Hannes. I'm unable to reproduce your SEF URL problem. Here are the steps I took in an effort to recreate your problem using Joomla Version 1.5.12:
I first enabled SEF URLs per this article.
- Admin > Site > Global Configuration >
Site > SEO Settings > Yes to the
three options.
I then created test content without adding it to a menu:
- Admin > Content > Section Manager > New > "Test Section"
- Admin > Content > Category Manager > New > "Test Category"
- Admin > Content > Article Manager > New > "Test Article" and assigned it to "Test Section / Test Category"
Now I have a Joomla article that is not assigned to a Menu.
I then went to another article in my site and created a link to my Article entitled "Test Article."
- Admin > Content > Article Manager > Edit > "Source Article"
- Highlight/select a word > Insert/Edit Link > Link Browser > Content (NOT Menu) > Test Section > Test Category > Test Article > Insert
Note that I was able to link to this article by selecting it as Content. Had I assigned it to a menu, that also would have been an option, but it is not a requirement.
Next I go to the front-end to determine if the "Test Article" has a SEF URL or not. In my case, even though "Test Article" was not assigned to a Joomla Menu, it did have a SEF URL when I followed this method.
My SEF URL looked something like this (using example.com as a "fake" domain):
- somedomain/test-section/99-test-category/217-test-article.html
I started building a new Joomla site in May 2009 using 1.5 and so far have not found a need for the sh404SEF extension, although I have observed it has positive reviews.
