[Webtest] Dynamically generated form

[Ali, Haneef]

Hi,

My page dynamically generates forms  using Ajax.  Webtest is not able to find 
out the dynamically generated form.  I can see the dynamically generated form 
in the generated source view of the browser.  Does webtest supports dynamically 
generated form?

Thanks,
Haneef

Subject: [Webtest] Null Pointer Exception in test script by webtest

Hi,

I am getting a strange issue in one of my test script. I executed a script and 
all of the steps passed but at the last step it failed by giving the following 
error.

I am not able to resolve this Null Pointer exception error. I would appreciate 
if any one can help me out of this issue.
