> myfaces in Production stage:
> <f:validateBean>
> <h:outputLabel>myfaces</h:outputLabel>
> </f:validateBean>
> (or book.xhtml in myfaces-jpa test app)
> In every request/response, this invocation appears:
> MetaRulesetImpl.<init>(Tag, Class<?>) line: 118
> ComponentTagHandlerDelegate.createMetaRuleset(Class) line: 459
> HtmlComponentHandler(DelegatingMetaTagHandler).createMetaRuleset(Class) line: 102
> HtmlComponentHandler.createMetaRuleset(Class) line: 42
> HtmlComponentHandler(MetaTagHandler).setAttributes(FaceletContext, Object) line: 63

> ComponentTagHandlerDelegate.apply(FaceletContext, UIComponent) line: 235
> HtmlComponentHandler(DelegatingMetaTagHandler).apply(FaceletContext, UIComponent) line: 53
> ValidatorTagHandlerDelegate.apply(FaceletContext, UIComponent) line: 152
> ValidatorHandler(DelegatingMetaTagHandler).apply(FaceletContext, UIComponent) line: 53
> this applies for all children of f:validateBean
> Without f:validateBean Metatag rules are created only once in production stage during initial request to facelet.
> (Not sure if it is a bug - maybe something special needs to be done for f:beanValidator )
> It also leads to stack bellow - but _getFactory method is synchronized and slow down response times to the same facelet:
