Forcing datasource to refresh grid row.

[johndow777]

Hi,
I am using gwt comet to push data into my grid data source. I have a collection of all records added to the data source and when some data arrives i update the appropriate record from the collection with record.setAttribute("fieldtoupdate", pushedValue). But this does not update the grid. I need to call :
grid.refreshRow(grid.getRecordIndex(record)) in order to update the ui grid. All this is happening in the data source and i have :

public class UpdatableListGridRecord extends ListGridRecord implements UpdateListener {
	
	private ListGrid grid;
	
	public UpdatableListGridRecord(ListGrid grid) {
		this.grid = grid;
	}

	@Override
	public void update(double pushedValue) {
		this.setAttribute("pushedValue", pushedValue);
		grid.refreshRow(grid.getRecordIndex(this));
	}

}

But in order to use this i need to have reference to the grid object in my data source, which is not correct. So any ideas how from the data source i can tell the grid to update it's record?
Regards.

Generally, you would use the Registration design pattern so that anyone can call a method to get notified when a successful DataSource change happens.
