Thank you, Rakesh. While it is encouraging that it works for you, and I have compared every one of my files with the generic version of them, yet it still doesn't show up for me.
Is there a place in the documentation or anywhere else, where I can find out exactly what goes where in each of the xml files, and where it shows actual examples?
I have googled and googled and tried to find it in the docs, but I haven't found a place that clearly describes everything in detail.
Do I need to learn magento 1 first?
@zuzikaiser have you check your controller file is called or not? first check your controller file action whether its called or not?
You can just reference from Wishlist module, How to render wishlist link in account navigation.
May be you have helpful this core module.
Thank you, Rakesh!
Looking at wishlist, I saw they have the customer_account.xml file in 3 places. Once I did that it worked.
