Class Cast Exception While Using Map Component

[saharhassan]

I have a Map component on my detail band. I have set the Latitude as 12.58 (Just plain value, no Java expression) and 77.38 as Longitude. When I click Preview button, it is throwing me this exception:

Hi.

 

I have solved the issue myself.

 

I gave the value for Latitude as 12.58f and Longitude as 77.38f.

Voila! It works and gave me Bangalore's Map.
