onUserAfterSave joomla event is triggered twice

Hi, I am trying to use onUserAfterSave joomla event:


but when Community Builder is installed, after new user registration, onUserAfterSave event is triggered twice and I get a 'new user created' and right after that - 'existing user updated'. It happens only on user registration.
Is it possible to avoid this double triggering?

That's normal. We have to create the user in order to use their user id in other processes, which may trigger an update. There is no avoiding this. Why is this causing a problem for your plugin? No plugin should be dependent on an event only firing once and if it is it should have at minimum static caching implemented to account for that.

It causes problem because upon user creation I cannot distinguish is it a new user creation or an update on existing user. To be honest I would like to use CB triggers but I don't know how to implement it in a joomla plugin script and I can't find an answer or example how to do it. This  using cb triggers document is too complicated for me to understand. I would love to see a working script... 

If them being a new user is all that matters then check against $isNew and ignore if it's false. It will be true when CB first creates the user. You can also add static caching to the function to ignore subsequent calls to that event for a specific user id if the second call from CB is an issue for you.

As for CB triggers they're meant to be used in CB plugins not Joomla plugins. They can also be used in CB Auto Actions. You could try using CB Auto Actions as you may not need to code a plugin at all depending on what you're trying to do. I can make some recommendations if you provide more details about what you're trying to do.

Auto Actions is a very nice plugin I am using it. Thank you for your reply and suggestions.
