im looping the values of a collection into a foreach and i want to create datatable as loops. but i need to filtered the rows that would have each datatable with the current value of the foreach, how can i do that?

i have the methods that fill the foreach with a collection, and i have the methods that give me the collections for the datatable, the question is this:

how can i pass the current value of a foreach to a managedbean for filter what collections return using that value.

im using jsf with primefaces, and i have my models with hibernate im using criterias to return the collections.
