Third party lib works unless I use --prod

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
   Windows 10
2. Versions. Please run ng --version. If there's nothing outputted, please run
   in a Terminal: node --version and paste the result here:
   angular-cli: 1.0.0-beta.11-webpack.2
   node: 4.4.7
3. The log given by the failure. Normally this include a stack trace and some
   more information.
   Error: Uncaught (in promise): No value accessor for form control with name: 'startDate'
4. Mention any other details that might be useful.
   I'm using a third party lib (ng2-datepicker) which works when I use ng-serve, and also works when i use ng build. But as soon as I build with --prod it stops working and I get this error. Pulling my hair out trying to solve the issue, any ideas?

Thanks.

@tomhackettishida we use ng2-typeahead, works just fine with prod

I had a similar experience, possibly with the same root cause?

I published a service to inject D3 as a service (d3-ng2-service) into Angular 2, while its written in TS to published package built exports two version of the transpiled JS (ES5 target/ES 6 module) and (ES6 target/ES6 module).

When importing the service into an angular-cli (beta 15) project, there is no issue, including with the --prod flag.

I locally experimented with using Rollup to provide a UMD bundle as on of the builts, for other module loaders.

The experience I had was essentially the same, when linking the 'experimental' local package version. While the error message differed in detail, it only created a runtime error with --prod, no problem occurred in dev mode.

This was a bug we had in webpack.2 but was fixed for webpack.3: #1662
