在用wicket实现过滤表格中加入表单 这样的功能时，达不到预期效果。非常高兴Igor给出了说明和建议：
filter toolbar was not meant to be embedded in another form because it uses a form of its own, so for right now i would say that usecase is not supported. please add an rfe for it.
if you want one right now then you have to create your own variant that doesnt use an embedded form. it would be pretty much a copy and paste job of the current toolbar but w/out the form.

再一次感谢Igor，每次都是这位老大帮我解决相关问题。
