Embarking on your journey as a Mendix developer is both thrilling and daunting. The ability to create applications at lightning speed is at your fingertips, but so is the risk of making a mistake and breaking something. The fear of making mistakes can be overwhelming, especially when venturing into unfamiliar territory. But here’s the good news: mistakes aren’t just okay—they’re opportunities to learn and grow.

At the start of May 2024, Chelsea joined our ranks, and we couldn’t be more thrilled. With pride, we announce that Chelsea is the sole Mendix Certified Expert in Australia, bringing unparalleled expertise to our projects.
At CAPE, we’ve turned this mindset into a fun tradition called the “Meatball Meter.” Whenever someone makes a mistake, they earn a meatball for every hour it takes to fix it. At the end of each quarter, we tally up the meatballs and celebrate with a team lunch where everyone brings homemade meatballs to share. It’s a delicious way to turn mishaps into valuable learning moments—and let’s be honest, who doesn’t love a good meatball?
This tradition encourages an open culture where sharing mistakes isn’t just accepted but celebrated. By discussing what went wrong and how we fixed it, we not only grow as individual developers but also help our teammates avoid similar pitfalls.
Luckily, in Mendix, there are plenty of ways to undo an “uh-oh” moment before it earns you a meatball. In this blog, I’ll walk you through all the tools and tricks to recover from mistakes and get your project back on track.
Practical Tips for Undoing Mistakes in Mendix
Use the “Revert Change” Option in the Changes Panel
Mendix’s Changes panel keeps track of all the uncommitted changes in your app. If you realize you’ve gone down the wrong path with a specific change:
- Open the Changes panel.
- Right-click the unwanted change.
- Select Revert Change to undo it.
This is a great way to backtrack without impacting other parts of your project.
Revert All Changes in the Version Control Tab
If your uncommitted changes have spiraled out of control, you can undo everything:
- Go to the Version Control tab.
- Select Revert All Changes.
Revert a Commit in the Version Control Tab
For changes you’ve already committed, you can undo them by:
- Navigating to the Version Control tab.
- Right-clicking the commit you want to undo.
- Selecting Revert Commit.
This creates a new commit that reverses the changes from the original commit, ensuring your project history remains intact.
This restores your project to its last committed state, giving you a clean slate without requiring a full project reset.
Fixing External or Corrupt Errors: Throw Away the Project Folder
If you’ve made changes that result in errors you can’t solve—such as conflicting libraries or unexpected compile issues—and you haven’t committed those changes yet, don’t panic.
Simply:
- Close the Mendix modeler.
- Navigate to the project folder on your local device.
- Delete the folder entirely.
- Reopen Mendix Studio Pro and retrieve the project again from the Team Server.
This clean slate approach is especially useful when you’re stuck with errors that feel insurmountable. This also highlights the importance of always running your application locally before committing to catch compile errors early. This practice helps identify and resolve issues before they become part of your project’s history.
Building a Culture of Growth
Mistakes are inevitable, especially when you’re learning something new. By leveraging Mendix’s powerful tools to recover from errors and fostering a team culture where mistakes are seen as valuable learning opportunities, you’ll build confidence in your development journey.
So the next time you’re staring at a compiling error you can’t solve, remember: there’s always a way to undo the damage—and maybe a chance to share a great lunch with your team.
