Copying and pasting of elements that have a source and/or destination cause exceptions

[RyanMcilnay]

Summary

Copying elements from one container component to another such as mode transitions, connections, and flow specifications cause exceptions.

Expected and Current Behavior

Elements should be pasted into the destination component, instead, an exception is being thrown.

Steps to Reproduce

While viewing the package diagram:

1. Right click connection "c" in sys.impl
2. Select "Copy" from the context menu
3. Right click on sc.impl
4. Select "Paste" from the context menu

package CPBug
public
	system sys
	end sys;

	system implementation sys.impl
	subcomponents
		ss1: system sc.impl;
		ss2: system sc.impl;
	connections
		c: port ss2.o -> ss1.i;
end sys.impl;

	system sc
	features
		i: in data port;
		o: out data port;
end sc;

	system implementation sc.impl
end sc.impl;
end CPBug;

Environment

• OSATE Version: 2.8.0

This is caused by the recent refactoring. During it, we tightened the rules and checks regarding relative references. This is often being caused by transient or model errors.
