Hey Rod,
I’m not sure about your specific questions (1-4), but I can help you with the last one.
You’ll probably want to try logging in as MxAdmin with a password of ‘1’ (This can be edited in Project module → Security → Administrator tab → Password field). That will allow you to get into the app, and you should be able to give yourself access to the included ‘Account_Overview’ page which will then allow you to create new local users you can test things with.
You can either ctrl+g and type in ‘Account_Overview’ to find the page or get to it by going to → Project module → App Store modules → Administration module → User Management folder → Admin folder → Account_Overview page.
I hope that helps even just a little bit. It’s been a while since I’ve gone through the course, so I don’t know about the specifics. Sorry I couldn’t help out more, but if you break down the issues for me in a Mendix specific way instead of a learning module specific way I may be able to help!
Q1) No. That particular attribute is named 'Description’ and is not added to the Tile. That is why you do not see it.
Q2) That is probably the intention but also probably a bug in the course. No one gets assigned. Nothing happens.
Q3) Answers are the same as Q1 and A2
Q4) Indeed the percentage will stay on 0. You will only get it to move if you set one of the two Todo-items to status Done. It will become 50%. Adding another item and setting that to do too, gets you 67%.
So some minor glitches in the course, but it is a pretty neat tutorial and I think you get the drift of the application.
Minor additional clarifications:
