ID 163807 - The recurseGroups parameter doesn't work if a filter is specified in the nuke.allNodes() function

Problem summary
The recurseGroups parameter doesn't work if a filter is specified in the nuke.allNodes() function.

Customer reported version
Nuke 15.2v4

Customer reported platform
Rocky 9

Steps to reproduce

1) Open Nuke.

2) Create a few Transform nodes.

3) Add them to a new Group (select them and press Ctrl+G).

4) Run the following code in the Script Editor:

nuke.allNodes("Transform", recurseGroups=True)

Expected behaviour
The code should return a list of Transform nodes within the Group.

Actual behaviour
The code returns an empty list in this case. When a filter is specified, nuke.allNodes() only searches the root level.

Workaround
You can do this in two steps by recursing through the groups, then querying node.Class(). For example:

[node for node in nuke.allNodes(recurseGroups=True) if node.Class() == "Transform"]

Reproduced by support
