阅读更多关于 How can I apply p:resetInput or p:ajax resetValue =“true” for p:dataList?

问题 All we know the problems of validation failed in JSF (take a look in here). Primefaces seems to resolve the problem with p:resetInput or p:ajax resetValue ="true" .

So, can anyone give me a solution? Thanks a bunch. More info: I tried update panel, dataLists, even every component inside, but it still doesn't work.
