Windchill 10.1 Info Engine webjects Behavior

Hi All,

            We are in the process of migrating Windchill 9 customization to Windchill 10.1 . Behavior of Info engine webjects has been changed in Windchill 10.1 .Is there any link or materials which talks about the webject changes in Windhill 10.1.

Example:

     In Windchill 9,Query objects complied successfully without type and where tag but,in Windchill 10.1  getting compilation error saying the "TYPE" and "WHERE" parameters must be provided.
