Flow: Grid broken in 14.0.0.b1?

[stefanuebe]

I tried to migrate the Simple App (Vaadin Starters) to V14 beta1. The application starts up as normal (beside the bower / npm warning).

After logging in, the UI gets redirected to the default page. There the grid is missing and a bunch of error messages pop up.

Some console error examples (Chrome)

I want to chime in and say that I am encountering this issue as well and posted about it on the Fourm.

I had the same problem with 14.beta1, and I found a workaround in the pom.xml example

@ericmartinezr works as a temporary solution, thanks for the idea :)
