I considered this solution, but I'm afraid my data-structure is a bit to complicated, to do something like this (it's not as simple as I discribed - there are some vectors involved and so on ;-) and in addition I shouldn't solve the problem this way.
I had related problem with an datatable and checkboxes (instead of a selectOneMenu) and I could solve this problem with a binding to UIData and UISelectBoolean. (You have this binding of your DataTable and you can iterate through its rows and you can check with the UISelectBoolean in each row, if the checkbox is checked or not) I thougth I could solve my actual problem in a similiar way (binding to UIData and UISelectOne or something like that) - but it doesn't work, like I thought. I would be glad, if anyone could explain, how to do this binding or how to approach the problem in another way (the datatables model or something). But if not, I'll try an approach as you proposed.

I have a similiar problem too, in that the User objects are (ideally) just provided to me, but as they stand they do not have a 'roleId' property (or more succinctly a 'isSelected' property). For quickness I actually added this property to each User object. Since the alternative, as far as I'm aware at the moment, seems to be to have an intermediate or decorative class object, where you iterate over the given Users objects and create a new decorative class instance for each User which will contain this roleId property and use this new List of objects as the dataTable value binding, which isnt very elegant but it would seem anything else would be even less elegant. Someone else might know of alternatives.
