Cascade Broke Thymeleaf Template Rendering
HTML pages fail to render after Cascade modified Thymeleaf templates. Error pages show template processing exceptions instead of actual content. The application shows 'Thymeleaf template not found' or 'variable not available in context' errors.
Cascade likely broke variable references or modified template structure incorrectly.
Error Messages You Might See
Expression parsing error: 'variable'
Template not found: dashboard.html
No getter for 'userName' in class
Thymeleaf template error line 45
Common Causes
- Cascade changed variable names in controller but not in template
- Thymeleaf attribute syntax error: th:text='${missing.variable}'
- Cascade removed template file or moved it without updating references
- Cascade modified model and didn't add required attributes
How to Fix It
Check error messages for variable names that don't exist. Verify model attributes are added in controller with model.addAttribute(). Review git diff for template changes. Use IDE validation for Thymeleaf syntax. Test page rendering with debug logging enabled to see model contents.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

How do I debug Thymeleaf errors?
Enable server logs to see error details. Use [[${variable}]] to inline variables. Check controller adds model attributes.
How do I check variable exists in Thymeleaf?
Use th:if='${variable != null}' or th:if='${variable}'. Check controller model.addAttribute() calls.
