我有两个课程在各方面都相同但只有一个;第一个实现List<RuleSet>，而第二个实现List。他们拥有相同的成员和方法。当我尝试使用Netbeans＆＃39;来构建GUI时GUI构建器，我无法绑定到列表中的属性，而我可以绑定到另一个。
是否存在阻止我使用类实现PatternSet_I接口并将其用作Bean的东西？我这次可以解决这个问题，但这需要改变我的设计，我并不期望。
使事情更清晰的具体例子：
List实施PatternSet_J List没有实施PatternSet_I PatternSet_J List<RuleSet> 我将在下面添加代码：
PatternSet_I 实施package dvrminer.pattern;

，尽管其他方面相同。
PatternSet_I 测试是在NetBeans 8中构建的表单。它有一个PatternSet_J和一个JTextArea以及一个名为textArea的{{1}}。我可以将textArea绑定到patternSet_J1.pattern.name但不绑定到patternSet_I1.pattern.name。唯一的区别是patternSet_I1.pattern.name实现List<RuleSet>。
