[jQuery] Problems to migrate from 1.1.2 to 1.1.4

[jQuery] Problems to migrate from 1.1.2 to 1.1.4


I am trying to migrate my web app from jQuery 1.1.2 to 1.1.4.
Just to begining I got some error when I load some pluguins. All
errors are related with $...
I used:
script src="/InmoFusion2/libs_Ext/jquery/jquery.js"></script>
<script>
    jQuery.noConflict();
</script>
And then :
<script src="/InmoFusion2/libs_Ext/jquery/deserialize.js"></script>
When I try to execute the same code with 1.1.4 I get some errors: By
example loading jQeury-calendar.js
Runtime error: $.fn is null or not an object...
-----
$.fn.calendar = function(a) {
    // attach the calendar to each nominated input element
    this.each(function() {
        if (this.nodeName.toLowerCase() == 'input') {
            popUpCal.connectCalendar(this);
        }
    });
    return this;
};
-----
Are there any new way to call noConflict method?
Thanks!!!
