gnodet opened a new pull request, #24280:
URL: https://github.com/apache/camel/pull/24280
## Summary
_Claude Code on behalf of forgebot_
Fixes missing pane borders in the TUI dashboard. TamboUI's `Block` widget
requires **both** `.borderType()` and `.borders(Borders.ALL)` to render border
characters. All 131 `Block.builder()` calls across the TUI module were missing
`.borders(Borders.ALL)`, causing no rounded border box-drawing characters
(`╭╮╰╯│─`) to render around any pane.
**Before (no borders):**
```
Routes sort:name
ROUTE FROM STATUS AGE TOTAL FAIL
route1 timer:// Started 10s 0 0
Processors [route1]
TYPE PROCESSOR TOTAL FAIL
log log1 50 0
```
**After (borders restored):**
```
╭ Routes sort:name ────────────────────────────────────╮
│ ROUTE FROM STATUS AGE TOTAL FAIL │
│ route1 timer:// Started 10s 0 0 │
╰──────────────────────────────────────────────────────╯
╭ Processors [route1] ────────────────────────────────╮
│ TYPE PROCESSOR TOTAL FAIL │
│ log log1 50 0 │
╰──────────────────────────────────────────────────────╯
```
### Changes
- **36 source files**: Added `.borders(Borders.ALL)` after every
`.borderType(BorderType.ROUNDED)` call and added `import
dev.tamboui.widgets.block.Borders`
- **1 new test file** (`BorderRenderTest.java`): 17 rendering tests that
render tabs into a virtual terminal buffer via `Frame.forTesting(Buffer)` and
verify border characters appear at the correct positions
### Test Coverage (BorderRenderTest — 17 tests)
- HealthTab: top/bottom corners, vertical/horizontal borders, complete box
formation, left/right border alignment
- RoutesTab: full border box, dual pane borders (routes + processors),
separate borders for each pane, non-overlapping borders
- ErrorsTab: border box with data, border box in empty state
- No-selection: border in unselected state
- ShellPanel: border rendering when panel is open
- Border type validation: `BorderType.ROUNDED` characters match expected
Unicode codepoints
- Corner alignment: `╭`/`╮` on same row, `╰`/`╯` on same row
## Test plan
- [x] All 248 tests pass locally (231 existing + 17 new border tests)
- [x] Rendering tests validate actual border characters (`╭╮╰╯│─`) in the
virtual terminal buffer
- [x] Code formatted with `mvn formatter:format impsort:sort`
- [ ] CI build passes
