Updating deprecated $db = JFactory::getDbo(); J4 / F4

[ontarget]

I have a bunch of Calc elements using Ajax Calc on J!4.2.7 and F4BetaB
When i update the deprecated:

$db = JFactory::getDbo();

to

use Joomla\\CMS\\Factory;
use Joomla\\Database\\DatabaseInterface;
$db = Factory::getContainer()->get(DatabaseInterface::class);

The ajax calc stops working.
Is it ok to keep using the old method in Fabrik 4 or is there a better way of referencing the database that allows ajax calc to work? @troester seems to have it working (see post below) but it doesn't work for me, the calc element stays the same when other field values are changed.

As it is only a deprecated warning you can keep the old code.

To fix the ajax calc for code with \\ you can modify plugins/fabrik_element/calc/calc.php line 510
$cal = stripslashes($w->parseMessageForPlaceHolder($calc, $d));
