Bug 169997 [CellEditors] TableViewer doesn't activate TextCellEditor consistently
A TextCellEditor is not activated consistently in a TableViewer if the cell clicked is not in the currently selected row. Running the sample application in a debugger, the bounds reported for the table item appears to be incorrect for the column when the row is not selected. This behaviour can be observed by setting a breakpoint at TableEditorImpl.java line 135 (the if statement doesn't return true unless the row is selected due to the bounds being incorrect): if (bounds.contains(event.x, event.y)) {
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/TreeViewer.java
((Tree) widget).clearAll(true);
			} else if (widget instanceof TreeItem) {
				((TreeItem) widget).clearAll(true);
			}
			int index = 0;
			Widget parent = null;
			if (widget instanceof TreeItem) {
				TreeItem treeItem = (TreeItem) widget;
				parent = treeItem.getParentItem();
				if (parent == null) {
					parent = treeItem.getParent();
				}
				if (parent instanceof Tree) {
					index = ((Tree) parent).indexOf(treeItem);
				} else {
					index = ((TreeItem) parent).indexOf(treeItem);
				}
			}
			virtualRefreshExpandedItems(parent, widget, element, index);
			return;
		}
		super.internalRefreshStruct(widget, element, updateLabels);
