public ConstantsWithLookup getFieldPropertiesInterface() {
return (ConstantsWithLookup)GWT.create(AtollProperties.class);
//AtollPojo:81
}

AtollProperties extends ConstantsWithLookup

On the client side this, when my form creates an AtollPojo there is no
error. When form is submitted, i create another instance of AtollPojo
(on the server side) but gives the above error.

ie: works on client side but does NOT work on the server side? help
please :(
