Author has superficial knowledge

I have found a few examples of fundamental holes in the author's knowledge that make me concerned about how much I should rely on this book.

The mistake that motivated me to write my first ever Amazon review was in "Recipe 6.2 Relaying Actions". The author has a box of text labeled "Avoid Chaining Actions" where he cautions the reader not to forward from one action to another. I quote:

"Beware this temptation! If you follow this path, you've essentially substituted Java method calls with HTTP requests. It doesn't take a rocket scientist to know that an HTTP request is much slower than a Java method call."

If the author had a solid understanding of the subject matter, he would know that forwarding from one action to another does not involve an HTTP request. If the book had been peer reviewed, obvious mistakes like that would have been corrected.

Since there could not have been a peer review, I am depending on the author's expertise when I use one of the recipes. I'm not sure that's such a good idea now.
