there is an EntityManager which has a method persist, you can call it in a for-each loop with each entry of the list as its parameter, ;-)
thanks a lot for your answer, now that I turned to work with a selectManyCheckBoxes (which i don't know if it is better or not) but I still dont know how to store the selected rows into my database!
You suggested me to loop in order to store the list but how can I do that...Please If you can show an example I'll be veeery grateful :)
Sorry to be so unpolite (that was the reason for a smilley in my answer). If you don't understand the basics of persisting somthing as simple as a numberof entities, you need some seriois study before you proceed with Seam. I recommend to look at Hibernate/JPA first (that's were the entityManager comes from).
The Seam documentation (on your left on this page) a lot of matarial to study. Besides the docs, the Seam distribution contains a directory with alot of examples. And last but not least, there is an excellent book Seam in Action which will help you a lot.
Actually I'm very new in the whole Java environnement that's why I'm asking those kind of questions.
Thanks for your help
