addToolButton behavior in Acrobat DC

[BfloKen]

Our publishing clients use specialized features we've added to PDF documents in the form of JavaScript calls to 'app.addToolButton' as described in adobe Javascript design documents.

With Acrobat Pro DC (2015 continuous release), the floating window appears (as it should), AND we now find tool bar buttons added to the right-side under 'Add on Tools'. When customers see the same buttons in two locations (the floating window and the tools panel) --- they may dismiss the Javascript window.

But when users open 'comment tools' to annotate the document, and then dismiss the 'comment tool', the Add on Tools and custom buttons are gone.... as are all the controls we had added to manage server workflow. This is not good.

What is the definitive (current) document that describes how 'addToolButton' works? What do we do to keep the custom buttons present in the Add-on Tools pane?

Thanks

After snooping around a bit more - it looks as though my current issue, while not exactly the same problem - may be related to other problems with the tools panel losing track of add-on tools:

app.addToolButton in folder level script creates a floating Add-on Tool bar in Acrobat Pro DC

I have filed a bug report regarding our disappearing add-on tools (described above) with Adobe --- but also see the bug shown above as not being answered.

Is anyone looking at this stuff?

Yes, it's a seriously annoying bug in Acrobat DC that Adobe hasn't solved yet. Let's hope someone is working on it other there...
