If I have a global event that is namespaced such as in the following gist:

https://gist.github.com/1b1c48ed39f679c77fc4

It will never be triggered.

Looking at the code, the $.bind function keeps track of all events used in a global array in this line:

Keep track of which events have been used, for global triggering

jQuery.event.global[ type ] = true;

Firstly it seems like this should be used only for global events, but in any case the type used here is without the namespace.

When triggering the event the following code in the trigger function will not work:

Only trigger if we've ever bound an event for it

if ( jQuery.event.global[ type ] ) {

jQuery.each( jQuery.cache, function() {

if ( this.events && this.events[type]) {

jQuery.event.trigger( event, data,

this.handle.elem );

}

});

}

First problem is that in the first line of this code, the type value still contains the namespace and so won't match the way that bind was storing this value in the global array without namespace.

If we simply fix that problem, the event will be fired, but exposes another problem in that the if statement inside the anonymous function passed to the .each() does not check to see if the namespace matches before triggering the event.

This clearly seems like a bug that needs to be fixed.
