Steps to reproduce

  1. Navigate to any app detail page (e.g., /app/{app-id}/configuration)
  2. Hold Cmd (Mac) or Ctrl (Windows/Linux) and click on a navbar link like "Knowledge"
  3. Observe the new tab opens correctly
  4. Switch back to the original tab

✔️ Expected Behavior

The original tab should remain on the app detail page (/app/{app-id}/configuration) with all state intact, while the new tab opens the clicked link.

❌ Actual Behavior

The original tab shows a loading spinner and gets stuck. The app detail state is cleared, making the page unusable.

Hi @lequocbinh04! I'm Dosu and I’m helping the dify team.

This bug happens because the navbar's click handler always calls the setAppDetail() function, which clears the app detail state—even when Cmd/Ctrl+click is used to open a link in a new tab. The onClick event fires in the original tab, so the state is reset and the page gets stuck loading, matching what you observed. There’s currently no logic in the navbar code to detect modifier keys and prevent this state clearing when opening links in a new tab, which is why the issue occurs. You can see this in the navbar component code: the onClick handler always runs, regardless of how the link is opened (source).

A possible fix is to update the click handler to check for modifier keys (event.metaKey for Cmd, event.ctrlKey for Ctrl) and skip clearing state if the user is opening the link in a new tab or window. As a temporary workaround, right-clicking the link and choosing "Open in New Tab" may avoid the bug, since it doesn't trigger the onClick handler in the same way.

The relevant code is in web/app/components/header/nav/index.tsx and web/app/components/header/nav/nav-selector/index.tsx, and state is managed with Zustand in web/app/components/app/store.ts (source).

To reply, just mention @dosu.
