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.

libLabel1.setText( "ccc" ); 
		libraryHandle.save( );
		designHandle.reloadLibrary( libraryHandle );
		libraryHandle = designHandle.getLibrary( "Lib1" ); 
		libLabel1 = (LabelHandle) libraryHandle.findElement( "libLabel1" ); 
		assertEquals( "bbb", libLabel1.getText( ) ); 
		assertEquals( "bbb", label1.getText( ) ); 
		SimpleMasterPageHandle page = (SimpleMasterPageHandle) designHandle
				.findMasterPage( "My Page" ); 
		assertEquals( 1, page.getPageHeader( ).getCount( ) );
		libLabel1 = (LabelHandle) page.getPageHeader( ).get( 0 );
		assertEquals( "ccc", libLabel1.getText( ) );
