But in the meantime, you can use <mx:Window> and change them all to <s:Window> before you will finally build the release version of the project. 回答2: I am facing the same problem and it's very frustrating.

问题 I am trying to set up a translation service which will use gnu gettext. The basic idea is from: https://thedarkgod.wordpress.com/2009/01/18/java-webapp-localization-through-gettext/ But I would like it to be implemented as a service.
