问题 PrimeFaces has very well done filter for p:dataTable. It is great from UX site, because the filter field is in column header, so there's no doubt what you are filtering, and it's working live - the data changes as you type (well, only if you make a short pause, but it's in my opinion exactly what user expects). Now I'd like to place something custom in the header that would act as filter. So, my idea was to place a component in header facet: <p:column ...> <f:facet name="header"> <some

问题 I'm interested can I store into client side for example large hashmap or a List?

All JSF as being a HTML code generator can do for you is to print Java objects in JSON format as a JavaScript variable assignment
