Boolean List Hierarchy Get

You built a big Boolean List Hierarchy - the tree with Root → child → grandchild switches - and now you're in a different part of the canvas and you want the state of one root branch over there. Dragging a wire all the way across a busy workflow is exactly the legibility problem every reroute exists to solve. Boolean List Hierarchy Get is DAELab's answer for this specific case: it references a root branch of a Hierarchy by ID, with no wire from the source node at all.

The trick is in the name and the framing: it's the "Get" side of a "Set/Get" pattern. The Hierarchy holds the tree; this node selects which branch of it you want and re-emits that branch's boolean outputs locally, right where you need them. The source isn't connected - the node knows the source node's ID and which root branch you picked, and it pulls the current state from that.

How it works

The backend takes a config_json input that carries the wiring metadata: the source node's ID (source_node_id), the chosen root item (root_item_id), whether the root itself is included in the output (include_root), and the list of output item IDs. On execute it resolves that branch, including any cross-branch dependency context the branch needs to be valid, and emits the booleans on the same fixed 64-socket layout as the other boolean-list nodes. The front-end (web/boolean_list_hierarchy_get.js) gives you a picker for choosing the root branch, so you select from a dropdown instead of memorizing node IDs.

The inputs and outputs that matter

• config_json - the reference metadata (which Hierarchy, which root branch). Managed by the picker; you won't hand-edit it. Defaults to an empty/invalid reference until you pick a branch.
• The 64 BOOLEAN outputs - the branch's switches, available locally. Wire them anywhere you'd wire the source node's own outputs.

This is the sibling of Boolean List Hierarchy, and it's the natural pairing for the Boolean Group Bypass Controller too: Get a branch locally, feed its booleans to the controller, drive group bypass without crossing the whole canvas with wires.

How to install it

Standard DAELab-pack install. ComfyUI Manager, search "ComfyUI-DAELab-Custom-Nodes-Library", or:

cd ComfyUI/custom_nodes
git clone https://github.com/TeutonicMepheles/ComfyUI-DAELab-Custom-Nodes-Library

then restart. No models, no extra dependencies. Keep ComfyUI Core current (V3 node), and install the full repo so the branch-picker front-end loads.

Common issues & troubleshooting

"The picker won't let me select a branch." The Get node needs a Hierarchy to reference. It works by node ID, so it only finds sources that exist in the same workflow - a Hierarchy in a different saved workflow won't be referenceable.

"It outputs nothing / all False." A stale reference. If the source Hierarchy's IDs changed (the tree was rebuilt or properties stripped), the root ID this node remembers no longer resolves. Re-pick the branch in the front-end and re-save.

"I edited the Hierarchy but this node didn't update." It resolves on execution - it's not a live link. Run the workflow (or force a refresh of this node) and the current state comes through.
