[Tapestry-developer] Newbie question : Property not found Exception

Hi,

I am new to Tapestry & have written a very simple application which takes input the first page & echoes it on the next page. I am attaching all the files for the application. I think that I am doing some basic thing wrong. Please help.

Thanks,

Aejaz

The error which I get in the Browser is,

Name: com.primix.tapestry.RequestCycleException
Message: Unable to resolve property Name of tutorial.formTest.Home@3bbafc[null].

I am little bit confused about 'name' property in the binding, what is it supposed to refer to ?
