Advanced Search throws error

[econveyors]

Hello,
When I try to open the Advanced Search box on a specific list, it gives me the error "0 - Call to a member function get() on null". The Network tab in developer tools shows http://mysite.com/media/jui/js/jquery.js as the initiator.

I have tried to disable all elements from being shown in the Advanced Search and it did not make a difference.

Any thoughts on where to look to debug this?

Clearly the jQuery is not finding something in one of the elements, I just can't figure out what it is.

Other lists on this site don't have any issues with Advanced Search.

Edited to add:
I turned on error reporting and noticed these errors on the list.

Notice: Undefined variable: item in /../components/com_fabrik/models/list.php on line 12274

Notice: Trying to get property 'id' of non-object in /../components/com_fabrik/models/list.php on line 12274

Line 12274 is
$context = 'com_'.$package.$menu.$item->id.'list'.$listId;

So, it's looking for the list id?

Also, I do have two databasejoin elements in this list, but their values are showing correctly in the list rows, so not sure if they are the issue or not?

Thanks

This is no error, only a notice.
As far as I can see this line is run if you have "Tabs" enabled in list settings "Layout". Does your list have a "Tab field" selected?

Thank you troester. Yes, this list does have a tab field. I just tested disabling the tab field and the advanced search works and no Notices on the list. I would like to still have the tab field enabled if possible though. Any thoughts on that?

I really don't know if a tabbed list is working with advanced search...

Ok. Thanks for your help! At least now I know where the conflict lies and I can move forward from there.
