I try to open a project in 2016R1.1. The first time i opened it (when I started browsing the views in the project it crashed (feedback case 43689).
Then I opened it with 2015R4.1 and saved it with it. Now when I try to open it again with 2016R1.1 it displays the message: “Unable to open project correctly. This project requires a newer version of Xojo to open it properly.” !!!
Then it crashes!
I don’t have this issue with 2016r1.1, but my project was previously upgraded to, and saved with, 2016r1 so that might be a difference? I wish you good luck with finding a solution to this.
This CAN happen once in a while when upgrading to a new Xojo Version.
I would make a FR and attach the “broken” Project. Then open a Backup of the Project using 4.1 and save it in another Format (XML, Text, Binary) and try to open this Copy again in 1.1.
I pinpointed that a specific view is causing the “interesting” message and the crash. I will see what I can do about it (maybe use an older version, or save it as binary and then again as Text) and let you know what happens…
As I said the problem was an iOSView class. The only way to solve it was to create a new iOSView Class, copy everything through BBEdit, and then it worked!
I sent the crashing view file and the working view file to Xojo to see what was causing the crash…
Saving the project to another format didn’t solve the problem…
