Hi,

As shown in the link:
AJAX based CRUD tables using ASP.NET MVC 3 and jTable jQuery plug-in

I created a simple application. I created the database first and created Model in the application using the edmx file.

At first, there was only one table (parent) and the application was working correctly.

Then, I added another table (child) in database and updated the edmx file.

Thereafter, the previously working screen began to show error and the message is "An error occured while communicating to the server".

Please advice, Thank you.

There is no problem with the edmx I think, the problem is with the connection. Try validating the edmx first.

With the two tables application still works when the relationship is deleted from edmx and database. Validation shows completed without errors.

Verify the url you are trying to pass

Dis you check the key relationship!! Coming correct in the edmx diagram??

Keys are coming correct. Now I've discared the jtable, going with default razor. :(

Thats also a good move..:) you can also use GridMvc
Thats easy and nice also just you need to pass the data from server.

The problem seems to be in this case that the constructed JSON object also contains the relation to the collection of child object(s).
jTable does not seem to understand this.

When you create a new class with the column properties only and copy all values across, the table will work again, but then the real benefit of using jTable is gone...
