Bug? Sender: Object should first be initialized (ImageView).

[guenneguez_t]

Hi,

In a fonction I use : Sender
In Debug mode every thing is fine.
When I compile in Release mode, I have the following error :
java.lang.RuntimeException: Object should first be initialized (ImageView).
My sub function is :

Sub ImageViewSerie_Click
    Dim Trigger As ImageView
    Dim Serie As String
    Debug("Sub ImageViewSerie_Click")
    Debug("Sender.tag : " & Sender)
    Trigger = Sender
    Serie = Trigger.Tag

In the log, I have :

22:44:24:976 Main Sub ImageViewSerie_Click
22:44:24:980 Main Sender.tag : null
main_imageviewserie_click (java line: 4692)
java.lang.RuntimeException: Object should first be initialized (ImageView).

I have got the problem with all usage of "Sender".
I try with Button, and have the same problem.

It seem like Sender objet wasn't defined...

Thanks

The order of your statements is wonky. I assume ImageViewSerie is an ImageView with the Tag property set

Sub ImageViewSerie_Click
    Dim Trigger As ImageView = Sender
    Dim Serie As String = Trigger.Tag
    Debug("Sub ImageViewSerie_Click")
    Debug("Trigger.tag : " & Serie)

The order looks correct. The problem is probably in how the event is raised.
Please upload a small project with the relevant code.

Thanks for reply.
I test as explain by William Lancee and it work fine.
I juste replace :

Dim Trigger As ImageView
Trigger = Sender

By

Dim Trigger As ImageView = Sender

Before every think work good but an update (I don't know where) break apps

Best regards
Thomas

Yes, that changes everything. My apologies for saying it was the order. The two fragments of code in post #4 are the same.
Assuming it was an App update, you need to find out what the update changed to break things.
Create a minimal App that works and add the changes that were made - a little at a time.
