In "How to Unit Test your Forms", where does `fromArray()` come from?

[Kwadz]

In this example we can notice the fromArray() method to hydrate $object. However this method exists only for a Propel entity.

If I am not wrong we should mention that this method has to be manually created for Doctrine entities if the user want to test forms like this.

What do you think?

Thanks for reporting this error. I'm trying to fix this in #8971.
