Can you elaborate on what you mean by the above question - what steps are you going through when making changes? Do you run Tools - Update Libraries after making changes so that the in memory data is refreshed (or use the integraion traffic light at the bottom of the main xDX Designer window)?
Generally the tools are designed to pick up library changes when the project is opened, for instance if you have a user who acts as librarian and they make changes then the other users will see them when they invoke xDX Designer. In the case where you make the changes in the same session it is sometimes necessary to run the update manually.
If these suggestions don't answer your question then please provide more detailed steps as to your process (and please type messages in lower case, upper case my be interpreted as shouting).
Thank you Mr. Robert, my question has been answered
