Android Question B4XPlusMinus ClassCastException

[madru]

Morning,

how can I get the sending B4XPlusMinus (get his value) from a Pane (Panel) in a CustomListView?

clv1.Add(addItemtoListview(PossibleFailure, clv1.AsView.Width, 40dip), "test")

Sub addItemtoListview(flist As List,  Width As Int, Height As Int) As Pane
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, Width, Height)
    p.LoadLayout("CellItem")
 
    pmOne.SetNumericRange(0, 100, 1)
    pmTwo.SetNumericRange(0, 100, 1)
    pmThr.SetNumericRange(0, 100, 1)

    cbBox.Items.AddAll(flist)

    Return p
End Sub

Sub pmOne_ValueChanged (Value As Object)
    Dim index As Int = clv1.GetItemFromView(Sender)
    Dim p As B4XView = clv1.GetPanel(index)

    Dim pmOne As B4XView = p.GetView(0)'0 as example'
    Dim pmTwo As B4XView = p.GetView(1)'1 as example'
    Dim pmThr As B4XView = p.GetView(2)'2 as example'
End Sub

this does work for textfields etc but not for this

java.lang.ClassCastException: class b4j.example.b4xplusminus cannot be cast to class javafx.scene.Node (b4j.example.b4xplusminus is in unnamed module of loader 'app'; javafx.scene.Node is in module javafx.graphics of loader 'app')

THX

[madru]

this does work....

Sub pmOne_ValueChanged (Value As Object)

'Log(Sender)
    Dim x As B4XPlusMinus=Sender
'   Dim x1 As B4XPlusMinus = x
    Log(x.SelectedValue)
End Sub

but i don't get the other components (to do some math) on the panel now

 

[madru]

this does work now, is this the correct approach ?

    clv1.Add(addItemtoListview(PossibleFalure, clv1.AsView.Width, 40dip,c), "aa")
    c=c+1

Sub pmOne_ValueChanged (Value As Object)

        Dim x As B4XPlusMinus=Sender
        Dim p As B4XView = clv1.GetPanel(x.Tag)
        Dim x2,x3 As B4XPlusMinus
        x2 =p.GetView(1).Tag
        x3 =p.GetView(2).Tag

        Log(x2.SelectedValue)
        Log(x3.SelectedValue)

        x2.SelectedValue=10-x3.SelectedValue ' do something with the three values

End Sub

Sub addItemtoListview(flist As List,  Width As Int, Height As Int,count As Int) As Panel
         Dim p As B4XView = xui.CreatePanel("")
         p.SetLayoutAnimated(0, 0, 0, Width, Height)
         p.LoadLayout("CellItem")
         p.Tag=count
        
         pmOne.SetNumericRange(0, 100, 1)
         pmOne.Tag=p.Tag
         pmTwo.SetNumericRange(0, 100, 1)
         pmTwo.Tag=p.Tag
         pmThr.SetNumericRange(0, 100, 1)
         pmThr.Tag=p.Tag
   
         cbBox.Items.AddAll(flist)

         Return p
End Sub
