the id of dropdowns has nothing to do with their model. i am not using a
compound property model anywhere in the code, nor am i not specifying it
directly.
the model for each dropdown is specified as a propertymodel where "this"
refers to the page and the string refers to the property on that page.
so the selected user object will go into the "user" page property, and the
selected logtype will go into the page's "logtype" property just like the
property models specify.
then your dataprovider picks up those two properties and uses them to filter
the result just like the code shows.
the models are just glue between formcomponent and properties on some java
bean - which in this case happens to be the page.

let me make sure i understand..
add(new DropDownChoice("users",new PropertyModel(this, "user"),....));
the Property model returns the User model. and the id of this
dropdownchoice
is used to access that model? so get or setUsers on the User user of this?
if that is correct. can i do add(new DropDownChoice("users",new
PropertyModel(mydataprovider, "user"),....)); and get a model that is a
property over there set to something?
let me give a bit more detail..
I have a filter in my dataprovider that searches my DB using a service
that
takes users and logTypes and returns a list. thats why i need to set them
in
there. I have a list of all the users tied to a list and all the log types
tied to a list in the web page. i just want to take the once selected and
hand it to the dataprovider who will give me back a list of all the
process
matching those 2 models it was given. I understand what you said but just
need some clarity on weither or not it would work in the way i am doing
it.
or is there another way i should be approaching the problem. Thank you for
you repeated assistance.
