Hey all,
I’ve gone through the user registration sample three times now, using a new project each time, and building more on it each time. After updating to the new CUBA Studio and using the newest CUBA version, I’m getting an error when clicking on the link to register. The error simply says “Please Contact the System Administrator”.
The log file shows this:
21:25:56.761 ERROR com.haulmont.cuba.web.log.AppLog - Exception in com.haulmont.cuba.web.widgets.CubaButton:

It’s possible I forgot to do something, but I’m not sure if that’s it. The strange part is that it allows me to continue after the error message and everything seems to work correctly. I’m wondering if somebody can help me interpret the problem.
Thanks!
