C# Creating sub-packages gives TargetInvEx

[Dan Glasser]

I'm attempting to automate the creation of a diagram (particularly interested in DoDAF).  I am stuck on creating sub-packages.

I get the error "EA_MenuClick: Attempted to read or write protected memory.  This is often an indication that other memory is corrupt". when launching an AddIn that is simplified to the following code.  The error occurs when Updating the sub-package:

Code: [Select]

           Package rootNode = (Package) repository.Models.AddNew("MyRootNode", "");
            if (!rootNode.Update())
            {
                MessageBox.Show("Error updating package: " + rootNode.Name + " " + repository.GetLastError());
            }
            repository.Models.Refresh();

            Package example = (Package)rootNode.Packages.AddNew("Example Enterprise", "");
            if (![highlight]example.Update()[/highlight])
            {
                MessageBox.Show("Error updating package: " + example.Name + " " + repository.GetLastError());
            }

I am on version 7.1.832.  Any help is appreciated.

Dan,

- Have you tried to indicate the type of element you are adding?
so AddNew("Example Enterprise","Package")?
- Try without the line repository.Models.Refresh(); (that doesn't do any good anyway)

Geert,

Thank you for the suggestion.  Yes, I've tried changing the type.  The type "Package" yields the same result.  For what it's worth it the operation crashes EA but upon reloading the project the package/sub-package does exist.

Hi Dan,

In the release notes for 833
....
Resolved issue calling Package.Update.

Alistair,

Thank you.  I tested the trial version of EA 8 and verified it worked and then located a copy of 7.1.834 and verified that it works there as well.  Thanks for your support.
