The problem is not assigning the user. Essentially I took the “Editable” example and I created a PHP script to generate the data. In the Editable example the window.getKanbanData() is setting the assignment of the user to the task and the Kanban shows that. When I do that same thing sending it via json remotely, it is not setting it properly.
 
So if I set my javascript as…

async function fetchData() {
    let response = await fetch('/she_test/test2.php');
    console.log(response.status);
    if (response.status === 200) {
        let kbData = await response.json();
        window.Smart('#kanban', class {
            get properties() {
                return {
                    addNewButton: true,
                    collapsible: true,
                    dataSource: kbData.tasks,
                    editable: true,
                    taskActions: true,
                    taskDue: true,
                    taskProgress: true,
                    userList: true,
                    users: kbData.users,
                    columns: [
                        { label: 'To do', dataField: 'toDo' },
                        { label: 'In progress', dataField: 'inProgress' },
                        { label: 'Testing', dataField: 'testing' },
                        { label: 'Done', dataField: 'done', addNewButton: false }
                    ]
                };
            }
        });
        return kbData
    }
}
fetchData();
and it is calling a the following php script...

<?php

echo json_encode($out);
exit();
function getTags($tag=0){
    $tags = array(
        0 => 'initial', 1 => 'data', 2=>'visual', 3=>'property', 4=>'scrolling', 5=>'method');
    return $tags[$tag];
}
It should set the assignment of the tasks be setting the userId in the json data. It is not doing that. I have tried many different ways, just nothing seems to work.

Thanks got it figured out
