[求助]关于Appfuse中Form的scope问题	2006年05月15日 09:08
标签列表

最近用Appfuse（JSF，1.7.2版本）做个小型项目，有几个Master-Detail类型的Form因为要保存中间状态，故打算将<managered-bean-scope>设置为session，可惜改变之后一旦Save就报错。
不知哪位同道有办法解决此类问题？在此先谢过了。

>Master-Detail类型的Form因为要保存中间状态
面向模型编程，应该是Master-Detail类型的Model，这样将Model存入缓存就没有什么问题。

非常感谢banq的回复。
为此我又试了一下一般的Form，即Save没有任何关联的Model，在scope为request的时候全正常，一改成session还是报错，实在是相当苦恼。再次请教。

顺便附上错误信息：
