Hi again matteo,
With your instructions, I did reproduce the error you mention. Not only that, but found a couple of issues with "issues" as well:
1. If I display the project issues (created through Project -> Issues) by Alt + 2, these are displated under a "Model issues" tab. I completely agree with you, this is misleading: these should not be named "model issues", since the Project -> Issues dialog clearly says on that these are "Project issues".
2. In the Project -> Issues dialog, there is no way of changing the priority of issues, which are always created with a "2: Medium" priority.
I have to admit that, although I have been using EA heavily during the last ten months or so, I had never displayed the project issues by Alt + 2.
I had always created model issues by dragging the "Issue" icon into a diagram. (By the way, I keep all model issues on an appropriately named package.) I do have to remark that these issues (which I consider as proper "Model issues") never appear together with project issues: they don't come out in the Project -> Issues dialog, nor in the RTF document created in this dialog, nor in the Alt + 2 display.
So, although these are minor "issues on Issues" (albeit confusing ones, as you correctly point out), we should all thank you for raising them.
If you follow this forum for a minimum a ammount of time, you will see that Sparx is very responsive.
