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.

					ContentException.DESIGN_EXCEPTION_HAS_NO_CONTAINER );
		ContentCommand cmd = new ContentCommand( module,
				element.getContainerInfo( ) );
		cmd.remove( element, false );
	}

	 * Drops this element from the design. Removes the element from its
