Known issues in Device Preview

This section describes the known issues in Device Preview.

Session cookies need to be cleared
Problem: When you are using targeting functionality in the Experience Manager, the Ambient Data Framework caches the device User-Agent in the session. Consequently, when you try to load another device in Device Preview the different User-Agent is not updated in the session cookie.
Solution: Create a file which clears the session cache when a new device is loaded.
After upgrading, icons are missing from the Devices view
Problem: After upgrading to SDL Tridion 2013 SP1, the Devices view shows no icons for specific devices.
Solution: Manually copy the folder DeviceIcons\, containing the device icons, and the folder DeviceImages\, containing the device images, including all of those folders' contents, from %TRIDION_HOME%\web\WebUI\Editors\DevicePreview\Themes\Carbon\Images\ to %TRIDION_HOME%\web\WebUI\Editors\DevicePreview\Themes\Carbon2\Images\.
Metadata fields are not editable in Device mode
Problem: In Device mode, metadata fields may not be editable; they appear in a popup with the background (and also the background's scrollbars) greyed out.
Solution: You can edit these fields in Desktop mode.
Continue Editing Later fails after Switch to Desktop from Format Area
Problem: You may lose changes made in a Format Area (Rich Text Field) if you do the following:
  1. Edit a Format Area field in Device mode
  2. Press Switch to Desktop on the toolbar
  3. Select Continue Editing Later
Solution: To work around this problem, switch to the desktop mode:
  1. Edit a Format Area field in Device mode
  2. Press Device Preview on the toolbar
  3. Select Desktop
  4. Select Continue Editing Later

Device Preview is unable to work with a URL that requires query string parameters
Problem: Device Preview produces the following error when trying to open a URL that ends with a query string, for example, http://www.example.com/page.aspx?q=test "System.ArgumentNullException: Value cannot be null." :
