Android Question [SOLVED]Sender for B4XView switch view

[giggetto71]

Hi guys,
I have got a Custom List view made with cards. Each card has several views insiede. By using the following code in the click event of the views I can get the index of the card where the view get clicked (below for example the code executed when I click on a conventional image view inside the card.

Sub imgAlertCardStatus_Click
    
    Dim index As Int = CLV1.GetItemFromView(Sender)

Now, among the view I need to interact with, I have a B4xSwitch view, but using the same code the GetItemFromView crashes.

Sub swEnable_ValueChanged (Value As Boolean)
    
    Dim index As Int = CLV1.GetItemFromView(Sender)

Below, the log I get:

Error occurred on line: 1783 (Main)

Try this:

Dim sw As B4XSwitch = Sender
Dim index As Int = CLV1.GetItemFromView(sw.mBase)
