QML ScrollView binding loop for "contentHeight"

prex

Binding loops with scroll views seem to be a popular topic. However, I couldn't solve this issue with the existing posts I found. I'm getting the error:

QML ScrollView: Binding loop detected for property "contentHeight"

when I'm doing the following in my Qml file:

ScrollView {
           id: scrollView
           width: 1480
           height: 197
           font.pointSize: 14
           clip: true
           ScrollBar.horizontal.policy: ScrollBar.AlwaysOff

           ListView {
               id: logView
               x: 20
               y: 672
               model: qros.rosLog
               delegate: logDelegate
               spacing: 5
           }
       }

       Component {
           id: logDelegate

           RowLayout {
               Text {
                   Layout.maximumWidth: 1480
                   color: "#FFFFFF"
                   font.family: "Arial"
                   font.pointSize: 8
                   wrapMode: Text.WordWrap
                   text: modelData
               }
           }
       }

I don't see where this comes from since this looks like the example.

@prex Can you accomplish the same thing without a scrollview? I have found I can do the same with the version 2 of ListViews without scrollviews. YMMV.

@prex
Give your Listview a width/height and the binding loop should go away.

I assume, without hight/width set, it scales itself to its content and that trickers a contentHeight change of the scrollView

@J-Hilk Unfortunately, this didn't solve it. The GUI works fine until I start scrolling manually in the ScrollView, while new elements are added to the ListView.

@fcarney Easy as that. This works perfectly fine with just a ListView. I added a ScrollBar to it and I have the same without any binding loops. Thanks!
