  Example on world documentation for partialrouting doesn't seem to work when deployed to servers

When you use GetChildren without specifying a language (a LanguageLoaderOption) then the language is resolved from the context. In case of a normal web request, that language is determined from the URL (either through host mapping or language segment). However an initializable module is likely to run outside a normal webrequest, so in that case language is resolved using other available sources, like globalization element in web.config. To ensure a deterministic behavior, you should explicitly specify a language when loading content from an initializable module. (You can use a fallback to master or use LanguageLoaderOption.MasterLanguage() or LanguageSelector.MasterLanguage if you do not know the language beforehand.)

  [Segment_v2.0]: Returns 500 Server Error when input a negative number in param with profile filter definition

Steps to reproduce:

  1. Create a profile filter definition with params being number data types (int, long, double):
  "Name": "Int_data2",
  "Description": "Number equal a value",
  "Query": "Payload.number eq {{value}}",
  "Parameters": {
    "value": "int"
  "Category": "Profiles",
  "Type": "Profiles"

-> Create successfully

2.  Create a segment with filter definition in step 1 and insert a negative number in param like this:

  "Parameters": {
    "value": -2

Expected result:

Returns 201 Created.

Actual result:

Returns 500 Internal Server Error.

Note: It does not occur in the event filter definition.

  Language manager should handle nested blocks when importing or exporting xliff

In the following scenario, the Title field from the PageHeaderBlock would appear in the exported data, but not the AltText or Caption from the ImageBlock that it was using as a property.

Page :: GenericPage

  • Block :: PageHeaderBlock
    • String :: Title
    • Block :: ImageBlock
      • String :: AltText
      • String :: Caption
  • ContentArea :: Content

  Add configuration options for Activity Log Truncation to avoid timeouts

The Activity Log truncation would frequently fail with the following error, so configuration options were added so that you can control the maximum number of activities that are removed, and specify a custom timeout for the database command execution.

One or more errors occurred. [Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.]

You can now use the following settings in the ActivityOptions class in the Episerver.Cms.ActivityOptions section.

  • TruncateMaximum. Sets the maximum number of activities to remove.
  • TruncateDatabaseTimeout. Sets the timeout of the database command.

  Define custom metadata for media types without using attributes

Add the possibility to define custom metadata for media types without using attributes (ImageDescriptorAttribute, MediaDescriptorAttribute) to better enable headless projects.

Metadata defined with attributes should be handled as before, but metadata defined through the API should be stored in the database. When resolving these values the information in the database should be used primarily, if no database values exist for these fields they will be resolved using the attributes as before. The metadata includes:

  • Properties from the ImageDescriptorAttribute
  • Properties from the MediaDescriptorAttribute
