I have been getting a few errors when trying to use the asp.net ajax framework.
The one error message is:
Error: Sys.ArgumentTypeException: Object of type ‘Sys_Application’ cannot be converted to type ‘Sys._Application’/
Parameter name: instance
This is caused by having SmartNavigation turned on for the page.
The other error I was getting was this Sys.ArgumentOutOfRangeException. Value must be an integer. Parameter name: X. Actual value was NaN.
This error is caused by using a “yes” or “no” for “frameborder” for a frame.
Yes and No are valid entries but the framework is expecting a “1” or a “0”.
