Problem with fadeIn/fadeOut in Jquery >= 1.4

Problem with fadeIn/fadeOut in Jquery >= 1.4

Hello,

With Jquery >= 1.4 I have a problem with the effect fadeIn/fadeOut,the firefox console shows it:
Error: d is undefined
Archivo de origen:  includes/jquery-1.4.2.min.js
Línea: 41


Line of error:
  1. w)return c.queue(this[0],a);return this.each(function(){var d=c.queue(this,a,b);a==="fx"&&d[0]!=="inprogress"&&c.dequeue(this,a)})},dequeue:function(a){return this.each(function(){c.dequeue(this,a)})},delay:function(a,b){a=c.fx?c.fx.speeds[a]||a:a;b=b||"fx";return this.queue(b,function(){var d=this;setTimeout(function(){c.dequeue(d,b)},a)})},clearQueue:function(a){return this.queue(a||"fx",[])}});var Aa=/[\n\t]/g,ca=/\s+/,Za=/\r/g,$a=/href|src|style/,ab=/(button|input)/i,bb=/(button|input|object|select|textarea)/i,
I am trying to show a object:

  1. $(document).ready(function(){ $('#notis object').fadeIn(1500); };
Here the XHTML:
  1. <object type="text/html" data="<?=_BLOG_?>"></object>
With Jquery version < 1.4 I haven't got problems but I need Jquery >= 1.4 because I use the delay function to animate.

Thanks for your help
