Scrollbar not available inside Scrollview

Under certain unclear conditions QML marks a scrollbar inside a scrollview as a non-existing object.

I have a condition similar to following:

 

Rectangle{

...

ColumnLayout{

...

Flickable{

...

 

ScrollView{

....

 

ScrollBar.vertical: ScrollBar

{ x: 710 width: 20 height: parent.height policy: ScrollBar.AsNeeded interactive: true }

ColumnLayout

{   }

 

}

}

}

}

 

If I add the specifications for the scrollbar, the latter is marked as a non-existing object and therefore the code cannot be executed.

 

NB:

1. The same error occurs by just replacing the entire scrollbar specifications with a simple line like ScrollBar.vertical.policy: ScrollBar.AlwaysOn.

1. When the scrollbar is not explicitly added it either way appears.

1. In an almost identical situation the scrollbar specifications can be successfully added.

 

Should further information be needed please feel free to contact me.
