Error: 0 - Invalid controller: name='', format=''

Hi there,

after installing EventBooking 1.6.9 on Joomla 3.3.6, I created two categories and entered one event for testing the component. I created a menu item with the "Category Calendar Layout" view and stored it with one category selected.
As soon as I select the menu item in the frontend, it throws an error page with the message:

After that, I tried the menu-view "Calendar" which works normal and shows the calendar and the upcoming event.

Further on when I select the "Categories List" view, it first works, showing the two created categories in the frontend. When I selct one of this categories, the same error occurs.

So it seems always to crash, when a certain category gets selected.

Thanks in advance
Ralph

HI Ralph

That's strange. Could you please submit a support ticket sending me super admin account of your site ? I am going to check to see what's wrong and get it sorted for you

Hi Tuan,

Do you have an answer on this? I am getting the same problem, also if I use your standard PayPal gateway.

I remember there was a bug in a module which is using on the Kampmann website and it causes the issue. You can submit a support ticket so that I can check it for you

Tuan

Thanks for the info, which point me to the right place. You are right it has to do something with one of the extensions on that particular page. I had already turned jQuery and Twitter Bootstrap off in your JoomDonation configuration. But still something, probably jQuery, is interfering. Time for the firebug

Hi Nico,
I think it hasn´t anything to do with JS. Its more on the php side. In our case a module wasn't programmed very well. So try to deactivate 3rd party modules & plugins and see if it works then.

@Nico: This is not an JS or jQuery error, so if you go with that direction, it will wait your time.

@Ralph: Do you remember the name of the module which causes the conflict ? If you can post it here, that would be great (I don't remember the name of that module now )

Tuan

Hi,
I don´t remember the module, but it was something homebrew from our university which never made it into the JED, so its very unlikely that Nico has the same module. The problem was that this module grabbed every view to unspecific and then produced this error.
When I´m back at work on monday, I can tell you more.
Here´s what Tuan wrote in our ticket, maybe it helps:

This module "think" that category belongs to Joomla core content component and it calls some wrong code (which only be available when the current component is com_content)
I edited the code abit to get the issue fixed. You can get the file /modules/mod_xxxcontact/mod_xxxcontact.php from the dev site, move it to your main site and It will work well
Maybe you should inform the developer of that module about the bug as well. Tell them that there are many extensions out there have view "category", view "article", so they should check and only run the module when the current component is com_content

The easiest way will be to deactivate all 3rd party module & plugins and if it works then, just switch them on again one after the other to find out which one causes the trouble

Ralph

Thanks Ralph for reminding. The easiest way would be submit a support ticket so that I can check to see what's wrong and get it corrected for you .

Yes I have created a low status ticket, with a way to reproduce it, already.
