Hi,
I am trying to implement dataview:
final IDataProvider<PostDomain> postDomainDataProvider = new
IDataProvider<PostDomain>() {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void detach() {
// TODO Auto-generated method stub
}
@Override
public int size() {
// TODO Auto-generated method stub
System.out.println("Data view size called");
try {
return list.size();
} catch (Exception exception) {
// TODO Auto-generated catch block
exception.printStackTrace();
return 0;
}
}
@Override
public IModel<PostDomain> model(final PostDomain
object) {
// TODO Auto-generated method stub
return new
LoadableDetachableModel<PostDomain>() {
/**
*
*/
private static final long
serialVersionUID = 1L;
@Override
protected PostDomain load() {
return object;
}
};
}
@Override
public Iterator<? extends PostDomain> iterator(int
first, int count) {
// TODO Auto-generated method stub
System.out.println("Dataview iterator called");
try {
return getList(count, first).iterator();
} catch (PostNotFoundException
postNotFoundException) {
postNotFoundException.printStackTrace();
} catch (Exception exception) {
// TODO Auto-generated catch block
exception.printStackTrace();
}
return null;
}
};
Now what is happening is size() method is getting called many times before
dataView is rendered. There is no looping situation over
here and if there would be any infinite looping, then dataView wont have
rendered.
size() can return any thing from 0 to 100..and I have set
dataView.setItemPerPage(20).
What can be the reason?
