Hilites do not match gird data
All I want to do is color the entire row, based on one field.
I reworked your Simulated Stock Quotes Example in the EE showcase to use hilites.
First a button to launch a window
Click the button -> launch window 0 -> The servlet turns on updates for the next 90 seconds -> the updates go into the datasource -> the data updates -> the hilites update.
wait for the updates to end.
Click the button -> launch window 1 -> The servlet turns on updates for the next 90 seconds -> the updates go into the datasource -> the data updates -> the hilites update in all windows ( in window 1 they are correct. Window 0 they are not.)
wait for the updates to end.
Click the button -> launch window 2 -> The servlet turns on updates for the next 90 seconds -> the updates go into the datasource -> the data updates -> the hilites update in all windows ( in window 2 they are correct. Window 0 and window 1, they are not. )
The end state of the hilites for windows 0 and 1, is normally wrong (green rows with negitive change values, or red rows with positive), and windoww 1 doesn't match window 0.
The latest window, the hilite state is correct.

Code:
IButton button = new IButton("launch window");
button.addClickHandler(new ClickHandler()
{
int count = 1;
@Override
public void onClick(ClickEvent clickEvent)
{
new GuiWidgetLab("window" + count++).show();
}
});wait for the updates to end.
Click the button -> launch window 1 -> The servlet turns on updates for the next 90 seconds -> the updates go into the datasource -> the data updates -> the hilites update in all windows ( in window 1 they are correct. Window 0 they are not.)
