Many thanks for your hint. It did solve the problem
My orginal code make a dirty flag at commitProperties() that image load only once at first time. After your hint, I remove the loading code out and the problem has been solved. Thanks
However performance wise, the image blind and reload whenever I scoll the tilelist, how can I
a/ make the scrolling process more smoothly
b/ the image still in the screen ( no blind and off ) whenever I scroll the tilelist
Thanks and hope to hear your hint again
Apart from the question above, I also have an question about the tileList.
As my source of tileList is ArrayCollection, I make the filterfunction on the ArrayCollection which filter the display inside the tilelist.
But the defaultTileListEffect do not affect on filterfunction, how can I apply the defaultTileListEffect on filterfunction also.
