componment hierarchy changed between rendering and form submission

[Giovanni <pi...@yahoo.com>]

I have a form used for performing a search on a database.

If I fill the form and then I submit it for the search and wait until the results appear, it works well.

The search takes some seconds (5-10 seconds).

Instead, if I change some fields, dropdown choices, checkboxes on the form after clicking on the submit button and before the result appear, I get the following error:

Unexpected RuntimeException

Is there anybody who can explain me this error and give me some suggestions, in order to avoid it?

Best regards,
giovanni

We really couldn't help without seeing the code.  Look at the highlighted
section of the message (below) - which you also used as your subject.
Apparently something is changing the component hierarchy.  Could something
be changing the model that effects which options show in your check group?

Ignore the typo "componment" - which I just fixed in trunk.
