Auto-Require Mis-Mapping ctors in async

[Kitson Kelly]

In certain scenarios it seems the parser is mis-matching constructors when running in async mode.

I am investigating the root of the defect and the attached examples will demonstrate the issue. When run in async, there are issues with the TabContainer and when async is turned off, the page renders properly.

BTW that test file is working fine for me.... oh wait nevermind, I see I need to edit the file to set async:true.

adding debugging print statements to show problem behavior. see the messages in the console following the "_WidgetsInTemplateMixin calling parser" message

When chaining promises, immediately signal deferred for non-promise or fulfilled-promise results.

I've committed a fix to Deferred which should resolve this issue. The test cases seem to pass for me, kitsonk could you confirm?

[Kitson Kelly]

Yup, works like a charm. Everything resolves like anticipated. Thanks!!!!
