I’m trying to implement a listview and used your LevelSelectionScene.qml as a reference, but I can’t get it working properly.Everything works, except my model which points to a function which is a getValue call to my Storage. My storage currently contains

one JSON.stringified object which I want to set to the model.

 

FlickList.qml
Flickable {
id: flickable
property alias model: repeater.model

Repeater {
id: repeater
delegate: testDelegate
model: loadListModel()
onModelChanged: {
console.debug(“something changes”)
}
}

Component {
id: testDelegate()
Rectangle {
width: 100; height: 200
color: “black”
border.color: “black”
Text {
text: repeater.model[0].name // returns  [undefined]
font.family: defaultFont.name
color: “white”
}
}
}

function loadListModel() {
console.log(“loading “)
return [parapendium.getValue(“test”)] // returns my object inside an array
}
}

In some other .qml where I use the FlickList.qml component from above I call explicit:

flickList.loadListModel() and my FlickList creates one object, but the properties inside the delegate can’t be resolved.

Why has it to be that complicated? D:

Forget what I said, I found the problem:

Taken from storage.js line 122

 var rs = tx.executeSql('INSERT OR REPLACE INTO settings VALUES (?,?);', [key,JSON.stringify(value)]);

There is JSON.stringify called again on the value which I already JSON.stringified. Passing a non-stringified object solves the problem.

 

I think that should be mentioned in the documentation somewhere.
