Warning: unable to resolve references

[dlane]

One of my students has a file saved from yesterday that worked fine, and now it's giving this message with a gigantic list of stuff when you open the file. Is the file just corrupted, and there's no hope of fixing it?

edit: Ok apparently you would normally get a message that would let you set the problem values/methods or whatever to "none" but the list was so long the OK button wouldn't show up.

Can you upload the file so we can take a look at it?

I just had that problem the other day. It pops up when you try to delete an object which is being referenced in a method or an event. Try manually removing the refeences if restarting Alice won't work.

For long lists, use the tab button and guesswork to find the okay button.

For references, you can also use a remove automatically command, but that can cause problems if you don't catch all of the references to the <None> and delete them (which is why the world in question had problems).
