checkbox group and dynamic data

I get the following error when viewing a form with a checkbox group that takes data from a db read action:

Warning: array_combine() expects parameter 1 to be array, null given in mysite/administrator/components/com_chronoforms5/chronoforms/actions/html/html.php(113) : eval()'d code on line 6 

Line 113 is:

eval('?>'.$form->form['Form']['content']);

I setup the DB read and the checkbox group as usual (in CF v4), I don't understand if I'm doing something wrong.

Thank you

Hi Maxx,

It's a PHP Warning, not an Error, you can hide them by setting Error Reporting to System Default or none in the Site Global Configuration.

The Warning comes from Line 6 of the code that is being evaluated. I'm not sure what is in the ['content'] parameter - perhaps the Form HTML?

Bob, you're right, it's a warning. The problem is I don't get any checkbox in the form. Sorry, I forgot to mention that in my OP.
There are at least 10 records returned by the DB Read (I can see them in the Debugger) but no checkbox.

I see them as:

[tags] => Array
        (
            [0] => Array
                (
                    [title] => ROOT
                    [id] => 1
                )

            [1] => Array
                (
                    [title] => bi1
                    [id] => 2
                )
...

In the checkbox group options I entered tags as Data path, title as text key and id as value key.

Hi maxx,

I'm sorry, I have no idea how Max has handled array values in ChronoForms v5. Please ask him using the Contact Us menu above and link to this thread.
