Bug 176436 Charts Imported from Libraries do not update when libraries change
During a live presentation of BIRT at EclipseCon, we came across a rather embarassing issue. When charts are included in a library, and imported into a report design from a library, any changes to the library instance of the chart do not reflect in the report itself.

						assert item instanceof ElementRefValue;
						refValue = (ElementRefValue) item;

						{
							propHandle.addItem( refValue.getElement( ) );
						}
						else
						{
							propHandle.addItem( refValue.getQualifiedReference( ) );
						}
					}
				}
				break;
			default :
				targetHandle.setProperty( propName, value );
