The probation violation is not directly associated with a criminal conviction - it does not even require a criminal act to rise to the level of a probation violation.
The probation office may decide that the actions are sufficient to warrant a probation violation. I once had a DV case where the local DA would not prosecute for the domestic violence, but a nearby county that held the probation felt the case was strong enough to justify a probation violation ... a court agreed.
If her probation officer wants to violate her, they will have to bring it back to the court and a judge will have to agree. In the meantime, she gets to sit in jail.
She needs to learn from this quick. She apparently got lucky in the recent jury trial, that may not happen again.
