Uncaught TypeError: Cannot read property 'getSelections' of null

[Enter steps to reproduce below:]

1. close minimap using [cmd]+[shift]+[p] -> "minmap: toggle"

Really I did nothing different than my usuarl toggling of the minimap. Don't know why it failed this time.

System: Mac OS X 10.10.1
Thrown From: minimap-selection package, v3.1.1

as a side note.... If I close the exception notice window on atom and click on the main edit buffer I get the error again.

Closing and openning atom stopped this from happening.

Thanks for your ansewer @fundon but i'm consistently getting the error now with minimap v4.1.3 and atom happily states that All your installed packages are up to date!

I can now reproduce de problem by starting atom, toggling the minmap off and trying to edit the buffer.

This did not happen prior to updating my packages... this morning. I think minmap did not update and it worked yesterday.

I guess it is some conflict with some other package.

EDIT: BTW leaving minmap open does avoid the problem.

I can now reproduce de problem by starting atom, toggling the minmap off and trying to edit the buffer.

The toggling issue was fixed in minimap v4.1.1. atom-minimap/minimap#255.

You can disable the minimap-selection, the minimap-selection has some compatible problems with the Minimap V4.

[abe33]

The issue was caused because the plugin didn't destroy its views when a minimap was destroyed (which occurs on minimap toggling)
