Value Help in Launchpad have no cells and filter

[Former Member]

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

check the console to see if you were able to load the json file.
if not, try this.

var sPath=sap.ui.require.toUrl("model/columnsModelAnla.json")
var oModel =new JSONModel(sPath);

Hey Jun,

thank for comment. According to the network, it doesn't even load.

And your tip doesn't work.

This is my code now:

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

var aColsB = this.oColModelA.getData().cols;

debug your code, is your code executed?

Yes my code is execute but the oColModelA is empty.

Instead of using the json-file I did it that way:

var cols = [{
				label: "Anlagennummer",
				template: "ANLN1"
			}, {
				label: "Unternummer",
				template: "ANLN2"
			}, {
				label: "Buchungskreis",
				template: "BUKRS"
			}, {
				label: "Bezeichnung",
				template: "TXT50"
			}, {
				label: "Bezeichnung",
				template: "TXA50"
			}];

this.oColModelA = new sap.ui.model.json.JSONModel();
this.oColModelA.setData({
     cols: cols
});

var oColsB = this.oColModelA.getData().cols;

And this is working!

where is your ui/view code?

"There are no visible columns in the table right now" this is driven by annotation.

this should have nothing to do with your json data.

when you debug what is the value for sPath ?

you may have to adjust "model/columnsModelAnla.json", it depends on your folder structure.
