Data cube from Ginga to Glue gives IndexError about glue-ginga

[ejeschke]

@pllim, we may need to rework the way the data is put into the glue dataset when it is transferred. In the case of a cube or higher dimension, we probably need to pass more than just the current slice so that the metadata matches up. I haven't tested this yet, but you probably can replace the image.get_data() here with something like image.get_mddata().

I'll hold off on the release until we check whether this simple fix (or something like it) does the trick.

That worked, then, @pllim?

@ejeschke , unfortunately only partly. See #26 (comment)

Also I uncovered #27 while testing #26.
