Type is undefined,Sys is undefined

[Hamayun Khan]

Hi

I have an ajax tab container on aspx page. When I try to view the page I get the type is undefined, sys is undefined errors in the left bottom status bar. This does not happens always. Some times the page loads successfully. When the error occurs then I did not see tabcontiner on the page.

I have also used the tabcontainer on other page which loads successfully with no errors.

Any Help in this issue. Thanks in advance
