Dinamic selectItems

[Krstian117]

Hi all
I am working whit primefaces, hibernate and JSF
i have a problem

i have two selectOneMenu, they load values from a list, the list is the result of a query with two columns (example: Select i.id,i.name From test i)

In the xhtml, in the first selectOneMenu load the list in the field [1], need to show the column 2
in the second selectOneMenu load the list in the field [0], need to show the column 1

i need that when select a value in the selectOneMenu 1, automatically the selectOneMenu 2 change

example

selectOneMenu1
selecteditems = list[1] ---- list = name1,name2,name3,name4,name5
selectOneMenu1

selectOneMenu2
selecteditems = list[0] ---- list = 1,2,3,4,5
selectOneMenu2


When in the selectOneMenu1 selected name3, the selectOneMenu2 change to id 3

Please help
