Hi! I am a newbie on Mendix, but I have some experience with java, Mysql and OpenXava. When trying to publish my app from Studio pro (Yes, by hitting the button ‘Publish’), the application never deploys. When trying to open the app, it just stays asleep. I found the environment logs, and I notice the following error: App Error: Executing start did not succeed: result: 1, message: An error occurred while initializing the Runtime: Cannot copy data from source database to current database, because the source database does not exist, caused by: Cannot copy data from source database to current database, because the source database does not exist Any suggestions? Hallvard P.S. I am using Studio pro 9.4.0. I am able to publish other, simpler apps with no problems.
