As I understood, required="true" is needed to be sure that any hibernate validators specified will be run with s:validate(All).

But what about:
- if null value, I don't care (a value is optional)
- but if a value is written, it needs to respect a pattern, like no punctuation or no number inside the string

If I put a required="true" to get the hibernate validation in the second case, then the first case is always rejected by jsf.
