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.

* Returns a handle to the element that contains this element. Every element
	 * except the report design has a container. The container of a parameter,
	 * shared style, data source or data set is the report design itself. The
	 * container of a report item is the section or other report item in which
	 * it appears.
	 * 
	 * @return a handle to the container element.
