Perhaps “limit to current tab” is enabled in the Errors panel. If that is the case, only the errors of the document you are looking at show up.
When I commit I got the following popup: “The project contains errors. Do you still want to commit?”
After committing the buggy version still no error messages in the error list
Next step: enable app for Mendix Studio. No errors shown yet
Click on preview resulting in : Your app has consistency errors, click here to view them. And it shows the errors. This time it is language related. I have installed a second language and have empty captions for a language
That is a weird error. Since it is possible that this is a Mendix bug, you might consider reporting this to firstname.lastname@example.org
Also, possibly there is something wrong with one of your navigation profiles. Try removing the navigation profiles for Native and for Hybrid, just to see if the error goes away.
Few things that you can try.
Do a build process again.
Sometimes you get error in runtime if there is permission error on some entiry/page. If it happens, check how the flow is going to that component/page/microflow and debug for what is giving the security error.
