NetBeans
这几天在用Netbeans6.1RC1 发现了一些问题，不知道大家有没有遇到呢？问题如下：
1.在新建一个桌面应用程序的时候 最后一步点击Finish以后就会跳出两个对话框，说“TestView.java被修改过了，是否重新载入”让你选择是否重新载入
如果你点击了yes 当你运行程序的时候就会出现下面的异常，
如果你点击No就不会出现问题了
init:
deps-jar:
Created dir: D:"BackUp"My Documents"NetBeansProjects"TestApp"build"classes
Compiling 3 source files to D:"BackUp"My Documents"NetBeansProjects"TestApp"build"classes
Copying 22 files to D:"BackUp"My Documents"NetBeansProjects"TestApp"build"classes
compile:

2.还有个问题是关于
JSF的，是在
Netbeans中文社区里有人提出来的，在NetBeans6.0.1版本中可以实现
组件的自动绑订但是在6.1RC1里就不行了，必须要右键组建选择Add Bingding Attribute 我觉得这应该是一个bug，下面是截图。
我原本以为在NetBeans6.0.1中可以完成的 在NetBeans6.1中应该也是可以完成的，后来自己测试的时候才发现并不是我想象中的那样。
这是NetBeans6.0的官方JSF的教程连接

用Netbeans6.1RC1做的时候就会出先下面的问题。
注意：下面的
TextField1.gettext();方法中
TextField1是在没有改变IDE自动生成的代码的前提下写的,有兴趣的朋友可以帮忙测试一下！
好了今天就写这么多吧，明天继续写关于学习国际化的内容！
