Does appellant timely appeal from the judgment of conviction in this case?

9 In this case, appellant points out that she did in fact timely appeal from the judgment of conviction in this case, at least from that portion of the judgment by which the trial court refused to allow her to withdraw her guilty plea. Because she did not raise any sentencing issue, she has waived any objection to the term of imprisonment initially imposed in this case. That does not mean, however, that she is foreclosed from challenging the order revoking probation and directing execution of the previously suspended four-year prison sentence. (People v. Harty, supra, 173 Cal.App.3d at p. 501, 219 Cal.Rptr. 85.)
