Sitefinity 4.1 SP1 Upgrade Considerations

May 17, 2011 Digital Experience

If you haven't already heard, the Sitefinity 4.1 SP1 has been released. It is an essential upgrade and we encourage all our customers to install this update as soon as possible.

For help upgrading, be sure to check the Sitefinity 4 upgrade documentation as well as this previous post: Upgrading Sitefinity 4 Websites.

Changes

Sitefinity 4.1 SP1 includes a few changes to be aware of before upgrading.

Content Module Fluent Mapping Changes

If you are using Fluent Mapping in your custom content-based modules, there is an important change that was made.The ContentBaseMetadataSource base class no longer implements a parameterless constructor which will cause an error if you attempt to build a content-based module project.

To fix this, in your derived class, instead of calling the removed constructor, call the default constructor with a null value.

Change this:

public MyModuleFluentMetadataSource() : base() { }

to this:

public MyModuleFluentMetadataSource() : base(null) { }

Your project should now build correctly.

Saving Configuration Changes

If you are using the API to add or remove elements from the various Sitefinity configuration files, you may notice that your changes are not automatically persisted. In addition, if you attempt to use the SaveChanges() method of the configuration manager you receive the following error:

This method is not supported by Telerik.Sitefinity.Configuration.ConfigManager. Please use SaveSection() instead.

Instead of calling SaveChanges(), you must instead call SaveSection() passing into it the section parameter that you're modifying. For example, the following code would remove a custom widget from the toolbox configuration.

var configMgr = ConfigManager.GetManager();
var config = configMgr.GetSection<ToolboxesConfig>();
var pageControls = config.Toolboxes["PageControls"];
var section = pageControls
       .Sections
       .Where<ToolboxSection>(e => e.Name == ToolboxesConfig.ContentToolboxSectionName)
        .FirstOrDefault();
if (section != null)
{
      // remove widget if it exists var widget = section.Tools.FirstOrDefault<ToolboxItem>(e => e.Name == "MyControl");
      if (widget != null) section.Tools.Remove(widget);
}
configMgr.SaveSection(config);

Lost Content After Upgrade

If after upgrading, your content is lost, or if you have duplicate controls that appear on the page that do not appear in edit mode, please review this KB article for a fix: Lost content after 4.1 upgrade

Duplicate Control IDs

After upgrading you may receive an error similar to the following:

Compiler Error Message: CS0102: The type 'ASP.sfpageservice_d12edd17_5884_46ab_a1bf_6d1f87e7b8aa_inforetail_aspx' already contains a definition for 'C000'

OR

Parser Error: The ID 'C001' is already used by another control.

For a fix, please see this KB Article: Duplicate control IDs after upgrading to Sitefinity 4.1
