attribute view [%s] visible view [%s] not found

Error message

attribute view [%s] visible view [%s] not found

What it means

If the template node sets the visible-view-ids IAL (av.NodeAttrVisibleViewIDs), each listed view ID must exist in the attribute view. This error reports the first visible-view ID that no longer resolves — typically a view deleted after the template captured its visible-view list.

Solutions

  1. Re-save the template from a document whose database still has all listed visible views
  2. Edit the template custom-av-visible-view-ids attribute to list only existing view IDs
  3. Remove the custom-av-visible-view-ids attribute so default view behavior applies

Example fix

// before (database block IAL in template)
{: custom-av-visible-view-ids='20240101-a,20240102-deleted'}
// after
{: custom-av-visible-view-ids='20240101-a'}
Defensive patterns

Strategy: validation

Validate before calling

for _, id := range strings.Split(node.IALAttr('custom-av-visible-view-ids'), ',') {
    if id = strings.TrimSpace(id); id != '' && attrView.GetView(id) == nil {
        // prune the stale ID before validation
    }
}

Type guard

func allVisibleViewsExist(attrView *av.AttributeView, ids string) bool {
    for _, id := range strings.Split(ids, ',') {
        if id = strings.TrimSpace(id); id != '' && attrView.GetView(id) == nil {
            return false
        }
    }
    return true
}

Try / catch

if _, err := validateTemplateAttributeViewNode(node, attrView); err != nil {
    if strings.Contains(err.Error(), 'visible view') {
        return fmt.Errorf('template references deleted view: %w', err)
    }
    return err
}

Prevention

When it happens

Trigger: Instantiating a template whose database block lists visible view IDs, one of which was deleted or renamed in the source attribute view.

Common situations: Templates exported before views were deleted, hand-edited visible-view-ID lists, or databases merged or modified after the template was saved.
