Null element error when unselecting multiple select options

[bigredradio]

I am not sure how this is happening, but I found the area that needs to be trapped. When I have a select element with the multiple attribute. When I deselect all options, I get an error "elems is null" at line 648 of 1.4.2 non-minified version.

Here is a possible fix: Go through the array, only saving the items that pass the validator function if (elems == null) return ret;

I need to make updates to the page when no options are selected and the event "change" works properly with this addon. Otherwise I get an error and the change event stops working altogether.

The code wrapped. The only addition is: if (elems == null) return ret;

Please provide a ​reduced test case.

I'm going to close this ticket until a test case is provided. The error is occurring in jQuery.grep(). The call stack from a test case would make it clear how we got there.
