Unusual error on submit/AJAX

Hi all -

Strange error here. I have a screen with two blocks within it, that have a lot of data in them. A link on the screen is set to either "Submit" or "Ajax" (problem occurs both ways) and in some situations, I get this error when it is clicked. In fact, anything that does a postback (like a notification for an autocomplete component) produces the error. Any idea what could be wrong?

Thanks!

Hi Justin,

That error is caused by a security protection on the Asp.Net side. ( http://technet.microsoft.com/en-us/security/advisory/2659883 )
It prevents DoS attacks by limiting the number of post fields.
The default maximum is 1000.

To fix your problem you can either simplify your page or increase the limit.

To increase the limite you would need to add a setting to your web.config
(Not sure if it works at the web site level of needs to be on the application web.config):

<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="<new value>" />
</appSettings>

I did it, and now it totally killed the server.

I went into the IIS configuration editor, added the entry at the site level, and it started giving errors about licensing (see below). I undid the change and the error persists. The licensing page says that everything is fine. I cannot make the change in the application level web.config, because the publishing process will wipe it out, so it needs to be made at the Web site level.

Hi Justin,

From the error message I see you have 6.0.1.10. That version has known licensing problems.
I recommend you to update to the latest version.

The error itself is not related to the setting.

Joao -

Luckily, it was fixed (we tried re-uploading the license, then rebooting, that fixed it).

We will try updating to a later version, thanks!
