Hi Varshini,

I think Tim helped you in your previous post and you were able create subtable using <h:datatable>, then why did you want to move to html table?
And in turn when the page renders it generates html code, So you must be able to do same things with <h:datatable>

use <h:dataTable> which will help you to create a table and it binds with the collection<objects>

And what do you want to save. I guess the table would be coming with the prepopulated data.
Do you want to make edit kinda functionality?

<tr> is representing a row of the particular table.. Here if you want to have data inside the row you must enclose it with <td> or <th> if it is your header.
You have <table> inside the <tr> but no <td> or <th>, so it complains
Use contains method of the collection interface to check whether the value is present in old list, while iterating through new list.
Here, If you have User defined objects in collection then you need to override equals method of the object.

All this tests you are performing using the same submit button click?
and what does document.forms[1].action gives you?

Are you sure?
If that is not the case then I don't think there is any reason you get this error.
What values you get for document and document.forms[1]?
Try debugging what value of document or document.forms[1] you are getting.
Probably one of them is null, which is creating the problem.
Why do you set label value explicitly by calling a script?
The script you have encoded would not get called after refreshing by an ajax call.
I would suggest you write as below as it doesn't make any difference and serves your functionality

Do you have two forms on your JSP?
If no then you will need to use
