Bug 289660

Description Ed Willink 2009-09-16 17:13:31 EDT

From news://news.eclipse.org:119/h8rf01$lli$1@build.eclipse.org

I tried this on the EXTLibrary example and get the same error for simple OCL expressions.

1.  I installed eclipse-modeling-galileo-incubation-win32.zip
2.  I start and switch to the Plug-in Development Perspective
3.  I switch to the Plugins tab and import as source org.eclipse.emf.ocl.examples
4.  I then Import "Existing Projects into Workspace" for each of the zip files: interpreter.zip, library.zip, libraryEdit.zip, and libraryEditor.zip and get four projects that build properly.
5.  I run the Editor project, which launches an Eclipse Runtime.
6.  I create a new EMF Project, and then create an EXTLibrary Model.
7.  In the Editor, I add a Library Child and give it a name.
8.  I right-click on the Library Node, and start the OCL Interpreter.
9.  In the bottom pane (the SourceViewer), I enter: name and then hit enter.  In the TextViewer pane, I see the Results with the correct information for the name displayed.
10. I want to save this OCL Expression to an xmi file and click on the Save button.  I select a directory and create a new file name.  When I hit OK, I get the ERROR dialog:
OCLConsole Saving Error: The 'no duplicates' constraint is violated

---

It appears that the addition of 

		// persist the expression
		persist(env, result);
		
		// dispose the remainder of the constraint
		ObjectUtil.dispose(constraint);
		
by Bug 219051 is the culprit. Possibly just needs the duplicate save in OCLResource.save to be removed; but why are there also two self variables?

Why did no JUNit test that catch this?
