问题 I have two variables "userId" and "name". When I click for example the "SHOW USERID" button it works fine and sets "renderUserId=true" and it shows it with the "render", but then if I click the other "SHOW" button, the Bean is reconstruct and I loose the "renderUserId=true" and it becomes "false" and "renderName=true" so it shows ok, but the USERID is hidden.

I can't seems to find a concise guide to doing this anywhere!

[Edit]: My goal is to get the posted form data - Not to get the generated html code (Sry I wasn't precisely) 回答1: It is unclear what you want to achive, yet. I mean, at high level. UIComponent.decode and processUpdates are medium-level lifecycle APIs which
