Problem/Motivation

While developing config_readonly, effulgentsia and I discovered that the views preview form is a config entity form. Is there a reason why it has to be implemented that way and coupled to ConfigEntityInterface?

This line from config_readonly.module returns TRUE and triggers the config_readonly message:

$form_state['controller']->getEntity() instanceof ConfigEntityInterface;

Proposed resolution

Decouple views preview from config, though I must admit I don't have a concrete proposal at the moment.

Remaining tasks

User interface changes

TBD

API changes

TBD

$form_state['controller']->getEntity() instanceof ConfigEntityInterface;
If I read that line right, it gets the entity from the form and checks if this is a config entity. The Preview displays how a View is rendered, and since a View is a config entity, I'm not sure what is bugged here.

But if this is still an issue, please feel free to reopen this.

I think the point is that while a View is a config entity, submitting the preview form doesn't make any changes to config. config_readonly uses this mechanism to detect and show a message on forms that might change config - it incorrectly shows a message here because it thinks the form is used to manage a config entity, but that's not actually true.

The way to rearchitect this would be to change the parent class of ViewPreviewForm so it doesn't extend from ViewFormBase (which then inherits from EntityForm), and perhaps move some parts of ViewFormBase into a trait so they can be reused as required.

However I'm not sure this is strictly a bug so reclassifying this as a task for now.
