Is a failure to address a triable issue of fact a harmless error?

We note that plaintiff complains under a separate heading in her appellate brief that the trial court failed to refer specifically in its order to the evidence indicating that a triable issue of material fact exists as required by Code of Civil Procedure section 437c, subdivision (g). Such a failure is harmless, however, "`since "`[i]t is the validity of the ruling which is reviewable and not the reasons therefore.'"' [Citation.]" (Byars v. SCME Mortgage Bankers, Inc. (2003) 109 Cal.App.4th 1134, 1146 [trial court's failure to address cause of action on summary judgment was harmless error where appellant failed to present evidence to raise a triable issue of fact].)
