Description

System Information
Windows 10

Blender Version
Broken: 2.78.4, don't know since when

Short description of error

If an operator is called by API, Operator.report only prints to console, but does not output the report to the UI (info)

The result is a serious restriction that you can only display warnings

  • either directly out of an operator, but not out of defs where self is not passed
  • or after displaying a dialog popup

of course, if there is an alternative method to display mag's in the info bar, this report is invalid - but I didn't find any

No bug here, code called from py console reports errors in py console, as expected, no reason to clutter general UI from there.

In general, if you want to report something from an operator, then you have to pass the operator object (self) around, that’s by design (or at least, self.report callback).
