I have a chart that was converted from 2005 with dundas to 2008 r2. All looks fine except the colours (a normal thing in conversion by the looks of it).
So if i deploy to the server - its fine. However i noticed that the bar in the chart used to be sligtly transparent (to see line behind). So i changed the colour to transparent. All works in VS so i deploy.
However when deployed it errors saying "object reference not set to an instance of an object."
If i remove transparancy then deploy again it works fine.....
