Value Help in Launchpad have no cells and filter

Hello togehter,

I built an app in the WebIDE and there the value help from an input works. But in the launchpad it doesn't work.

There are no cells.

Launchpad:

The text in the table on english: "There are no visible columns in the table right now. Please select the columns you need in the table settings"

What could be the reason for this? This is a own SAPUI5 App and by implement the value help, I used this sample as a guide. For the columns I used a json-File too. Could it have something to do with that? Does the path in the launchpad need to be different?

this.oColModelA = new sap.ui.model.json.JSONModel("model/columnsModelAnla.json");

regards

Tim
