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.

if ( image.getLocalProperty( getModule( ),
							(PropertyDefn) image.getDefn( ).getMember(
									EmbeddedImage.DATA_MEMBER ) ) != null )
					{
						byte[] data = base
								.encode( image.getData( getModule( ) ) );
						String value = new String( data, EmbeddedImage.CHARSET );
						if ( value.length( ) < IndentableXMLWriter.MAX_CHARS_PER_LINE )
							writeEntry( DesignSchemaConstants.PROPERTY_TAG,
									EmbeddedImage.DATA_MEMBER, value, false );
						else
							writeLongIndentText(
									DesignSchemaConstants.PROPERTY_TAG,
									EmbeddedImage.DATA_MEMBER, value );
					}

					assert false;

				writer.endElement( );

			writer.endElement( );
