Vue2 does not render at all in prod

[awaigand]

Describe the bug
In Vue2.X nothing gets rendered when you build the project in production. This even goes for the seed project. There are no errors.
It does work when you just do "npm run serve" instead of "build", i.e. in development mode.

To Reproduce

1. Checkout vue2 seed branch/repo
2. npm ci
3. npm run build
4. npx http-server dist or similar.

Expected behavior
The form gets rendered.

Screenshots

There are no errors in the console whatsover, but the form does not render.

Browser (please complete the following information):

• Most recent firefox and chrome (and probably all others).

Used Setup (please complete the following information):

• Framework: Vue2
• RendererSet: Vanilla

Thank you!

Thanks for the report. I can confirm that we can reproduce the issue. We'll take a look soon!

Debugging this is quite difficult as there seems to be a problem with the production build of Vue 2 only, i.e. it works with --mode development. It seems the dispatch renderer is correctly invoked, the layout renderer is triggered and successfully finishes its setup routine. Then something bad happens internally in Vue and the rendering process is stopped with a function rendered as a comment into the DOM. This function is Vue's createElement.

Building @jsonforms/vue2 and @jsonforms/vue2-vanilla as CommonJS modules instead of ESM seems to fix the problem for now. We'll take a look at this again with #1722.

We published the fix as a prerelease (v2.5.2-alpha.0). You can consume it via npm install --save @jsonforms/core@next @jsonforms/vue2@next @jsonforms/vue2-vanilla@next.

Thank you ,
this seems to do the trick and works in our production app as well 👍

Thanks again, especially for the incredibly quick work.

I had the same problem but happily found out that this is now released:
@jsonforms/core@2.5.2, @jsonforms/vue2@2.5.2 and @jsonforms/vue2-vanilla@2.5.2
