B4J Question Changes to Layout In Designer Results in revised layout throwing error

[rgarnett1955]

Hi,

I am loading a layout as part of a custom view.

'======================================================================================
Private Sub CreateCurveListItem(cv As curveSetupRec_t) As Pane
    Dim p As AnchorPane
    p.Initialize("")
    'p.LoadLayout("cvCurveSetups - Copy.bjl") ' <===='  Error here
    p.LoadLayout("cvCurveSetups.bjl") ' <===='  This work fine
    p.SetSize(1000, 64)
   
   
    setLineWidthSpinner(spinLineWidth)

    lblCurveID.Text             = cv.curveID
    lblCurveID.Tag                 = "curveID"
    lblCurveNo.Text             = cv.curveNo
    lblCurveNo.Tag                 = "curveNo"
    txtYMax.Text                 = cv.maxVal
    txtYMax.Tag                 = "maxVal"
    txtYMin.text                 = cv.minVal
    txtYMin.Tag                 = "minVal"
    cPickCurve.SelectedColor     = fx.Colors.From32Bit(cv.curveColor)
    cPickCurve.Tag                 = "curveColor"
    txtCurveName.Text             = cv.curveName
    txtCurveName.Tag             = "curveName"
    txtYUnits.text                 = cv.curveUnits
    txtYUnits.Tag                 = "curveUnits"
    spinLineWidth.SelectedIndex    = spinLineWidthMap.Get(cv.curveLineWidth)
    spinLineWidth.Tag            = "curveLineWidth"
    cbInitialDisplay.Checked     = cv.initialDisplay
    cbInitialDisplay.Tag         = "initialDisplay"
    cbPlotCurve.Checked            = cv.initialDisplay
    cbPlotCurve.Tag                = "cbPlotCurve"
    cbYAnnotations.Checked         = cv.yAxisAnotations
    cbYAnnotations.Tag             = "yAxisAnotations"

'    Log("Curve No: " & cv.curveNo  & "  cbPlotCurve.Checked  " &  cbPlotCurve.Checked &  "  cbYAnnotations: "  & cbYAnnotations.Checked)
    Return p
End Sub

It was working fine until I made rearrangements of the views within the layout. After I did this I received the following error:

I have attached the two layout files in a zip.

This one works:

This one crashes:

Can some one have a look at this problem please? I can't provide the entire project as it is very large and complex.

Additional:

I made a small test project which loads the two layouts into separate panes. The error still occurs in this environment. I am using B4J 8.5 with W:\MyProgramFiles_W\Java_11_0_1\bin\javac.exe.

Moved to the questions forum.

Tip: no need to write the layout file extension. This way you can write cross platform code.

When you see an error related to json and the designer you know that there is a broken menu somewhere.

In this case it is here:

The context menu should hold a json string: https://www.b4x.com/android/forum/threads/designer-menu-items.56602/#content
