Cascade Removed Form Validation Logic
Form validation is completely broken after Cascade refactored form submission code. Invalid data is being accepted, required fields show no validation errors, and server receives malformed data.
Cascade likely removed validation logic thinking it was redundant or simplified the submission handler.
Error Messages You Might See
Common Causes
- Cascade removed client-side validation JavaScript without preserving validation logic
- @Valid or @Validated annotations removed from controller endpoints
- Cascade deleted custom validator classes or JSR-380 constraint annotations
- Form error display elements (span.error) removed from templates
How to Fix It
Add back form validation: client-side with HTML5 attributes or JavaScript, server-side with @Valid on @RequestBody. Implement BindingResult parameter in controller to capture validation errors. Display error messages in form templates. Test with invalid inputs to ensure validation triggers.

How do I add server-side validation?
Add @Valid annotation to controller method parameter and BindingResult to capture errors. Check bindingResult.hasErrors().
What are JSR-380 constraints?
@NotNull, @NotBlank, @Email, @Size(min=,max=), @Pattern(regexp=), etc. from jakarta.validation.constraints
