  • Have you tried to see what `event.target` returns? How about adding a click handler within the item renderer and dispatching a bubbling event? – J_A_X Jul 26 '11 at 20:51

You're using imgCount to access the index of your ArrayCollection; however, you always set it to 0.

You could change s:DataGroup to s:List, then use the selectedItem property in your click handler:

image.source = dg.selectedItem["image"];

  • it is not worked error:Multiple markers at this line: -Access of undefined property selectedItem -1119: Access of possibly undefined property selectedItem through a reference with static type spark.components:DataGroup. – Rajkamal Jul 27 '11 at 05:40
  • Sorry - you are right. imgCount issue remains the same, but you could use s:List instead of s:DataGroup and access the selectedItem. – Jason Sturges Jul 27 '11 at 13:37
