name: glue-add-object-flow description: Glue's "New Object" add pipeline and the tree's inline-rename mechanism. Triggers: AddObjectViewModel, ShowAddNewObjectDialog, NewObjectTypeSelectionControlWpf, IsTypePredetermined, NodeViewModel.IsEditing, RenameNamedObjectSave.

Glue Add-Object Flow

Adding a NamedObjectSave and renaming one in the tree are two separate code paths that share validation logic. See [[glue-task-manager]] for how each path's save/codegen work gets queued.

File Map

File	Role
Glue/Controls/NewObjectTypeSelectionControlWpf.xaml(.cs)	"New Object" modal — type radios, filtered type list, name box
Glue/ViewModels/AddObjectViewModel.cs	Backing VM; SetDefaultObjectName() auto-generates a unique name; IsTypePredetermined/IsSelectionEnabled/IsObjectTypeGroupBoxEnabled gate which controls are enabled
Glue/Plugins/ExportedImplementations/CommandInterfaces/DialogCommands.cs	ShowAddNewObjectDialog / CreateAndShowAddNamedObjectWindow — shows the modal, validates the name after it closes
Glue/Plugins/ExportedImplementations/CommandInterfaces/GluxCommands.cs	AddNewNamedObjectToSelectedElementAsync → AddNewNamedObjectToAsync → AddNamedObjectToAsync (actual add); RenameNamedObjectSave (separate rename path)
OfficialPlugins/TreeViewPlugin/ViewModels/NodeViewModel.cs	IsEditing toggle drives in-place tree rename; HandleRenameThroughEdit dispatches by Tag type (GlueElement/ReferencedFileSave/NamedObjectSave/folder)
OfficialPlugins/TreeViewPlugin/Logic/RightClickHelper.cs	RenameItem() — SelectionLogic.Current.CurrentNode.IsEditing = true is the whole mechanism for entering inline rename

Gotchas

• IsTypePredetermined (set when adding to a typed list, or explicitly by the caller, e.g. HandleAddLayerClick) drives IsSelectionEnabled => !IsTypePredetermined, which disables both the type radio group and the type list, not just one. CreateAndShowAddNamedObjectWindow checks the final value of this flag (it can be narrowed later, e.g. AvailableEntities.Count < 2 for a typed list whose generic type has derived entities to choose from) and skips constructing the WPF window entirely when true — adds immediately with the SetDefaultObjectName() default, no modal shown at all. RightClickHelper.AddObjectAndBeginRename() then drops the new tree node straight into inline rename.
• IsOkButtonEnabled only checks SelectedItem != null — it was never gated on name validity. The name field itself no longer exists in NewObjectTypeSelectionControlWpf.xaml; naming happens via inline tree rename after add, not before.
• DialogCommands.ShowAddNewObjectDialog no longer calls NameVerifier.IsNamedObjectNameValid before adding — the name is Glue's own computed default at that point, not free-typed input. It still checks RecursionManager.Self.CanContainInstanceOf (unrelated to naming).
• Double-clicking a type in the list (StrongSelect) immediately confirms the dialog with whatever's in the name box — no Enter/OK click needed.
• Tree inline rename validates via NameVerifier and reverts on invalid input inside NodeViewModel.HandleRenameThroughEdit → GluxCommands.RenameNamedObjectSave — the same validation the Add path uses, so chaining add → immediate rename stays safe.
• Chaining Add then Rename queues two independent SaveProjectAndElements(AddOrMoveToEnd) calls with different DisplayInfo, so per glue-task-manager's coalescing rule they run as two separate save/codegen passes, not one.
• AddNewNamedObjectToAsync and AddNamedObjectToAsync's own TaskManager.Self.AddAsync calls both use TaskExecutionPreference.Asap, not the AddAsync default of Fifo — the add is a direct user-triggered action AddObjectAndBeginRename depends on completing immediately, not something that should sit behind unrelated Fifo-tier work. Bumping the inner (nested) call is defensive rather than strictly required — see glue-task-manager's note on why a nested AddAsync call runs inline regardless of its own preference.
• RightClickHelper.AddObjectAndBeginRename() is the single shared entry point for the tree's own "Add Object"/"Add Layer" menu items and the Ctrl+N shortcut (MainTreeViewControl.xaml.cs) — it calls ShowAddNewObjectDialog, then SelectionLogic.Current.SelectByTag/.IsEditing = true. DragDropManager.cs's drag-and-drop add and QuickActionPlugin's add call ShowAddNewObjectDialog directly instead (they get the modal-skip but not the auto-inline-rename trigger, since SelectionLogic is internal to the TreeViewPlugin assembly and unreachable from those projects).
