为什么Symfony寻找“addWooklyExercise（）”而不是“addWeeklyExercise（）”

I changed, by client requirement, an entity textfield (weekly_exercise) to a 1:n relation. Everything works normally so far, but when trying to save the form Symfony looks out for a "changed" method name.

That's the error message I get

Neither the property "weekly_exercise" nor one of the methods "addWooklyExercise()"/"removeWooklyExercise()", "setWeeklyExercise()", "weeklyExercise()", "__set()" or "__call()" exist and have public access in class "XXX\CourseBundle\Entity\Course".

Of course "addWooklyExercise()"/"removeWooklyExercise()" don't exist. I could put them in and proxy to the real methods, but that would only be an ugly hack.

I've been looking through all my files and couldn't find a anything that could be responsible for this issue.

I'm on Symfony 2.5.7 as my client doesn't allow me to update!!

EDIT:

For some reason the method

public function addWooklyExercise(\BDA\CourseBundle\Entity\CourseWeeklyExercise $weeklyExercise)
{

    $this->__initializer__ && $this->__initializer__->__invoke($this, 'addWooklyExercise', array($weeklyExercise));

    return parent::addWooklyExercise($weeklyExercise);
}

is being added in the cache proxy. But there is also the correctly spelled method, before the misspelled one.

Follow the naming convention like when you add the property for oneToMany then it's plural and for add or remove method change it to singular.

protected $tags;

public function addTag(Tag $tag)
{
    //...
}

public function removeTag(Tag $tag)
{
    // ...
}

That looks like you have a typo somewhere, probably your Entity, your Form-Type or when outputting a form in a template. Try doing a search over the whole src/ directory for wookly and you will probably find it.
