params not working properly in Edge?

Hi all,

My app isn't functioning properly with Edge (REV 5101 by the time I checked). The one I'm using right now that still work is Edge REV 5045.

I notice that a form_remote submit doesn't include all params I specified in the form. Am I doing something wrong with my way of submitting form? As far as I can tell, I am doing standard thing hence it's currently working properly with Edge REV 5045.

I don't know whether the problem lies in ActionPack or Prototype. Does anyone experience the same problem?

Thank you very much, John
