin. How would I notify the CommandData Plugin that the preferences have changed? I can't get the CommandData Instance from inside the PreferenceData, so I assume that I need to use the message system but when using GePluginMessage() from inside the PreferenceData Plugin I do not receive anything in PluginMessage() inside of the CommandData Plugin.

Is there something I am missing or do I need to use another message system? Thank you in advance.
