[RaEditor] Document Manager displays 'There was an error in the callback' message.

[Yuriy]

Hi,

I am using Telerik.Web.UI rev 2011.1.315.35. I have met a strange issue — opening the Document Manager and navigating to one specific folder causes Document Mamanger to display the following error message:

There was an error in the callback.

This happens only with one item in the content tree. Clicking on it results in the mentioned error message displayed, and the subfolders of this folder are not expanded, though they are displayed in the middle pane. Could you please provide me with some assumptions on how to fix this?

Hello,

Could you please upgrade to the latest Q3 2011 SP1 build and try to reproduce the problem again?

Hello Rumen,

Unfortunately, I cannot upgrade to the latest build as we are using Telerik's controls as a part of Sitecore CMS. Is it possible to obtain a hotfix somehow?

Thank you in advance.

Best regards,
Yuriy.

Hello,

I am not sure which version of RadEditor (RadEditor.dll or Telerik.Web.UI.dll) is used by Sitecore, but we do not directly support this CMS.

You can contact their support and ask them for help to upgrade the editor to its latest version or try yourself using binding redirect to upgrade the editor.

If the old RadEditor.dll is reference by another SiteCore assembly you should configure assembly binding redirect in the web.config file:

<dependentAssembly>
<assemblyIdentity name="RadEditor" publicKeyToken="852c9eb6525c1b53" culture="neutral" />
<bindingRedirect oldVersion="1.0.0.0-7.3.6.0" newVersion="7.3.6.0" />
</dependentAssembly>

You can find more information in the following MSDN article: Assembly Binding Redirection.

The same is true if the Telerik.Web.UI.dll is used:

<dependentAssembly>
<assemblyIdentity name="Telerik.Web.UI.dll" publicKeyToken="852c9eb6525c1b53" culture="neutral" />
<bindingRedirect oldVersion="1.0.0.0-2011.3.1305.35" newVersion="2011.3.1305.35" />
</dependentAssembly>
