Cannot put 2 symbols on the same point on GraphicsLayer

[takashiiwata]

hi,

I'm trying to put 2 symbols with infoWindow on GraphicsLayer to show searching result by QueryTask,

but it always shown 1 symbol on 1 point even put different GraphicsLayer as well.

I want to show 2 pages of infoWindow on the same point.

is that possible to show 2 symbols on the same point on the GraphicsLayer?

if anyone has idea, plz help.
