我正在 netbeans 上测试一个 primeFaces CRUD 生成器。
网站：用于 NetBeans beta 的 PrimeFaces CRUD 生成器
当您按下 Create.xhtml 页面的保存按钮时，actionListener 不起作用。编辑行时也会发生同样的情况。Glassfish 错误日志中没有任何内容，firebug 上也没有任何内容。
测试：
- 插件版本：nbpfcrudgen-0.15.2-7.3.1impl.nbm
- Ubuntu 12.04 64 位
- Netbeans NetBeans IDE 7.3
- Primefaces 3.5
- GlassFish Server 开源版 4.0
- 火狐 22.0
- mysql 5.6.11
您可以观看测试视频：
