Insert row in datatable (JSF 2 + Richfaces 4)
Hello guys,
I am trying to insert a row in a datatable. In fact, What I want to do, It is an "editable" datatable. Users should be able to see displayed data in table, insert new rows, or edit rows. All that within the table, I dont wan' t to use pop-up modal forms or another kind of forms outside the table
Mu backing bean is @SessionScoped
This is the source code pf my JSF page:
