AjaxFallbackDefaultDataTable - goto page number on return from another page
Wicket 1.3.4.
I have a Page (ThingListing) containing an AjaxFallbackDefaultDataTable -
created like:
private WebMarkupContainer listContainer = new
WebMarkupContainer("listContainer");
private MySortableDealProvider dataProvider;
private Thing thing = null;
public ThingListing(PageParameters params) {
// this is a reload from the CRUD page
if (params != null) {
setThing(getThingManager().findById(params.getString("thingId")));
}
// else load everything
...
dataProvider = new SortableDealDataProvider(getThingManager(), thing);
String sort = params.getString("sort");
Boolean isAscending = params.getBoolean("ascending");
dataProvider.setSort(sort, isAscending);
...
listContainer.add(new AjaxFallbackDefaultDataTable("mything", columns,
dataProvider, TABLE_ROWS));
I add an AbstractColumn to the AjaxFallbackDefaultDataTable to handle
forwarding to a page to do CRUD work on the selected item from the table -
like :
columns.add(new AbstractColumn(new Model("Edit")) {
public void populateItem(Item cellItem, String
componentId, IModel model)
{
cellItem.add(new ActionPanel(componentId,
model));
}
public String getCssClass() {
return "edit";
}
});
class ActionPanel extends Panel {
public ActionPanel(String id, IModel model) {
super(id, model);
add(new Link("edit") {
public void onClick() {
Integer thingId = ((Thing)
getParent().getModelObject()).getId();
PageParameters params = new
PageParameters();
params.put("thingId", thingId);
params.put("sort",
dataProvider.getSort().getProperty());
params.put("ascending",
dataProvider.getSort().isAscending());
setResponsePage(ThingEdit.class,
params);
}
});
}
}
Note - I am attempting to pass the id of the selected row in the table, plus
the sort column, and the ascending direction to the CRUD page.
The ThingEdit CRUD page takes all the page params from the ThingListing
page, does normal CRUD work, then passes back all the params back into the
main listing page constructor so that when the listing page reloads, it
maintains its state (main selection criteria, sort column, sort order) from
the page the user selected before triggering the CRUD page - eg:
public class ThingEdit {
private PageParameters pageParams;
public ThingEdit(PageParameters p) {
pageParams = p;
...
}
...
private void addCancelButton(Form form) {
Button cancel = new Button("cancelbutton") {
public void onSubmit() {
setResponsePage(ThingListing.class, pageParams);
}
};
cancel.setDefaultFormProcessing(false);
form.add(cancel);
}
However, I can't work out how to go back to the page number that the user
was on before he loaded the CRUD page. That is, if the user was on page 3
of 20, then after clicking a record to edit goes to the CRUD page, then he
goes back to the listing the correct order and sort are maintaine, but he's
always at page 1 of 20 instead of page 3.
I have tried manually setting the ThingSortableDataProvider.iterator() first
and count and with additional page params - but this just ends up with it
being called twice - once with my page params, and again by the default 0
and count.
So, any way to make this work?
I think am probably still missing the point with Wicket (can't really get my
head around Models) and revert to attempting to use page params and manually
adding to session to pass data from one page to another and back again.
