visual studio 2012 - Lightswitch "Object reference not set to an instance of an object" error -

-

i following error when try save in lightswitch application. "object reference not set instance of object"

i have published application different computer.

but when publish same computer on developed, works perfectly. think missing here.

the error means you're trying use not defined or not initialized @ moment.

if works in dev machine not on deployed machine; it's highly possible did wrong deployment.

try debug , understand difference between configurations. if can't debug on deployed computer, better write log somewhere , understand variable giving error.
