Groot2 1.9.0: Switch2 built-in model contains duplicate case_1 input port

[soohwan-justin]

Description

In Groot2 1.9.0, the built-in Switch2 model displays four input ports:

• case_1
• case_2
• case_1 (duplicate)
• variable

The duplicate is present in Groot2's embedded builtin_nodes_v4.xml, rather than in the user's project model.

Steps to reproduce

1. Start Groot2 1.9.0 in Editor mode.
2. Find or insert the built-in Switch2 control node.
3. Inspect its input ports.

Actual embedded model

<Control ID="Switch2">
    <input_port name="case_1" type="std::string"/>
    <input_port name="case_2" type="std::string"/>
    <input_port name="case_1" type="std::string"/>
    <input_port name="variable" type="std::string"/>
</Control>

Expected model

<Control ID="Switch2">
    <input_port name="case_1" type="std::string"/>
    <input_port name="case_2" type="std::string"/>
    <input_port name="variable" type="std::string"/>
</Control>

BehaviorTree.CPP's SwitchNode<2>::providedPorts() and the output of bt4_nodes_model --include-builtin both contain the expected three distinct ports, so the issue appears isolated to Groot2's bundled v4 node-model resource. The bundled definitions for Switch3 through Switch6 are also correct.

Suggested fix

Remove the second duplicated line:

<input_port name="case_1" type="std::string"/>

from the Switch2 entry in builtin_nodes_v4.xml.

Environment

• Groot2: 1.9.0
• OS: Ubuntu 20.04.6 LTS
• Architecture: x86_64
