attribute view [ ] is not a table

Error message

attribute view [%s] is not a table

What it means

GetAttributeViewPasteRows resolves the attribute view's current viewable and asserts it is a *av.Table before computing paste rows. If the view's layout is not a table (e.g. kanban or gallery), the assertion fails and this error is returned — paste-row extraction is only implemented for table layouts.

Solutions

1. Switch the target view's layout to Table before calling GetAttributeViewPasteRows
2. Pass the viewID of a table view instead of relying on the default/active view
3. Handle the error in the caller and fall back to a table view or reject the paste operation

Example fix

// before
rows, _, err := model.GetAttributeViewPasteRows(avID, viewID, groupID, startID, count)
// after
if layout := getViewLayout(avID, viewID); layout != av.LayoutTypeTable {
    return fmt.Errorf("paste requires a table view, got %s", layout)
}
rows, _, err := model.GetAttributeViewPasteRows(avID, viewID, groupID, startID, count)

const view = await api.getAttributeView(avID, viewID)
if (view.type !== "Table") { throw new Error(`view ${viewID} is not a table`) }

function isTableView(v) { return v != null && v.type === "Table" }

rows, _, err := model.GetAttributeViewPasteRows(avID, viewID, groupID, startID, n)
if err != nil && strings.Contains(err.Error(), "is not a table") {
    return ErrPasteRequiresTableView
}

When it happens

Trigger: Calling GetAttributeViewPasteRows for an avID whose active view (or the view resolved for the given viewID) has layout type other than table; pasting rows into a non-table database view.

Common situations: Clipboard paste handler invoked while a kanban/gallery view is selected; switching a view's layout to kanban then programmatically requesting paste rows; stale viewID pointing at a non-table view.

Understand the failure class

Background: "is not a compatible type" / "cannot merge" errors: when a value's type doesn't match what the library requires — this error's family across 65 libraries.
