first of all the dataprovider is a readonly interface, it has no set method
like the model.
that said what you want is simple:
populateitem(item item) {
final imodel namemodel=new propertymodel(item.getmodel(), "name");
add(new dropdownchoice("names",namemodel,nameslist));
}

i see....i have a fair understaning of models this is what i am doing: I
have
a dataprovider that services a dataview. this data provider is the the
model
that i ultimately need to update. however the properties within this are
beans i need to set them using the selection from the dropdown. so fo
instance....my dataprovider has a property that is a saya user. this user
itself has a property called name. which is a string. now in my webpage
class i have a dropdown with a list of names. what i need to do is select
a
name and get the appropriate bean to pass it to the dataprovider so that
it
can do its thing and return its results to the dataview. how would i go
about this?
