error saving a fv!index value in an interface

Hi! I have an editable grid in which the user can add new rows. I want a number for each new row generated (1,2...),  and save the value into my local variable (local!LineasPedido).

I tried to configure it by two different ways but, even though the "value" appears in the grid, it is not saved correctly in my local data

Way1:

Way2:

In the next image you can see the value is generated, but the column "Linea Pedido" does not appear on the right side

My code is the following one:

a!localVariables(
  local!LineasPedido,
  {
    a!sectionLayout(
      label: "Líneas Pedido",
      labelIcon: "list-alt-solid",
      contents: {
        a!gridLayout(
          label: "A continuación, incorpore las líneas de pedido correspondientes y pulse el botón de creación",
          headerCells: {
            a!gridLayoutHeaderCell(label: "Linea Pedido"),
            a!gridLayoutHeaderCell(label: "Pedido"),
            a!gridLayoutHeaderCell(label: "Proveedor"),
            a!gridLayoutHeaderCell(label: "Material"),
            a!gridLayoutHeaderCell(label: "Precio Unitario"),
            a!gridLayoutHeaderCell(label: "Cantidad"),
            a!gridLayoutHeaderCell(label: "Importe Total"),
            a!gridLayoutHeaderCell()
          },
          columnConfigs: {
            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),
            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),
            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),
            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),
            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),

            a!gridLayoutColumnConfig(width: "DISTRIBUTE"),
            a!gridLayoutColumnConfig(width: "ICON")
          },
          rows: a!forEach(
            items: local!LineasPedido,
            expression: a!gridRowLayout(

  • You need to understand that the saveInto parameter on any component works only when you interact with that component, if you try to change the value manually in the textField then you'll see the values getting saved in your local variable. 

    For this you need to save the next row number at the time of adding new row i.e, in addRowLink. I can see that you are appending a recordType with some default values in addRowLink but that thing is giving you null may be because the ri!record is empty, you can instead use below code at line 178.

    'recordType!{495578a9-1b23-4253-8145-6418faabe727}.fields.{71427dbb-12db-4f83-bd99-f625bf9af271}': count(local!LineasPedido)+1
