Yes I believe that I did what the documentation describes.
I setup the environment as described in the documentation and run the build all script, after that I copy the ear file to the deploy library and I can access the workspace, but it is still in english. I am not sure why this happens...
Can anyone give me a short description of what the minimum procedure of localizing the workspce looks like?
You will need to set up Flex SDK, ant, import the New Workspace ES project, and then modify your build.xml file. You will need the LiveCycle_ES_SDK folder from LiveCycle server (also accessible from Workbench ES after you connect to the LiveCycle server. When you import the new Workspace project (Flex project), it should be pointing to the Flex SDK in the default location. You may need to modify the build.xml file for your environment. When you access your Workspace, are you using the new URL? I'm presuming that your browser settings for locale are set to Danish as well?
If you want, you can send a ZIP of the project to firstname.lastname@example.org
