I must agree that Caesar simply 'being away in Italia' seems a poor reason for a revolt - indeed, no reason at all, but rather a time of opportunity.

I would have to agree that Caesar's actions while on campaign had much to do with the revolt, as did the mere fact that they had just been conquered in a short period of time, if you could call it conquering. Naturally they would revolt, given the fact that they did not go willingly into the Roman realm...
