[Webtest] Re: NullPointer Exception at clicklink

Ok, I changed it to set window.location instead of calling the=
window.navigate function. The test now passes. I further updated=
Page1.html to use a form and call form.submit with method=3D"POST" and=
action=3D"Page2.html" and tried running the webtest again. It fails this=
time with a ClassCast Exception. I opened the page myself in IE and=
Mozilla and it works in both when I click the link. Any Ideas?
Regards,
John
P.S. The new source for Page1.html is below:
Page1.html
--------------------------------------------------------------------------
<HTML>
<HEAD>
<TITLE>TEST PAGE 1</TITLE>
</HEAD>
<BODY>
<FORM method=3D"POST" name=3D"Form1" action=3D"Page2.html">
</FORM>
<A HREF=3D"javascript:gotonextpage()">PAGE2</A>
=0D
<SCRIPT LANGUAGE=3DJavaScript>
function gotonextpage()
{
document.forms[0].submit();
}
</SCRIPT>
</BODY>
</HTML>

My Mozilla says:
Error: window.navigate is not a function
It seems to be an IE specific function. This would explain why your webtest=
doesn't run as expected.

of the form fields are submitted. I have a clickbutton test that submits=
the form and another that uses a clicklink to submit the form. When=
