P: ActiveHistoryState after changing activeDocument doesn't work at all

[lukaszmtw]

I have a script, which basicly changes activeDocument to doc_a, then it changes activeDocument back do doc_b and tries to check activeDocument.activeHistoryState here. It always stops executing here and I get "General Photoshop error occured. This functionality may not be available in this version of Photoshop.". Any ideas how to solve this?

The code for reproducing this bug: (I'm using CC 2015.5.1, but it doesn't work on CC 2014 either)

app.activeDocument = app.documents[0];  
app.activeDocument = app.documents[1];  
$.writeln(app.activeDocument.activeHistoryState);

Hello this is a bug.  Sorry.  As a work around please try this.

app.activeDocument = app.documents[0];  
app.activeDocument = app.documents[1];  
app.refresh();
$.writeln(app.activeDocument.activeHistoryState);

This works, but it adds unwanted delay. Any ETA for a fix?

[David Dobish]

Yes it does add a delay.  I do not have a ETA right now.  

As a side note:

We are not seeing the error on Windows.  So you can use a Windows machine if you want to not use the app.refresh

Is it likely to be fixed in the next PS release?

[David Dobish]

I would say that we are looking into it.  Other than that I cannot comment on when a specific fix is coming.  Sorry to be nebulous.

Thanks!

Try with CC 2017. I believe we fixed this issue.
