once you understand models it becomes quiet trivial :)
below is the simple way (without using a compound property model)
class mypage extends webpage {
private user user;
private logtype logtype;
// getters setters (only necessary in 1.2.x, in later wicket will access
private properties through property model)
public mypage() {
form form=new form();
add(new DropDownChoice("users",new PropertyModel(this, "user"),....));
add(new DropDownChoice("logtypes", new PropertyModel(this,
"logtype"),...));
add(new DataView("results",new MyDataProvider(),...
...
private class MyDataProvider implements IDataProvider {
public Iterator iterator(int f,int c) {
return getlogs(user,logtype);
}
}
}
and thats all she wrote. makes sense?

The popilateItem as i know it is used within the dataview. That part i
understand. let me re-explain myself.
on my webpage class, i have a dataview component. i also have a
dropdownview
component . they are both children of a form component. i have a beans
user,
log and logtype. (I am using wicket along with spring.). now in my webpage
i have a drop down class whic implements dropdownchoice. the list for the
drop down is generated earlier in the webpage class. i have a drop down
for
the user. and a drop down for the log type. I want to get the user
selection
for these two, tie it back to the appropriate bean then set those beans in
the implementation of the dataprovider then use the implementation of the
data provider as the model for the dataview. My problem lies is getting
the
user selection from the drop down. I can't seem get it without having a
model to tie it to.
