What is the application platform? What code is it written in? Does it record anything, at least the "Keys" method and the parameter is blank?
You can edit the recording after the fact and fill in the value fields manually. In fact, this is a best practice. It is generally not a good idea to rely, purely, on what is recorded. It's a good way to start creating a test case, but manual edits, updates, etc., are pretty much required in order to make sure a test case is robust and stable.
While this does not address the problem with the text not recording, there is a sufficient work around until we get more information about what you're attempting to test.
