We are presently refactoring our JSPs to JSFs. Some problems we have faced with JSFs are as mentioned below.
1. Cache: When we make a change to any
JSP it gets automatically reflected when we call that JSP. In case of
JSF the window needs to be closed and then reopened to reflect that change. I think this is related to the JSF cache.
2. JSFs seems to be slower than JSPs.
3. Does JSFs support NOWRAP in tables?
These are a few of the problems we faced.
