Second navigation button with identical label does not trigger any panel refresh or navigation

[NullWan]

Environment

• WinCC OA Version: 3.20.12
• Project: WinCCOAFrameworkAppExample

Issue Description

When two navigation menu buttons share the exact same display label but are configured to open different target panels, the first button behaves correctly and refreshes the page to show its associated panel. However, clicking the second button results in no response at all — the current panel remains displayed and no navigation or refresh occurs.

Steps to Reproduce

1. Create two navigation menu entries with identical display text but different underlying target panel configurations.

2. Click the first button.

• Expected: The page refreshes to display the panel associated with the first button.

• Actual: The page refreshes correctly.

3. Click the second button.

• Expected: The page refreshes to display the panel associated with the second button.

• Actual: Nothing happens. The GUI does not refresh, and the panel opened by the first button remains visible.
