Hi Marcel,
Glad you could solve this. Model id/name is the name used when setting it to a control. Like oChart.setModel(oModel,"ModelName"). If name is used, then it should be used in binding as well. Like "{ModelName>/VALUE}". If
I am assuming you have some sort of master-detail application. Ideally you should refresh model bound to the chart with new data when new master list item is selected. onAfterRendering is called only once in a views lifecycle.
