hey @skratchdot thanks for point this out, will have a look 👍

jccguimaraes · 2017-04-21T18:29:43Z

@skratchdot can you confirm this still happens in the 1.0.13? thanks

skratchdot · 2017-04-21T18:56:18Z

@jccguimaraes - it still seems to be happening for me in 1.0.13:

skratchdot · 2017-04-25T12:43:48Z

@jccguimaraes - the gif is kind of bad because it starts after I had clicked my "Recent" project- and the UI was kind of hanging until the first red error showed up. Then I clicked a second project and the second red error showed up. So anytime I want to switch projects now, I have to restart Atom (e.g. I can only use the project that is selected when Atom opens- if I switch to a new project- nothing works and I have to restart Atom).

jccguimaraes · 2017-04-26T00:03:36Z

@skratchdot you are using beta channel right?

skratchdot · 2017-04-26T00:24:06Z

@jccguimaraes - yes, that's correct: the beta channel.

jccguimaraes · 2017-04-27T09:40:58Z

@skratchdot 1.17.0 is breaking PV, so i am investigating it. I think it's mainly because tree-view as changed a lot.

skratchdot · 2017-04-27T15:56:46Z

No worries. Just figured I'd let you know.

jccguimaraes · 2017-04-27T15:59:19Z

that was well spotted mate

jccguimaraes · 2017-04-30T23:26:28Z

i have read in the code where the problem occurs the following

// Ensure deserializing 1.17 state with pre 1.17 Atom does not error

So I have a small fix/hack but it will keep files open switching between projects (if that's ok) i can make that fix until a better solution exits (in 1.16) it ain't breaking

skratchdot · 2017-05-01T01:44:37Z

I'm fine with that behavior (but can't speak for all your other users)! Thanks again for this project.

jccguimaraes · 2017-05-01T07:41:46Z

published the hack into 1.0.14. hope it smooths the problem.

skratchdot · 2017-05-02T01:50:38Z

it's working for me! thanks @jccguimaraes!
