Gavin,
I extended your ListDataModel for this and used @Out instead of @DataModel. My
extension provides the methods used for pagination and sorting and, in doing
so, attempts to manipulate the super classes attributes (rowCount, rowIndex and
wrappedData). The exception I'm getting is:
attempted to bind an Out attribute of the wrong type to:
userSearchAction.paginator
Everything works fine up until Seam attempts to outject it. Maybe I'm
misunderstanding how your code works. Is it not simply outjected as a
ListDataModel?
Here is the relevant code:
My Seam action
public class UserSearchAction implements UserSearch
| @Out(required=false)
| private ListDataModelPaginator paginator;
| ...
| Query query = em.createQuery(query);
| paginator = new ListDataModelPaginator(query.getResultList());
| paginator.sort(ASC_NAME_COMPARATOR);
| ...
| }
Paginator
| public class ListDataModelPaginator extends ListDataModel {
|
| private int rowsPerPage = 20;
|
| public ListDataModelPaginator() {
| super(new ArrayList());
| }
|
| public ListDataModelPaginator(List list) { super(list); }
|
| public ListDataModelPaginator(List list, Comparator comp) {
| super(list);
| }
|
| public void scrollFirst() {
| setRowIndex(0);
| }
|
| public void scrollPrevious() {
| setRowIndex(getRowIndex()-rowsPerPage);
| if (getRowIndex() < 0) {
| setRowIndex(0);
| }
| }
|
| public void scrollNext() {
| setRowIndex(getRowIndex()+rowsPerPage);
| if (getRowIndex() >= getRowCount()) {
| setRowIndex(getRowCount() - rowsPerPage);
| if (getRowIndex() < 0) {
| setRowIndex(0);
| }
| }
| }
|
| public void scrollLast() {
| setRowIndex(getRowCount() - rowsPerPage);
| if (getRowIndex() < 0) {
| setRowIndex(0);
| }
| }
|
| public boolean getIsScrollFirstDisabled() {
| return getRowIndex() == 0;
| }
|
| public boolean getIsScrollLastDisabled() {
| return getRowIndex() >= getRowCount() - rowsPerPage;
| }
|
| public boolean getIsScrollNextDisabled() {
| return getRowIndex() >= getRowCount() - rowsPerPage;
| }
|
| public boolean getIsScrollPreviousDisabled() {
| return getRowIndex() == 0;
| }
|
| public int getRowsPerPage() {
| return rowsPerPage;
| }
|
| public void setRowsPerPage(int rowsPerPage) {
| this.rowsPerPage = rowsPerPage;
| }
|
| public void setSortedList(List items){
| super.setWrappedData(items);
| super.setRowIndex(0);
| }
|
| public void sort(Comparator comp){
| List unsorted = (List)getWrappedData();
| Collections.sort(unsorted, comp);
| super.setWrappedData(unsorted);
| super.setRowIndex(0);
| }
| }
