Here are the ingredients & the ingredient in question as per paula is the FEVERFEW.

Water, Glycerin, Cocamidopropyl Betaine, Decyl Glucoside, PPG 2 Hydroxyethyl Cocamide, Polysorbate 20, PEG 16 Soy Sterol, Citric Acid, Chrysanthemum Parthenium Extract (Feverfew), Glycine Soja Protein (Soybean), Sodium Cocoyl Amino Acids (Essential Amino Complex), Sarcosine (Essential Amino Complex), Potassium Aspartate (Essential Amino Complex), Magnesium Aspartate (Essential Amino Complex), Phenoxyethanol, Disodium Lauroamphodiacetate, Butylene Glycol, Sodium Coco PG-Dimonium Chloride Phosphate, Sodium Citrate, Tetrasodium EDTA, Methylparaben, Xanthan Gum, Ethylparaben, Butylparaben, Propylparaben, Sodium Hydroxide

Good point Purple.
First, I'm skeptical that a brand like Aveeno produced by a pharmeceutical company like Johnson & Johnson would mass market a product known to cause contact dermatitis.  Their products go through more rigorous pre-market safety testing than probably any other brand out there.  The general advice to avoid it is too extreme.
The Cosmetic Cop's assessment is most likely based only on the inclusion of a single "claims" ingredient not on any actual known cases of dermatitis caused by Aveeno.  The Feverfew is put in the formula at miniscule levels.  Even if their were cases of people being sensitive to it, there is not enough to cause any problems.  The dose matters.
Problem with Reviews
This is the problem with resources like the Beautypedia or the Skin Deep database.  In their zeal to simplify and create something that everyone can use, they over-simplify and give advice that is just wrong.
The rationale goes something like this...Better safe than sorry.
Unfortunately, you are not making yourself safer.  What happens is that people switch to alternatives that could be just as dangerous but have not been as thoroughly tested.  Dose matters!
Something Interesting to Say
The other challenge that Beautypedia or similar sites have is that they can't tell people that EVERYTHING is good (or bad).  They have to say something interesting about products. So, I  can imagine when they see a supposedly 'ultra-gentle" product like Aveeno use a compound known to cause some people problems, they are going to sound the alert.  It's just more interesting than saying Aveeno came out with another gentle product.
We here at the Beauty Brains like and admire the Cosmetic Cop.  But the advice should not be taken as the final word on any product.  No one's general advice can apply to a specific person. 
If you really want to know whether something will work for you, you have to try it yourself.
 

Paula's research obviously isn't perfect, because while Feverfew can be a significant source of irritation, Johnson and Johnson hold a patent on removing the irritating part of Feverfew, so that only the benefits remain.Google it and it comes up on their webpage

I have rosacea and have been using Aveeno's Ultra Calming Face Wash for several years with excellent results.  It's the only cleanser that I have found that doesn't irritate my skin and it really does seem to help with the redness and irritation.  My teenage son, who has mild acne, uses this cleanser with great results.  I agree with Left Brain -- everyone is different and what works on one person may not on another.
