One xCLV and one PCLV side by side accessing the same Items layout which has a label, named LblText Both access the same list data. This code works on the first xCLV, but crashes obviously on the PCLV for good reasons that escape me:
B4X:
Sub LblText_Click
  Dim Index As Int=clv1.GetItemFromView(Sender) ‘line 71
  Dim p As B4XView=clv1.GetPanel(Index)
  Log(p.GetView(0).text)
End Sub
How can you still click the labels on the PCLV without it crashing. I also tried to use: clv1.AsView.Tag=clv1 and clv3.AsView.Tag=clv3
B4X:
Error occurred on line: 71 (Main)
java.lang.ClassCastException: android.view.ViewRootImpl cannot be cast to android.view.View
at anywheresoftware.b4a.objects.B4XViewWrapper.asViewWrapper(B4XViewWrapper.java:88)
at anywheresoftware.b4a.objects.B4XViewWrapper.getParent(B4XViewWrapper.java:185)

Use the label tag to store the correct list.
It is the same exact list, same item layout with the same label name for both customlistviews. I will probably have to create 2 separate layouts with a label having a different name in each for each customlistview to make this work and consequently have one.Sub LblText1_Click and another Sub LblText2_Click

but the objectreferences in the two CLVs are different even if they are based on the same list of data.
Both are populated at the same time: Here is the code to populate the 2 clvs:
B4X:
For Each s As String In MyList
        Dim Pnl As B4XView = xui.CreatePanel("") 'Create a new B4X View
        Pnl.SetLayoutAnimated(0, 0,0, clv1.AsView.Width, 85dip) 'Set the list positiion and dimensions
        Pnl.LoadLayout("Item")
        LblText.Text = s
        clv1.Add(Pnl, s)
        
        PCLV.AddItem(85dip, xui.Color_White, s)        
    Next
