B4J Question [BANanoVuetifyAD3] Error on VComboBox

I have inserted a VComboBox that contains 5 items and each item has its own numeric value
B4X: 
VComboBox1.AddItem(1,"One")
VComboBox1.AddItem(2,"two")
VComboBox1.AddItem(3,"three")
VComboBox1.AddItem(4,"four")
VComboBox1.AddItem(5,"five")


When I select an item, correctly in the Change event it returns me the value.
But the item does not appear in the view but the value which is an index while the selected item should appear.


Why does it happen, is it a bug?


I have attached an example that reproduces the error

Hi, thanks for the report. I've just confirmed if the kitchen sink examples are working...

Will investigate your code and if its a bug, will be fixed.

In the kitchen it works because both the Text and the value match with the same string.

But if you put an entry in the text and an index in the value, the problem arises.

Eureka!



Updated your code to be in line with the kitchen sink examples. You accidentally left out .Clear and .Refresh.

B4X: 
VComboBox1.Clear(page)
    VComboBox1.AddItem(1,"One")
    VComboBox1.AddItem(2,"two")
    VComboBox1.AddItem(3,"three")
    VComboBox1.AddItem(4,"four")
    VComboBox1.AddItem(5,"five")
    VComboBox1.Refresh(page)

All the best.

PS: I will include your example in the kitchen sink, just for more examples to be available. Thx.

I think I have explained myself badly.

The operation I see in your image is what I already get with my example. But this is not the normal behavior.

When I select ONE on the Combo text bar you find "1" but I should find ONE

Just to add, a VCombo has an editable feature, meaning that you can add items to it by typing content on the combo and pressing enter.
Perhaps they did it this way because there is no way to determine what you are entering is a value / text.

If your users will not be adding any item to your combo, use other alternatives or use the same text for values.
