Ken Koellner @ Engageware set error message in lightning.
I'm working on a lightning component that will run on both a quick action and in a VF page. I know toast doesn't work when the component is in VF. It appears showNotice() doesn't either.
Is there a prefered way to put up an error message when the component is run both from LEX and via VF?
The use case is the component does a call to an Apex aura controller and certain conditions can't be fulfilled, it returns a message. The messasge instructs the user on what they have to fix before they resubmit.
I considered just putting a message on a field for this specific error but it concerns a lightning:select and, unlike lighting:input, lightning:select won't let you put a custom error on it.

force:showToast It doesn't say anything about classic or VF, so you have to manually implement toast using SLDS.
