When a Grid control has no items and is created a virtual, an exception is thrown
Here's a cut down version of the Grid Example that reproduces the problem:
public class NebulaGridExamplePage implements IExamplePage {
public void createControl(Composite parent) {
parent.setLayout(ExampleUtil.createGridLayout(1, true, true, true));
ExampleUtil.createHeading(parent, "Profit and Loss Balance Sheet", 1);
parent.setLayoutData(ExampleUtil.createFillData());
Grid grid = createGrid(parent);
GridColumn column = new GridColumn(grid, SWT.LEFT);
column.setWidth(100);
}
private Grid createGrid(Composite parent) {
Grid grid = new Grid(parent, SWT.V_SCROLL | SWT.BORDER | SWT.VIRTUAL);
GridData tableLayoutData = ExampleUtil.createFillData();
tableLayoutData.verticalIndent = 10;
grid.setLayoutData(tableLayoutData);
return grid;
}
}
The exception thrown:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Non-virtual grids work fine. Should I raise this in bugzilla?
