Author ComfyUI-LoRA-Manager nodes from the panel. Use when adding a LoRA Manager loader, stacker, prompt, or text node, or when panel_add_node refuses AUTOCOMPLETE_TEXT_LORAS / AUTOCOMPLETE_TEXT_PROMPT after waiting for a widget.

# ComfyUI-LoRA-Manager

[ComfyUI-LoRA-Manager](https://github.com/willmiao/ComfyUI-Lora-Manager) (willmiao)
registers Vue autocomplete widgets via `getCustomWidgets()`. Those widgets
are healthy in the ComfyUI menu, and drag-from-palette works, but **`panel_add_node`
cannot add the nodes that require them**.

The add-node guard polls `app.widgets` for a constructor. ComfyUI 1.49+ stores
`getCustomWidgets()` results in the frontend widget store, not on `app.widgets`.
The wait always expires after 5s. Reload, `panel_refresh_nodes`, and retry
**cannot** clear it. That refusal is not a missing pack.

## Which nodes `panel_add_node` will actually add

ComfyUI-LoRA-Manager

ComfyUI-LoRA-Manager (willmiao) registers Vue autocomplete widgets via getCustomWidgets(). Those widgets are healthy in the ComfyUI menu, and drag-from-palette works, but panel_add_node cannot add the nodes that require them.

The add-node guard polls app.widgets for a constructor. ComfyUI 1.49+ stores getCustomWidgets() results in the frontend widget store, not on app.widgets. The wait always expires after 5s. Reload, panel_refresh_nodes, and retry cannot clear it. That refusal is not a missing pack.

Which nodes `panel_add_node` will actually add

Works	Refuses (AUTOCOMPLETE_TEXT_*)
`LoRA Text Loader (LoraManager)`	`Lora Loader (LoraManager)`
core `LoraLoader`	`Lora Stacker (LoraManager)`
core `LoraLoaderModelOnly`	`WanVideo Lora Select (LoraManager)`
	`Text (LoraManager)`
	`Prompt (LoraManager)`

LoRA Text Loader (LoraManager) is the same backend as Lora Loader (LoraManager) (MODEL / CLIP / trigger_words / loaded_loras). The difference is the LoRA input: lora_syntax is a STRING socket (forceInput), so a regular string node or panel_set_widget can drive it.

Syntax (spaces or punctuation between entries):

<lora:lora_name:strength>
<lora:lora_name:model_strength:clip_strength>

Recipe — stack a LoRA from the panel

panel_add_node(class_type="LoRA Text Loader (LoraManager)"). Do not add Lora Loader (LoraManager); it will wait 5s and refuse.
Wire MODEL (and CLIP if you have one) through it.
Drive lora_syntax with panel_set_widget or a wired STRING, e.g. <lora:style/foo.safetensors:0.8>.
Put the node's trigger_words output into the prompt if the sidecar has any.

If LoRA Manager is not installed, use core LoraLoader and set lora_name / strength_model / strength_clip as usual.

Gotchas

The refusal names a tab reload. Do not follow that. The constructor will never appear on app.widgets.
panel_set_widget on text after a refused add never runs, because nothing was created. The working widget name is lora_syntax.
A freshly added Text Loader still needs lora_syntax written; an empty string loads no LoRA.

Empirical: the panel_add_node AUTOCOMPLETE_TEXT_* refusal, which nodes add cleanly, and the widget-store explanation from observed panel behavior in this repo.
