Datable external configuration file problem

If I use an external configuration file (JSON) to organize and fill a datatable, this will not work well.
If I call the json file in different ways, it just show me the database structure (columns) from configuration but not the data from the data part.
I tried with:

                webix.ajax().get("loadmainview.php?view=1", function(text, data, XmlHttpRequest){
                    $$("mainViewAfterLoad").clearAll();
                    $$("mainViewAfterLoad").parse(text);
                    //$$("contextDetails").show();
                });

and also

                $$("mainViewAfterLoad").clearAll();
                $$("mainViewAfterLoad").load("loadmainview.php?view=1");

Both fail same. Structure is there but no data.

BTW: Because the data will get visible after I open or close the Java-Script Console I think there is a bug in webix.

can you share your data structure?

{
“config”:{
“columns”:[
{
“id”:“context”,
“header”:“Context”,
“adjust”:“data”
},
{
“id”:“cs”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“de”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“en”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“es”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“fr”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“hu”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“it”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“nl”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“pl”,
“header”:“Sprache”,
“width”:200
},
{
“id”:“sk”,
“header”:“Sprache”,
“width”:200
}
],
“autowidth”:“true”
},
“data”:[
{
“id”:“1”,
“context”:“Aufliegend”,
“cs”:“Průběžně”,
“de”:“durchgehend”,
“en”:“continuous”,
“es”:“continuo”,
“fr”:“Filante”,
“hu”:“egységes”,
“it”:“continuo”,
“nl”:“doorlopend”,
“pl”:“nakładany”,
“sk”:“priebežný”
},
{
“id”:“2”,
“context”:“Aufschlagend”,
“cs”:“Standardní korpus 2”,
“de”:“Standardkorpus 2”,
“en”:“Standard cabinet 2”,
“es”:“Cuerpo de mueble estándar 2”,
“fr”:“Corps de meuble standard 2”,
“hu”:“Standard korpusz 2”,
“it”:“Corpo mobile standard 2”,
“nl”:“Standaardcorpus 2”,
“pl”:“Korpus standardowy 2”,
“sk”:“Štandardný korpus 2”
}
]
}

Just with 2 lines of data. But the same behaviour. Content only available after like open/closed Java Script Console.

please check other parts of your code.
or if possible share a snippet.
AFAICS everything works as expected.

You are right. There was a design issue with scrollview. It seems to be important to define rows in the body. After adding the rows array the data will be shown.
Thank you for your help, it was the right way to find the problem.
