Hi Jerritte,

I ran into similar issues a while back when creating a pretty large form.  I don't recall the exact fixes, however you should try using Fiddler when you visit the entries page, and look for any 500 errors you are receiving, then view the Raw Data - this should give you an error message that explains the problem.

If I recall the maxJsonLength and/or the maxQueryStringLength needed to be increased in the web.config to be able to handle all the fields when calling the records webservice. 

If not post the error here and we should be able to figure it out.  I think there was another issue also but maybe if you post the error it'll jog my memory  :)

Hope this helps,
Tom

Tom,

Awesome -- thanks for the quick reply! You just reminded me that one of my developers started to go down this path at one point, but didn't follow through on it (I think because he thought he found the issue elsewhere, and then forgot to look back into this issue after that). I'll check into these suggestions and get back to you.

Thanks!
Jerritte

Tom,

OK, I've increased the maxJsonLength in the Web.config to 2147483647 (the largest JavaScript int...just for testing). The problem didn't go away. I checked out the page using Fiddler, and it says there's a 404 error for this URL:

I'm not quite sure what would cause a 404 error, though.

Any thoughts?

Thanks,
Jerritte

Hi Jerritte,

OK, I took a look at the old install I had this problem with.  There were two steps I needed to do, in addition to increasing the maxJsonLength:

- Increase the maxQueryStringLength in web.config - system.web/httpRuntime

<httpRuntime requestValidationMode="2.0" maxQueryStringLength="5000" />

- Override the default maxQueryString Request Limit - system.webServer/security/requestFiltering/requestLimits

<system.webServer>
  <security>
    <requestFiltering>
      <requestLimits maxQueryString="500000"/>
    </requestFiltering>
  </security>  
  ......
</system.webServer>

I was able to reproduce & fix the issue with the above, so I think this will do the trick for you.

FYI - the 404 was actually a 404.15, if you had detailed errors on you probably would have seen the cause :)  (The request filtering module is configured to deny a request where the query string is too long.)

Hope this helps,
Tom

Tom,

Thanks SO much! The httpRuntime didn't work for me. I think it must be for a newer version of Umbraco (I'm running 4.5.2 on .NET 3.5, and I think this is for .NET 4.0).

However, the maxQueryString setting did the trick!

I really, really appreciate your help with this. Your quick responses helped me knock this out just in time. :)

Thanks!
Jerritte
