Hey Guys,

I'm pretty new to the ExtJS framework so be kind

I'm working with a legacy codebase, being ExtJS 3.3.0 and I have written some PHP to load 'data' into my LovCombo

Code:
$testInput = [
    ["\/","\/","false"],
    ["\/Screen Shot 2017-10-09 at 7.08.52 pm-1.png","Screen Shot 2017-10-09 at 7.08.52 pm-1.png","true"],
    ["\/floor",".. floor","false"],
    ["\/floor\/moretesting",".. .. moretesting","false"],
    ["\/floor\/moretesting\/Webserver_requests_graph.jpg",".. .. .. Webserver_requests_graph.jpg","true"]
];
Code:
    var pathStore = new Ext.data.SimpleStore({
        fields:
            [
                { name: 'pathID', type: 'string' },
                { name: 'pathValue', type: 'string' },
                { name: 'leaf', type: 'string'},
            ],
        data: <?php echo $testInput; ?>
    });
As it stands, it puts the 'pathValue' correctly into the combo, but I can only select the first checkbox inside the list, all the others wont allow me to check them.

It's something to do with the json im sending to it, but i cant figure it out.

Any help would be greatly appreciated.

Thanks
