Categories.

[Kepa]

Hello again:

I'm getting an "error 500" message everytime I try to display the content (list of books) of a single category that I've created as a proof link at the main menu. 
Firstly I wondered it could be a kind of interference between the categories defined through the Category Manager of Joomla! and the categories defined through the Alexandria Book Library component, because in the beginning I did actually define the same categories both ways. So, just in case, I completely deleted all the categories, even from the bin, and restarted from the beginning, this time defining the categories only through com_abook. And then I introduced again the book details.
Finally I went to the Main Menu Item Manager and created again a proof link for displaying the contents of a single category through the Alexandria Book Library component. But I keep getting the same unexpected "error 500" with abookView.
In the other hand, there is no problem at all with the link that displays the list of all categories; again, the links  from this page to each category also yield the same "error 500" anyway.
I have checked the correctedness of the link syntax of the single categories, that reads, for example:

http://localhost/joomla15/index.php?option=com_abook&view=category&id=1&Itemid=17

in which the category identity number (id=1) and the menu item identity number (Itemid=17) do perfectly agree. So, despite the link is calling the right single category, Joomla! is unable to display it...

I'm using Joomla 1.5.22 + Xampp 1.7.4 + Windows XP SP3.

Any suggestion? Thank you very much in advance.

Hi there!

I have just tried the most immediate and plainest of the solutions... and it's worked!

That is, I have installed Joomla! again from zero, installed the a_book component as well, and then enter all the sample data again through a_book component in this order: locations, libraries, editors, authors, categories and books. I have not defined any category nor section at all by means of the Category Manager or the Section Manager.

Through the Alexandria Book Library utility within the Menu Item Manager, I have defined on trial the next menu item types: a link for a single author, a link for a single book, a link for a single category and a link for all categories. I have also defined two single categories under the all categories item as a parent.

As I said before, all works just so fine.

Let's see now how the different modules work.

Hello kepa,
the abook category items are in #_abcategories table and the joomla category items are in #_categories table. You can't create a category into joomla categories manager then use it on abook. The steps that you used in the second post are correct.

Bye bye
