Workfile: error during saving if context not fully initialized

[antirotor]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior:

When using Workfile tool:

if you click on Save button before the content of the folder and task menus is loaded, workfile tool crashes with the traceback below

Expected Behavior:

Save button shouldn't be available until everything for it is ready.

Version

1.0.0

What platform you are running on?

Windows

Steps To Reproduce:

You need to somehow simulate slow server response. In my case it happens in Mocha Pro where there is something really slow. Anyway:

• Open workfile tool and click on Save As before folders and tasks load (show in menus)

Are there any labels you wish to add?

• I have added the relevant labels to the bug report.

Relevant log output:
