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/ViewerColumn.java
* call the super implementation.
	 * 
	 * @param labelProvider
	 *            the new {@link CellLabelProvider}
	 */
	public void setLabelProvider(CellLabelProvider labelProvider) {
		setLabelProvider(labelProvider, true);
	}
	/**
	 * @param labelProvider
	 * @param registerListener
	 */
	void setLabelProvider(CellLabelProvider labelProvider,
			boolean registerListener) {
		if (listenerRegistered && this.labelProvider != null) {
			this.labelProvider.removeListener(listener);
			listenerRegistered = false;
			if (registerListener) {
				this.labelProvider.dispose(viewer, this);
			}
		}
		this.labelProvider = labelProvider;
		if (registerListener) {
			this.labelProvider.initialize(viewer, this);
			this.labelProvider.addListener(listener);
			listenerRegistered = true;
		}
	}
