Hi ruthwik,

Have you confirmed that the error is coming from the display method you added?

Because the error is saying different thing.

Can you debug and confirm it?

If the error is coming from the display method, debug and see exactly at what line the error is throwing.

Thanks,

Girish S.

This is a standard piece of code where the error is throwing.

But we are asking in display method - At which line the error is throwing in the display method you have written.

Thanks,

Girish S.

Then I think its not because of display method. Have you done any other customizations.

If you comment the display method is it throwing error?

Thanks,

Open details of the exception and look at the stack trace. This should show give more details that you've collected to far.

The error itself is saying that you're trying to assign a form to a variable that can hold tables only, but it's important to know where it happens.
