Bug 150776 Binding parameters of datasources are not evaluated when datasource in a library
I used to defined a datasource with binding parameters (depending on parameters ...). It works well when datasource is defined in the report, but when i tried to put this datasource in a library, binding expressions are not evaluated or not used by the datasource. When debugging the code, two datasources appears, the initial from the library (module=Library) and the linked from the report (module=ReportDesign). The dataset used the datasource of the report, but no binding values are found on the report datasource. The datasource from the library is evaluated correctly but not used.

	{
		
		DesignElement element = getElement( );
		Object value = element.getProperty( module, propName );
		if ( value instanceof ReferenceValue )
			return ReferenceValueUtil.needTheNamespacePrefix(
					(ReferenceValue) value, getModule( ) );
		PropertyDefn defn = (PropertyDefn) getPropertyDefn( propName );
		if ( value instanceof List && defn != null
				&& defn.getSubTypeCode( ) == PropertyType.LIST_TYPE )
		{
			List valueList = (List) value;
			List names = new ArrayList( );
			for ( int i = 0; i < valueList.size( ); i++ )
			{
				ElementRefValue item = (ElementRefValue) valueList.get( i );
				names.add( ReferenceValueUtil.needTheNamespacePrefix( item,
						getModule( ) ) );
			}
			return names;

		return value;
