Failed to set 'self' context [message #1783915]

Hello,

I am walking through the online documentation on OCL.

I had a quick question on the Getting Started part.

I am executing the steps:

"You may evaluate custom OCL queries interactively. From the editor for Tutorial.xmi, invoke OCL->Show Xtext OCL Console from the context menu. Select Book b2 in the editor, then in the bottom line of the console enter the OCL expression loans.member and then Enter. The results are shown in the panel and identify that all three loans are by Member m3."

When I execute this I get a dialog box "OCL Console Selection Error" - Failed to set 'self' context. Reason: org.eclipse.xtext.completeocl.utilities.CompleteOCLASResourceFactory.getASElement

Also I see on the console:

Diagnostic ERROR source=org.eclipse.ocl.examples.debug.evaluation code=120 Execution failed data=[org.eclipse.ocl.examples.debug.vm.utils.VMRuntimeException: Execution failed]
[Java cause:]

at java.lang.Thread.run(Unknown Source)
Diagnostic ERROR source=org.eclipse.ocl.examples.debug.evaluation code=120 Execution failed data=[org.eclipse.ocl.examples.debug.vm.utils.VMRuntimeException: Execution failed]

Just wanted to know if this is expected, a problem of if I am doing something wrong.

Regards,
Bruce

Hi

No this is not what is expected. I see something very similar in my workspace. Thank you. I'll investigate.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=532591 came in yesterday and looks very adjacent to your observation. Are you a Mac 10.12.6, Eclipse Oxygen SR0 user?

Hello,

Just another piece of information. The dialog box I mention above pops up after a certain amount of time while walking throught the OCLinECore tutorial as well. Seems to come up when I make the OCLinEcore editor tab active.

Bruce

Hi

Thanks, but my only trouble with the repro is embarrassment at how solid it is.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=529886 explains why this has eluded testing.

Hi

The problems with the OCL debugger are fixed in the latest OCL I-build: http://www.eclipse.org/modeling/download.php?file=/modeling/mdt/ocl/downloads/drops/6.4.0/I201804111318/mdt-ocl-Update-I201804111318.zip

(A refactoring introduced an infinite recursion for any attempt to step into/over an iteration. The OCL debugger is now subject to a JUnit test.)

Great. Thanks.

Was this also the problem (as fix) with the OCL console and the unimplemented method I believe?

Hi

The UOE was a separate much more easily fixed problem. https://bugs.eclipse.org/bugs/show_bug.cgi?id=532666

M6 was 4 weeks ago. M7 is 4 weeks time. An I-build has all the latest fixes. http://www.eclipse.org/modeling/download.php?file=/modeling/mdt/ocl/downloads/drops/6.4.0/I201804111318/mdt-ocl-Update-I201804111318.zip
