Can I only use one DB in Joomla 3.2

I've got a menu with two links, one: Projects that links to catalog 1 and two: Stages, links to catalog 2.
When I enable Joomla cache I can only use the catalog that I select first, the menu link of the other catalog loads the first catalog.
After disabling Joomla cache they both work.

What's remarkable is that the url doesn't contain information about which catalog to use?
example: index.php?option=com_joodb&Itemid=493&view=catalog&lang=en

I would like to be able to use caching, or is this a useless feature? ;-)

Thanks a lot for your support!

You are right. There is an issue with the caching since 3.0
Will be fixed in one of the next versions.

You should disable caching until.

Joomla caching with external components is a mess!

I agree.
Do you think that the JOTcache extension is a better method for caching?

Have a nice day :-)

I don't know JOTcache and I wouldn't use it because the Joomla cache isn't bad at all.

The best way is probably a cache completely independent and optimizations like APC.

Caches are complicate and they always have problems such things like ajax calls!

JooDB will work with the new Joomla3 cache next version!
