To achieve OverviewMap with Custom Tiled Layer Type

Discussion created by zju.fengtian on Jun 27, 2011
Hey, guys!

I'm handling with the problem as the title says.
According to the JavaScript API Reference, the valid type for base layer of OverviewMap excludes Custom Tiled Layer Type. I tried achieving this functionality, but resulted in failure.

I was wondering whether it's available to use overviewmap with custom tiled layer.
Thanx for concentration.
