B4J Question ABMaterial Problem running on Google Compute Engine

[walterf25]

Hi All, i've had a project running on my work's google compute engine instance, it's been running fine for a few years, recently I made some small changes but suddenly now it crashes and not sure why, when I run the project on my windows machine, it runs fine without an issue, but when I run it in my compute engine instance it crashes.

Here's the crash log I see

java.lang.RuntimeException: java.lang.NullPointerException

This is the part I added recently, basically I added a radiobutton group to this abmodalsheet that displays a QR code

But for some reason having added that part is causing a crash, can anyone think why this would be, it runs fine on my windows machine that's what's puzzling about this.

By the way I am using ABMaterial library 5.15, I have copied all the necessary files to the compute engine instance as well, here's the code where the abmodalsheet is built along with the radiobutton group.

Sub BuildCustomModalSheet() As ABMModalSheet
    Dim myModal As ABMModalSheet
    myModal.Initialize(page, "printqr", True, ABM.MODALSHEET_TYPE_NORMAL, "modalsheet")
    myModal.Content.UseTheme("modalsheet")
    myModal.Footer.UseTheme("snapchat")
    myModal.Size = ABM.MODALSHEET_SIZE_NORMAL
    myModal.MaxHeight = "80%"
    myModal.MaxWidth = "35%"
    myModal.IsDismissible = False
   
    ' create the grid for the content
    '''myModal.Content.AddRows(1,True, "").AddCells12(5,"centre")
    myModal.Content.AddRowsV(1, True, ABM.VISIBILITY_ALL, "centre").AddCellsOS(1, 4, 4, 4, 6, 6, 6, "centre")
    ' ALAIN: Add one row with one cell.  We will add all our Field containers in this cell
    ' this way, we do not have to add rows dynamically
    myModal.Content.AddRows(1,True, "centre").AddCellsOSMPV(1,3,3,3,6,6,6,0,0,0,0,ABM.VISIBILITY_ALL, "centre")
    myModal.Content.AddRows(1,True, "centre").AddCellsOS(1,3,3,3,6,6,6, "centre")
    myModal.Content.addrows(1,True,"").AddCellsOSV(1,3,3,3,3,3,3,ABM.VISIBILITY_ALL,"").AddCellsOSV(1,1,1,1,3,3,3,ABM.VISIBILITY_ALL,"")
    myModal.Content.BuildGrid 'IMPORTANT once you loaded the complete grid AND before you start adding components

    Log("encrypt: " & encrypt($"Type=${mtype}&Model=${model}&SerialNO=${serialno}"$))
    Dim encrypted As String = encrypt($"Type=${mtype}&Model=${model}&SerialNO=${serialno}"$)
    '''Dim equiptmentqr As QRCodeGenerator
    Dim equiptmentqr As QRCodeGenerator2
    Dim murl As String
    Dim su As StringUtils
    murl = encyptedurl
    equiptmentqr.Initialize(page, "equipqr", murl&encrypted, 256)
    myModal.Content.Cell(2, 1).AddComponent(equiptmentqr.ABMComp)
   
    Dim option1 As ABMRadioGroup
    option1.Initialize(page, "labelsize", "radio")
    option1.Title = "Select Label Size"
    option1.AddRadioButtonNoLineBreak("50x50 mm", True)
    option1.AddRadioButton("50x25 mm", True)
    option1.SetActive(1)
   
    myModal.Content.SetBorderex(ABM.COLOR_BLACK, ABM.INTENSITY_DARKEN2, 2, ABM.BORDER_GROOVE, "20px")
   
    myModal.Content.Cell(3,1).AddComponent(option1)
    myModal.Content.Cell(3,1).Refresh
    ' create the buttons for the footer
    Dim msbtn1 As ABMButton
    msbtn1.InitializeFlat(page, "qrprint", "", "", "PRINT", "footerbutton")
    msbtn1.UseFullCellWidth = True
    myModal.Content.Cell(4,1).AddComponent(msbtn1)
    myModal.Content.Cell(4,1).UseTheme("centre")

   
    Dim msbtn2 As ABMButton
    msbtn2.InitializeFlat(page, "qrclose", "", "", "CANCEL", "footerbutton")
    msbtn2.UseFullCellWidth = True
    myModal.Content.Cell(4,2).AddComponent(msbtn2)
    myModal.Content.Cell(4,2).UseTheme("centre")
   
    Return myModal
End Sub

Hope to be able to solve this issue, as I mentioned, i've had this project running for around 3 years and it gets used at work a lot, so it look real bad on me, if I can't get this to work again.

What if you replace the radiobutton with ABMCombo or ABMButton from the menu ?
This way you will check if it is the fault of ABmRadio component
