[Geotools-gt2-users] Zoom_on_JMapPane_with_mouse_wheel

[iceDice <nmi...@gm...>]

Hello,

I am trying to implement zooming on mouse-wheel event on JMapPane and have
following problem:
In MapToolManager.mouseWheelMoved(MouseWheelEvent e) method i got that 
MapToolManager.convertEvent(MouseWheelEvent e) returns null for
MapMouseEvent sometimes.
I think that JMapPane.getScreenToWorldTransform() is returning null for
AffineTransform but 
i have no idea why this happens.

I hope so someone can help me about this.

Best regards.
