I am trying to write my own Remote DTED Layer so far i managed to show
elevation data while pressing butoon but while invoking getRectangle
(where the OMGraphicList is prepared i get such exception....
*** ERROR ***

I am curious about the serialization process of OMGraphicList - can i in
some way convert all OMGraphicList elements in some kind of raw image
data lets say GIF or JPEG??
Perhaps transfering such data and retriving the image on the client side
should help.
Any Ideas.??
