paging - grid is not reloading correctly

[kwasek]

Hi,
I have a problem with grid whem paging . I'll show my code :

Main class:

public class KontrahenciPanel extends ContentPanel{

public Grid<ModelData> grid;
public ColumnModel cm;
public ListStore store;
public PagingToolBar toolBar;

public KontrahenciPanel(){
cp=this;

ks = new KontrahenciStore();
listaRegionow=ks.getWszystkieRegiony();
listaTypowKontrahentow=ks.getTypyKontrahentow();
listaPracownikow=ks.getPracownicy();
setLayout(new RowLayout(Orientation.HORIZONTAL));
setBodyBorder(true);
setHeaderVisible(false);

setHeight((int)(Window.getClientHeight()-80));
createMenu(this);

this.add(makeGrid2() );


setButtonAlign(HorizontalAlignment.LEFT);

}


public void setFilterOnGrid(String filtr){
store = new ListStore(ks.getALLKonts(filtr));

grid.reconfigure(store, cm);

toolBar.bind((PagingLoader<PagingLoadResult<ModelData>>) grid.getStore().getLoader());

PagingLoadConfig conf = new BasePagingLoadConfig();
conf.setOffset(0);
conf.setLimit(100);
grid.getStore().getLoader().load(conf);



}

private void refreshEdit(Kontrahenci kont){
idkT.setValue(""+kont.getIdkontrahenci());
skrotT.setValue(kont.getSkrot());
nazwaT.setValue(kont.getNazwa());
ulicaT.setValue(kont.getUlica());
miastoT.setValue(kont.getMiasto());

regCMB.setValue(regCMB.getStore().findModel("idregiony", kont.getIdregionyFk()));

}

private void createMenu(ContentPanel panel) {

So.
Whem I launch app, grid is loading perfectly. When I click on 'nowy' and

KontrahentEditWND kwnd = new KontrahentEditWND(cp);
kwnd.show();

is fired ( KontrahentEditWND is a class extended with Window ) and then I close it and refresh the grid using refresh button on paging toolbar, or click next or prvious page, the grid is not reloading properly. I mean for example I click next page. Toolbar and grid are grey and after a while toolbar is properly refreshed but the grid is still greyed. When I click again on next page , both of them are refreshing correctly.

Any ideas?

Dude, don't understand me wrong, but your code is a totally mess!

Why do you create a new ListStore every time you filter a data??
You could extend the ListStore and add a custom filter method to it.

Every time you create a new store to your grid, you must reconfigure it. Take a look at grid.reconfigure function.

Take a look at some design patterns, it may help you with code organization.

I hope it can help.
