Google Maps 1.8.0 breaks TileReceiver's ReceiveTile callback

[kochizufan]

Hello,

I use Google Maps component 1.8.0 from component store.
But in this version, TileReceiver's ReceiveTile callback does not work.
It does not cause any error, but tiles are not shown.

This method worked well till 1.7.2, so now I use 1.7.2.

Can fix this problem?
