Project File Corrupting (#473)


I am finding in Version 10 when opening a project it is sometime corrupted, and Elements are not displayed on diagrams and appear as blue circles in the project browser. Attempting to look at the properties causes an error (details Below). This situation is non-recoverable and I have to delete the Objects from the project or restart with a new project file (the problem is also in the backup file). I will e-mail you a screen shot plus the *.simp file.

System.NullReferenceException: Object reference not set to an instance of an object.

Hello Richard,

It seems that the problem can cause the version 9. There was a bug when combination of editing actions could lead to this project inconsistency. The issue was fixed in version 10 - (from release notes: "Fixed deleting elements when deleting repository and elements are used on other diagrams - now the used elements are moved from the deleted repository to the project repository" )

However, I will continue with investigation to be sure there is not another reason for this problem.

I am having a similar problem. Built a project in 10.42. I tried to load it in version 10.68. Gives errors. If I try to export in version 10.42 I get

System.NullReferenceException: De objectverwijzing is niet op een exemplaar van een object ingesteld.

Firstly, I apologize for this problem.

If it is possible, could you send me your project to to analyze the exact cause? If it is not possible, could you please let me know which diagram types was used in this project?
