查看 xml 个文件时 Eclipse 出现奇怪的错误

Question

使用 XML 编辑器打开 xml 文件时，我在 IBM RAD 中遇到以下错误：

An error has occurred. See error log for more details.
Aborted cyclic load attempt for model with id: /Example/src/com/example/resources/example-config.xml

打开错误日志显示同一错误的多个实例：Unhandled event loop exception

查看错误有以下堆栈跟踪：

我正在使用 IBM RAD v 8.0.4.2，它使用 Eclipse 3.6.2。

我希望这是一个简单的配置问题，我不需要重新安装，因为我在公司环境中工作并且获取软件 installed/re-installed 很痛苦。

此错误与 Eclipse 中的此错误相似

https://bugs.eclipse.org/bugs/show_bug.cgi?id=332238

它已在 Eclipse WTP 3.3.2 中修复，但 RAD 8.0.x 使用 WTP 3.2.5。我的建议是，如果可能的话，至少升级到 8.5，否则您将需要联系 IBM 支持
