這幾天在用Netbeans6.1RC1 發(fā)現(xiàn)了一些問題，不知道大家有沒有遇到呢？問題如下：
1.在新建一個桌面應(yīng)用程序的時候 最后一步點擊Finish以后就會跳出兩個對話框，說“TestView.java被修改過了，是否重新載入”讓你選擇是否重新載入
如果你點擊了yes 當(dāng)你運行程序的時候就會出現(xiàn)下面的異常，
如果你點擊No就不會出現(xiàn)問題了
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

2.還有個問題是關(guān)于
JSF的，是在
Netbeans中文社區(qū)里有人提出來的，在NetBeans6.0.1版本中可以實現(xiàn)
組件的自動綁訂但是在6.1RC1里就不行了，必須要右鍵組建選擇Add Bingding Attribute 我覺得這應(yīng)該是一個bug，下面是截圖。
我原本以為在NetBeans6.0.1中可以完成的 在NetBeans6.1中應(yīng)該也是可以完成的，后來自己測試的時候才發(fā)現(xiàn)并不是我想象中的那樣。
這是NetBeans6.0的官方JSF的教程連接
http://www.netbeans.org/kb/60/web/helloweb_zh_CN.html
用Netbeans6.1RC1做的時候就會出先下面的問題。
注意：下面的
TextField1.gettext();方法中
TextField1是在沒有改變IDE自動生成的代碼的前提下寫的,有興趣的朋友可以幫忙測試一下！
好了今天就寫這么多吧，明天繼續(xù)寫關(guān)于學(xué)習(xí)國際化的內(nèi)容！
