[OpenMap Users] Radius error when editing an OMCircle

Hello Folks!

I am currently playing around with the editing stuff in OpenMap and I
ran into this.
I place an OMCircle on the map and creates it as this;

        OMCircle circle = new OMCircle( lat, lon, position.getRadius(),
Length.METER );

adds the circle to the layer and everything works perfectly.

I save the circle reference because I want to know the changes.

When the user has edited it I gather the data in a custom class and send
it to a server, but when I look at the radius it is not the correct
value. eg 400 meters become 0.0035 ... =(

I have traced it to when I ask for the radius on OMCircle ( OMArc ) it
converts the radians with Length.DECIMAL_DEGREE.fromRadians( float ) and
not the length unit I sent in. This calculation makes the radius almost

Is this a bug or am I using the classes wrong?

Should the getRadius method take a Length class to convert the rads to
the correct value??
