Look at /Controllers/ProductController.cs and find the ProductReviewForm() method.

Notice at the top, the code (sort of) checks to make sure a valid product object is decided before continuing with the actual work to be done inside the if (product != null)

But the view model is built outside the if (product != null) check, so a null product passed to the method throws an exception trying to grab the product url.

Also I'm pretty sure if product reviews are disabled in the store settings, a null product object will also happen by the time the code tries to build the view model.

Hi Joe,

I reported an issue with Product Reviews about a month ago. I'll have the team follow up and see if it's the same thing you are seeing.

REF. AC9-1912
Thanks for your support!

Joe,
You are right about the null exception if product is null BUT I am wondering how a null product object can be passed to the ProductReviewForm action unless you explicitly pass ProductId = 0 or use the reviews widget on any other page except product page. In the normal scenario, the Reviews form will always be in the product context because it is being used on the product page.

The ProductReviewForm action can never be called if the product reviews are disabled. This action only called when you click the WRITE A REVIEW button.

Any ways, we will improve the code to be null safe as you suggested. Thank you!
