Grid sorting problem [GXT 2.1.1 with GWT 1.7.1]

[lhanusiak]

In my application I use grid with store data loaded by RPC proxy.

private final BeanModelReader beanReader = new BeanModelReader();
private final UserProxy proxy = new UserProxy();
private final BaseListLoader<ListLoadResult<BeanModel>> loader = new BaseListLoader<ListLoadResult<BeanModel>>(proxy, beanReader);
private final ListStore<BeanModel> store = new ListStore<BeanModel>(loader);
private final Grid<BeanModel> browser = new Grid<BeanModel>(store, createUserColumnModel());

private class UserProxy extends RpcProxy<List<ApplicationUserDTO>> {
		private Department department;

		@Override
		protected void load(Object loadConfig, AsyncCallback<List<ApplicationUserDTO>> callback) {
			userService.getADUserList(department, callback);
		}

		public void setDepartment (Department department) {
			this.department= department;
		}
	}

Because loaded data have to be sorted by selected column I tried

browser.getStore().setDefaultSort("lastname", SortDir.ASC);

and... it doesn't worked. So I started to dig in GXT source code and found

public class ListStore<M extends ModelData> extends Store<M> {
 ...
     @SuppressWarnings("unchecked")
     protected void onLoad(LoadEvent le) {
        ...
        if (storeSorter != null) {
             applySort(true);
        }
        ...
     }
 ...
}

Full of hope I added following line ...

browser.getStore().setStoreSorter(new StoreSorter<BeanModel>(StoreSorter.DEFAULT_COMPARATOR));

but as I soon realized, grid doesn't sort data at all. It has sorting indicator visible but data are displayed in totally random order.

After further reading I found ...

public class ListStore<M extends ModelData> extends Store<M> {
 ...
     @SuppressWarnings("unchecked")
     protected void onLoad(LoadEvent le) {
        ...
        if (le.<Object> getConfig() instanceof ListLoadConfig) {
         ListLoadConfig config = le.getConfig();
         if (!Util.isEmptyString(config.getSortInfo().getSortField())) {
          sortInfo = config.getSortInfo();
         } else {
          sortInfo = new SortInfo();
         }
        }
        ...
     }
 ...
}

... and finally added...

loader.setSortField("lastname");
loader.setSortDir(SortDir.ASC);
loader.setReuseLoadConfig(true);

Form this moment grid sorting worked just fine.

I would like to know if is there any easier way to sort data in grid than adding all of the following lines every time

browser.getStore().setDefaultSort("lastname", SortDir.ASC);
loader.setSortField("lastname");
loader.setSortDir(SortDir.ASC);
loader.setReuseLoadConfig(true);
store.setStoreSorter(new StoreSorter<BeanModel>(StoreSorter.DEFAULT_COMPARATOR));

Thanks in advance.

P.S. Sorry for my English, I am still learning.

Try setting sort info in loaderConfig passed to proxy load method
