Hi,

My eclipse mars on mac os x can-not open most of the xmi files. Those files open in my another eclipse mars on windows.
e.g. I have the below errors:
index.php/fa/29500/0/

index.php/fa/29501/0/

what should I do?

Is there any more detail about why the Families.ecore won't load? What are the contents of that file?

It loads fine for me (on Windows). Is there something in the Error Log view that might provide a clue? Are there really no "child problems", in the problems tab for the *.ecore?

There is no child problems. When I click on the problem this message showed:

That doesn't look like a problem that would come from the *.ecore model itself, especially not the one you attached. Have you tried creating the markers and looking at where the markers are in the text editor? There is a button to open the text editor...

Hi

"ember" looks suspiciously like an off-by-one reference to "Member".

I recall very similarly problems occurred about 5 years ago with Acceleo's autogenerated model that was generated within Eclipse and consumed outside Eclipse. The problem was hard to reproduce and seemed to go away with forcible rebuilds.

I wonder if your use of Mac is revealing a new-line representation sensitivity that has gone largely unnoticed.

I suggest creating a similar file on the Mac and using compare of some similar tool to examine the whitespace carefully.

Regards

Ed Willink

Hi

More likely a CharSet bug. Internally Java uses multi-byte characters, but since we nearly always use plain ASCII a byte[] is adequate allowing lazy programmers to just convert between a Stream's bytes and Java strings using toString() or getBytes(). However externally a variety of encodings are possible requiring the correct Charset encode/decode to map between multi-byte sequences and Characters. An obscure EMF/SAX bug in this area would explain the problem. But possibly there is a contradiction between the character encoding claimed by the XML prolog that you copied from Windows and the physical file representation that your Windows to Mac copy utility provided. Have a look at your file properties and see if they are consistent with the XML prolog. If not please raise a Bugzilla with the repro. Perhaps there is a simple conflict test that EMF/platform could do to help users here.

Regards

Ed Willink

I do-not know how can I create these markers. When I click on Create Markers on problem tab no happens.

When I click on ecore tab I see the below image. It is like a `Sample Reflective Ecore Model Editor` but I open it as `Sample Ecore Model Editor`.

index.php/fa/29529/0/

Its charset is UTF-8.

I notice that you're showing Families_Extended.ecore in this situation but previously you attached a different file. This also appears to be a different project than before. So you appear to be using resources you've not previously shared.

Trying various ways to reproduce your problem I did noticed that org.eclipse.emf.ecore.xmi.impl.XMLHandler.setValueFromId doesn't not explicitly handle exceptions from calls to org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObject so such problems will abort loading rather than simply be recorded as a problem in Resource.getErrors() and otherwise ignored. So the ability to diagnose the cause is much poorer than it should be. That's what results in the issue being reported in the Error Log.

I'd suggest you open a Bugzilla, attach the exported projects that reproduce this problem to that Bugzilla, and then we can be clear on what exactly you're doing. So far you've not provided sufficient detail to reproduce the problem.

This happened for all my ecore and xmi files in any projects.

When I switched to an empty workspace the problem was solved.
Thanks for your time.
