Uncaught TypeError: Cannot read property 'getItems' of undefined

[Enter steps to reproduce below:]

From @sknorr below:

• first make sure Atom is closed
• do from the command line: atom --safe file1 && atom --safe file2. (Of moderate interest: using ; instead of &&, I can't reproduce this.)

@Misiak4 ftw, I was experiencing the same, but as of Atom 1.12.3, this seems to be resolved.

[sounakban]

I have version 1.13.0, and I am getting the same error.
I am running on Ubuntu 16.04LTS.

[rsese]

@sounakban 1.16.0 was just released today, can you update and let us know if you still see this error? And if so, please share steps to reproduce and let us know if you can reproduce in safe mode (atom --safe) - thanks!

[sounakban]

The issue seems to be resolved on version 1.16.0.
Thank you.

[rsese]

@michalurva or @rekurt, are either of you able to reproduce this error now after upgrading to 1.16.0?

[rsese]

@c0fe - I see you ran into this issue in 1.16.0 from your issue in atom/atom#14462. Is the error reproducible for you?

[c0fe]

@rsese I am trying but I think my issue is more of an edge case. It does happen from time to time and I am not sure what triggers it. I am trying to go back and see if I can figure out how it happens. I know the behavior of it.

Say, I have one file already open, then I go back to Explorer and select another file to be open through context menu (which how I open them all), it will on its own open in a new window and when I try to drag it in, then I get the error I got.

If I open other files, they open in the same window and selecting them to open in new windows and merging them again does not trigger the error.

[ahogen]

I just got this error. I double-clicked a Markdown file in Explorer which opened up the file in a new Atom window. I already had an existing Atom window up. I attempted to drag the Markdown tab in the new atom window to the old/original Atom window, like you might do it Chrome to merge tabs into the same window. This error popped up when release my mouse (dropping the tab).

Basically, this looks very similar to what @c0fe is describing.

[rsese]

Hmm, one difference I noticed is that you both mentioned that you have a window open and then opening a file from Explorer opens a new Atom window. For me, if I have Atom open, opening a new file from Explorer will open the file as a tab in the existing window.

[c0fe]

@rsese this varies from time to time, sometimes it opens a new tab and sometimes it opens a new window.

I can reproduce both the two-window behavior and the original issue on Atom 1.18/Linux: For me, Atom always opens two windows when starting Atom and opening two files in quick succession (you open the second file while Atom is still starting), e.g.

1. first make sure Atom is closed
2. do from the command line: atom file1 && atom file2. (Of moderate interest: using ; instead of &&, I can't reproduce this.)

When I then try to move one of the tabs to the other window, I get the original error.
