TST: devdeps broken because _mouse_click_cb creates canvas object with coord being None about astrowidgets HOT 4 CLOSED

I think that is due to a very recent change in CanvasObject where a canvas object's coord attribute used to default to 'data' but now defaults to None. But None will assign a data mapper when the object is added to a canvas--so the result is still the same. The reason for change was to allow the user to set a coordinate mapper for the canvas and have objects inherit that if they don't assign their own.

You can safely change that assertion to:

assert circ.coord in (None, 'data')

from astrowidgets.

Sorry for the confusion!

You can also assign coord='data' when creating the Circle, if you prefer, and keep the assert as it was. That is probably preferable, because you are being explicit about what mapping is being used to draw the object when you create it.

Thanks, @ejeschke !
