I create a GraphicsOverlay and put a advanced symbol on it. This is done using a DictionaryRenderer (MIl2525D)
The task "identifyGraphicsOverlays" is done on a sidc "10032500001406030000" // SymbolSet/Entity = 25 140603
(line with arrow)
The slot "identifyGraphicsOverlaysCompleted" is called but with an empty result list :-(
Many (maybe all) multipoint sidcs can´t be identified/picked.
