Hellow all
Kindly, iam wondering , why this is not working, and how to make it work
Main Activity:

B4X: 
Public Sub GetMainIv(prodId As Int) As ImageView
    Return Page(CurrentPage).MainProduct(prodId).MyImage
End Sub

Public Sub GetMainLv(prodId As Int) As Label
    Return Page(CurrentPage).MainProduct(prodId).MyLable
End Sub

Private Sub GetMainColum(prodId As Int) As Int
    Return Page(CurrentPage).MainProduct(prodId).ProdColumn
End Sub

Public Sub GetMainRow(prodId As Int) As Int
    Return Page(CurrentPage).MainProduct(prodId).ProdRow
End Sub

My Class:

B4X: 
Private Sub AddMainProducts
    Private Column,Row As Int
    Private ImV As ImageView:ImV.Initialize("ImV")
    Private Lv As Label:Lv.Initialize
    For i=0 To MainProductList.Size-1
    ImV=CallSub2(ParentObject,"GetMainIv",MainProductList.Get(i))
    Lv=CallSub2(ParentObject,"GetMainLv",MainProductList.Get(i))
    Column=CallSub2(ParentObject,"GetMainColum",MainProductList.Get(i))
    Row=CallSub2(ParentObject,"GetMainRow",MainProductList.Get(i))
    ScrlPage.Panel.AddView (ImV,Column,Row ,33%x,33%x)
    ScrlPage.Panel.AddView (Lv,Column,Row+33%x,33%x ,22%x)
    Next
End Sub

by checking with other user with newer version of B4A he says that the program deal with the
MainProduct(prodId) as array and it shows only its length, while i define it as object.... and it show me all its properties and methods!!!

Actually The Error Very Clear. java.lang.NumberFormatException: Invalid double: "null"
Just Have To Make Sure Don't Pass Null Value
Try Debug More Deeper...
