Hi,

We have requirement of creation of GridLayout(editable) grid with one user or group column having add and remove row features. here is the sample code for the same. but we are facing when clicking the "Add item" link like "Expression evaluation error at function 'append' [line 94]: Could not cast from Dictionary to User or Group. Details: CastInvalid".

 

here ri!users is array of User or Group type. Please do the needful to rectify the casting error.

a!sectionLayout(
          label: "Security Group",
          contents: {
            a!gridLayout(
              label: "Members of New Group:",
              totalCount: count(
                ri!users
              ),
              headerCells: {
                a!gridLayoutHeaderCell(
                  label: "Membership"
                ),
                /* For the "Remove" column */
                a!gridLayoutHeaderCell(
                  label: ""
                )
              },
              rows: a!forEach(
                items: ri!users,
                expression: a!gridRowLayout(
                  contents: {
                    a!pickerFieldUsersAndGroups(
                      required: true,
                      value: ri!users,
                      saveInto: ri!users
                    ),
                    /* For the Removal Column*/
                    a!imageField(
                      label: "delete " & fv!index,
                      images: a!documentImage(
                        document: a!iconIndicator(
                          "REMOVE"
                        ),
                        altText: "Remove User or Group",
                        caption: "Remove ",
                        link: a!dynamicLink(
                          value: fv!index,
                          saveInto: {
                            a!save(
                              ri!users,
                              remove(
                                ri!users,
                                save!value
                              )
                            )
                          }
                        )
                      ),
                      size: "ICON"
                    )
                  },
                  id: fv!index
                )
              ),
              addRowlink: a!dynamicLink(
                label: "Add an Item",
                value: {
                  Membership:""
                },
                saveInto: {
                  a!save(
                    ri!users,
                    append(
                      ri!users,
                      save!value
                    )
                  )
                }
              )
            )
          }
        )

Thanks in advance.

    Can you try the below code?

     

    load(
  local!noOfRows: 0,
  a!sectionLayout(
    label: "Security Group",
    contents: {
      a!gridLayout(
        label: "Members of New Group:",
        totalCount: local!noOfRows,
        headerCells: {
          a!gridLayoutHeaderCell(
            label: "Membership"
          ),
          /* For the "Remove" column */
          a!gridLayoutHeaderCell(
            label: ""
          )
        },
        rows: a!forEach(
          items: if(
            local!noOfRows < 1,
            null,
            enumerate(
              local!noOfRows
            ) + 1
          ),
          expression: a!gridRowLayout(

    ramp,

    Below code should work for both the scenarios

    a!sectionLayout(
  label: "Security Group",
  contents: {
    a!gridLayout(
      label: "Members of New Group:",
      totalCount: count(
        ri!users
      ),
      headerCells: {
        a!gridLayoutHeaderCell(
          label: "Membership"
        ),
        /* For the "Remove" column */
        a!gridLayoutHeaderCell(
          label: ""
        )
      },
      rows: a!forEach(
        items: ri!users,
        expression: a!gridRowLayout(
          contents: {
            a!pickerFieldUsersAndGroups(
              required: true,
              value: fv!item,
              maxSelections:1,
              saveInto: a!save(
                fv!item,
                if(
                  a!isnullorempty(
                    save!value
                  ),
                  null,
                  save!value
                )
              )
            ),
            /* For the Removal Column*/
            a!imageField(
              label: "delete " & fv!index,
              images: a!documentImage(
                document: a!iconIndicator(
                  "REMOVE"
                ),
                altText: "Remove User or Group",
                caption: "Remove ",
                link: a!dynamicLink(
                  value: fv!index,
                  saveInto: {
                    a!save(
                      ri!users,
                      remove(
                        ri!users,
                        save!value
                      )
                    )
                  }
                )
              ),
              size: "ICON"
            )
          },
          id: fv!index
        )
      ),
      addRowlink: a!dynamicLink(
        label: "Add an Item",
        value: null,
        saveInto: {
          a!save(
            ri!users,
            append(
              ri!users,
              ""
            )
          )
        }
      )
    )
  }
)

     

    Also, if you just want to pick the multiple user or group, you can directly use the pickerFieldUsersAndGroups component to select multiple values.
