[PR] WW-3429 Add configurable checkbox hidden field prefix [struts]
lukaszlenart opened a new pull request, #1570:
URL: https://github.com/apache/struts/pull/1570
## Summary
- Add `struts.ui.checkbox.hiddenPrefix` constant to allow configuring the checkbox hidden field prefix
- Default value `__checkbox_` maintains backward compatibility
- Addresses HTML validation warnings about double underscores (HTML Tidy)
- Users can set `struts_checkbox_` or other prefix for HTML5 compliance
Fixes [WW-3429](https://issues.apache.org/jira/browse/WW-3429)
## Changes
| File | Change |
|------|--------|
| `StrutsConstants.java` | Add `STRUTS_UI_CHECKBOX_HIDDEN_PREFIX` constant |
| `default.properties` | Add default value `__checkbox_` |
| `Checkbox.java` | Inject constant, pass to template |
| `CheckboxInterceptor.java` | Inject constant, use in prefix matching |
| `simple/checkbox.ftl` | Use `${attributes.hiddenPrefix}` |
| `html5/checkbox.ftl` | Use `${attributes.hiddenPrefix}` |
| `CheckboxHandler.java` | Get prefix from component parameters |
| `CheckboxInterceptorTest.java` | Add tests for configurable prefix |
| `CheckboxTest.java` (javatemplates) | Fix test for correct hidden field value |
## Configuration
**Default (backward compatible):**
No configuration needed - uses `__checkbox_`
**HTML5 Compliant:**
```xml
<constant name="struts.ui.checkbox.hiddenPrefix" value="struts_checkbox_"/>
```
Or in `struts.properties`:
```properties
struts.ui.checkbox.hiddenPrefix=struts_checkbox_
```
## Test plan
- [x] Run `CheckboxInterceptorTest` - 12 tests pass
- [x] Run `CheckboxTest` (core) - 21 tests pass
- [x] Run `CheckboxTest` (javatemplates) - 6 tests pass
- [ ] Manual verification with showcase app
