No set method for property 'Value' in type 'CaptchaMvc.Models.CaptchaValueBase

Aug 15, 2013 at 9:11 AM
Hi,

I am using VS 2012, MVC 4 and on my page I have
@using CaptchaMvc.HtmlHelpers
@Html.Captcha("New characters", "Input character", 5 ,"Characters not correct", true)

I get the error message: "No set method for property 'Value' in type 'CaptchaMvc.Models.CaptchaValueBase'."

Any idea what is wrong?

Hi there,
Are you trying to serialize a CaptchaValue?
I ask this, because this error can occur if you try to serialize a property that does not have a setter. The CaptchaValueBase class has an error related to the serialization, I'll fix it in the next release.

Hi Yyacheslay,

Thank you very quick response!
I don’t know when the MVC 4 Azure WebRole is making serializing. I myself don’t intentionally serialize anything. Is this somehow related to the caching?
In my Web.config I have:
<caching>
  <outputCache defaultProvider="AFCacheOutputCacheProvider">
    <providers>
      <add name="AFCacheOutputCacheProvider" type="Microsoft.Web.DistributedCache.DistributedCacheOutputCacheProvider, Microsoft.Web.DistributedCache" cacheName="default" dataCacheClientName="default" applicationName="AFCacheOutputCache" />
    </providers>
  </outputCache>
</caching>
I tried to turn off the caching by adding an attribute to my Controller without any good:
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
Do you know when MVC framework is doing the serialization? Have you decided when the next release is going to happen and this issue is will be fixed.

The best,
risto

Hi Risto,

In your case the session is serialized and this is the cause of this error.
By the end of the week I'll release the new version, where the problem is resolved.
