只需按照某些人的要求重复上述UPDATE:

Just repeating the above UPDATE as asked by some people:

已使用 http://osdir.com/ml/jstree/中的说明进行了解决2011-04/msg00126.html .显式列出所有有效子代(而不是使用"all")解决了这个问题.

Solved using instructions in http://osdir.com/ml/jstree/2011-04/msg00126.html . Explicitly listing all valid children (instead of using "all") solved the problem.

明天我将检查jsTree问题页面中是否存在类似的错误，也许还会添加一个新错误.

I'll check whether a similar bug is filed in jsTree issues pages tomorrow, maybe adding a new one.

还是谢谢.
