Version

3.0.1

Reproduction link

https://jsfiddle.net/Terrijoo/pntLxf20/

Steps to reproduce

  1. open console
  2. click /home
  3. click Info
  4. click /foo
  5. look into console 6492

What is expected?

The props still being "there" and no warning about the missing required prop.

What is actually happening?

The props are apparently removed/emptied and vue throws a warning.

It's a combination of several circumstances:

  1. router-view needs to be wrapped by keep-alive
  2. props needs to be required on the component
  3. prop needs to be on the children, it does work on the parent:
  • click /home
  • click /foo
  • no error/warning
