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.

if ( binding == null && value == null )
			return;
		if ( bindingList == null )
		{
			assert value != null;
			bindingList = new ArrayList( );
			root.setProperty( Module.PROPERTY_BINDINGS_PROP, bindingList );
		}
		defn = root.getPropertyDefn( Module.PROPERTY_BINDINGS_PROP );
		assert defn != null;
		PropertyCommand cmd = new PropertyCommand( module, root );
		if ( value == null && binding != null )
		{
			
			cmd.removeItem( new CachedMemberRef( defn ), bindingList
					.indexOf( binding ) );
		}
		else
		{
			/*
			 * If the property has no binding related to, adds a new binding
			 * item into the structure list.
			 */
			if ( binding == null )
			{
				binding = new PropertyBinding( );
				binding.setName( propName );
				binding.setID( getID( ) );
				binding.setValue( value );
