I've found a strange bug with jQuery tabs. Let's say you add a new Ajax tab, let's call it tab-1. When you click on it, a request is sent to the server.
Add another Ajax tab, let's call it tab-2. When you click on it, a request is sent to the server. When you click on tab-1, the request to the server is sent *twice* Add a third Ajax tab, tab-3. Now clicking on - tab-3 sends *one* request - tab-2 sends *two* requests - tab-3 sends *three* requests And so on.
