Issues with jQuery UI 1.8.2 and Dialog Options not executing 'open' when 'show' also specified

Issues with jQuery UI 1.8.2 and Dialog Options not executing 'open' when 'show' also specified

I am passing-in some dialog options to my dialog
 
                    var dialogOpts = {
                        "autoOpen" : false,
                        "draggable" : true,
                        "modal" : true,
                        "resizable" : false,
                        "title" : "Change Password",
                        open : function() {
                            if($(changePasswordForm.oldpassword).css("display") == "none") {
                                $(changePasswordForm.newpassword).focus();
                            }
                            else {
                                $(changePasswordForm.oldpassword).focus();
                            }
                        }
                    }













 
If I also specify a "show" : "slide" in the options, the 'open' function will not execute.  Is there a specific way that we are to fire the 'open' function() when an anmiation effect is also specified?
