TOPIC: Select detail article link from weblink or banner category?

Hi all,

if i create a new event or edit a existing event either from backend and also from frontend event management i have the following problem:

If I select the category for the detail article link for the event, not only the categorys for my articles are shown, but also the categorys for my
weblinks, banners, contacts, newsfeeds and so on.

Is this expected? I don't see any sense in selecting a detail article from a category other than from my content categorys.

I would like to hear, if anyone else has experienced this and has suggestions. Hope, that my database is not corrupt...

(Joomla 2.5.8; DTRegister 2.8.3; PHP 5.4.10 on my site)

Regards,
Stefan

Oh!
I'm replying to my own post. This is weird.
But I found a solution for my problem...

In add_tab.general.php there's a query for the database:

$query = "Select c.* from #__categories c where published <> 0 and parent_id > 0 ".$con." order by lft asc ";

This query will return all categorys from the ***** _categorys table of the database - which are published and parent_id > 0.

Better would be perhaps:

$query = "Select c.* from #__categories c where published <> 0 and extension = 'com_content' and parent_id > 0 ".$con." order by lft asc ";

Seems to work for me - but I'm not a SQL expert and I'm unsure about the side effects my changes will have, so i would like to hear what dth_development says to this change.

Regards,
Stefan
