Today I did some test develope via tech of JSF, and had met a problem liked that, when I submit the commonButton,the form couldn't be submit to the manageBean,and I was mazed, I thougth that maybe I had ignored some config which was requied. When I read the document of the JSF,I found the config was hundred-percent. So I didn't knowed why, and after that,I copy the code which has made well-balanced funcions to the jsp,It don't work accurately too, so I thought some inaccurate code of this current jsp  affected this, so I finally found I had multiSelecteCheckBox data binding error, I repaired this error finally.
But this thing show that the skill of my solving problem ought to be improve. In really, I can find the point  which the error occured, the form cannot be submitted, first I must think out that is maybe occured on the data verify!
