ListGrid Filter Editor Initialization

[romain.vdk]

Hi everybody,

I have another question I cannot solve ...
I make a simple listgrid, and on the page loading, I cannot use the fliter (no call is made at all), unless I hardcode a first call to my datasource. Is that the way the things must work, or is there something I missed?

Here is the listGrid generation code :

ListGridField ituCode = new ListGridField("itucode","Itu Code");
		ituCode.setFrozen(true);
		ituCode.setWidth(120);
		ListGridField lastStatus = new ListGridField("lastStatus","Last Status");
		lastStatus.setAlign(Alignment.CENTER);  
		lastStatus.setType(ListGridFieldType.IMAGE);
		lastStatus.setImageURLPrefix("status/");  
		lastStatus.setImageURLSuffix(".gif");  
		lastStatus.setImageWidth(32);
		lastStatus.setImageHeight(24);
		lastStatus.setFrozen(true);
		lastStatus.setWidth(75);
		ListGridField terminals = new ListGridField("terminals","Departure Terminal<br/>Destination Terminal<br/>Final Terminal");
		terminals.setWidth(150);
		ListGridField fullOrEmpty = new ListGridField("fullOrEmpty","Full/Empty");
		fullOrEmpty.setWidth(100);
		ListGridField weights = new ListGridField("weights","Net Weight (kg)<br/>Gross Weight(kg)");
		weights.setWidth(150);
		ListGridField statusDate = new ListGridField("statusDate","Status Date");
		statusDate.setWidth(200);
		ListGridField departureDate = new ListGridField("departureDate","Departure Date");
		departureDate.setWidth(200);
		ListGridField actors = new ListGridField("actors","Invoicing<br/>Sender<br/>Receiver");
		actors.setWidth(250);
		ListGridField refNumbers = new ListGridField("refNumbers","Customer Ref<br/>Operator Ref");
		refNumbers.setWidth(200);
		ListGridField controlNumbers = new ListGridField("controlNumbers","Ctrl train Number<br/>Railway train number<br/>Wagon number");
		controlNumbers.setWidth(200);
		
		listGrid.setFields(ituCode,lastStatus,terminals,fullOrEmpty,weights,statusDate,departureDate,actors,refNumbers,controlNumbers);
		listGrid.setWidth100();
		listGrid.setHeight("300px");
		listGrid.setHeaderHeight(50);
		listGrid.setCellHeight(50);
		listGrid.setDataPageSize(50);
		listGrid.setAutoFetchData(true);
		listGrid.setShowFilterEditor(true);
		listGrid.setFilterOnKeypress(true);
		listGrid.setDataSource(dataSource);

And here is the dummy call I have to do to make the filter work :

Criteria c = new Criteria();
		dataSource.fetchData(c,new DSCallback () {
			public void execute(DSResponse response, Object rawData, DSRequest request) {
				listGrid.setData(response.getData());
			}
		});

Thanks for your replies!
