EntityRouteEnhancer and HtmlEntityFormController should document requirements for the _entity_form property

Aditi Saraf → made their first commit to this issue’s fork.

Should we add a runtime assertion so anyone who makes this mistake gets a better error message?

i will work on this ..

@Joachim i am not able to reproduce this issue .

I can still see the call to setModuleHandler in getFormObject(), which AFAICT isn't in FormBase.

@joachim, I am trying to understand the issue. Would you like to provide more details about it ? What are you trying to achieve ?

If you define a route that uses an entity form, you use '_entity_form' in the route definition, and set a form class name as a value.

If your form class inherits the standard form class base, it crashes.

The docs for _entity_form in entity.api.php should say that you need to use a specific base class.
