Unable to subload data in multicolumn combo from JSON source

Suite and Optimus Suite 5

Hello,

I’m trying to populate multicolumn combo from json source. Can you help me please to understand, what am I doing wrong? Is the way to sub-load data from json not the same as with xml? I actually need same behaviour as in this sample shown, but from a JSON source:
[url]http://dhtmlx.com/docs/products/dhtmlxCombo/samples/08_advanced/08_multicolumn_subload.html[/url]

The generated JSON is adapted to XML structure from sample above:

{
   "options":[
      {
         "value":9687500,
         "text":{
            "word":"oftest",
            "number":973
         }
      },
      {
         "value":8944702,
         "text":{
            "word":"gastrointestinal",
            "number":689
         }
      }
   ]
}

And like in example shown, I just use this line of code to populate data:

comboJSON.enableFilteringMode(true, "random_words.php?type=JSON", true, false);

Attaching adapted example (PHP is required). While XML loading works fine, JSON loading produces an error:
TypeError: Cannot read property ‘documentElement’ of nulll

Thank you!

p.s. we’re using / testing dhtmlxSuite 5.0.2 pro

Unfortunately, dynamic loading works with XML only for now.
We will try to make this functionality JSON compatible in the next update
