RAD工作区在启动/ RAD许可证冲突上的错误

Question

我开始使用RAD并且我的工作区中充满了错误。

☞我在我尝试在工作区中打开的每个现有.java文件上都出现此错误。

---

☞我爬现有.xsl文件此错误。

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

我做了一个工作区clean并重新启动RAD与-clean但错误依然出现！对于如何解决这个问题，有任何的建议吗？

Answer 1

人，看来问题出在license configuration for RAD。最近，我的工作站上的许可证从Floating切换为Permanent许可证，然后桌面团队重新分配了永久安装并删除了浮动安装任务。当发生这种情况时，Installation Manager was confused on which license to use。当浮动许可证被禁用时，它拿起了永久许可证并让我摆脱了所有的错误。感谢我们的系统工程师！

希望这可以帮助别人！
