ReferenceError: "validateForm" is not defined. error when executing a clickbutton event.

Hi,

I am getting a very strange Javascript issue while executing one of my test.

This error appears on clickButton event.
*Error:-*
JavaScript error loading page
http://10.208.7.175:8080/IDMProv/getAFResourceList.do?apwaLeftNavItem=JSP_MENU_RESOURCE_REQUEST_CLASSIC&apwaActionScope=user&apwaNewSearch=true:
ReferenceError: "validateForm" is not defined.

)

I checked the html page and the javscript function "validateForm" is defined
in the page itself.

When I manually opens the page in browser it opens without any error. I
tried this test with the latest webtest build.

Would appreciate if any one could suggest me a way to resolve the issue.

Thanks & Regards,
Hitesh
