Hi,
I am trying to setup an OCL constraint in the GMF Map and am getting an
error when trying to validate or generate code using it. This constraint
does work in the OCL interpreter:
> self.connectorType = metadata::ConnectorType::Input
The Background:
in package metadata
enum ConnectorType {Input, Output}
in package graph
class Connector
property connectorType: ConnectorType
class Processor
property connectors: Connector
The constraint is on a connector, and my feeling is that the error has
to deal with accessing the other package, but the expression does return
a true when clicking on a connector and running it in the ocl interpreter.
Any help will be appreciated.
Thanks!
Regards,
Vineet

Hi, Vineet,
What is the error message that you see? That should help to diagnose
the problem.
Cheers,

Sorry I meant to include this earlier. The error message is:

Thanks for looking into this!

Hi, Vineet,
Right, this is what you had indicated: the qualified reference to your
enumeration literal cannot be resolved.
Either your metadata EPackage is not registered in the package registry
used by the OCL Environment employed by GMF for audit constraints, or it
is registered in the static package registry but resides there still as
a PackageDescriptor. Until the package is looked up in the registry by
its namespace URI (and thus the descriptor replaced by your package
instance), OCL will not be able to find the EPackage named 'metadata'
You might try debugging the
EcoreEnvironment::findPackage(List<String>, EPackage.Registry)
method to see why this qualified name isn't being resolved as you expect.
HTH,
Christian

How would I get GMF to do the appropriate registering? As a side note, I
was able to get the constraints working using the Java option in GMF.
Perhaps GMF's integration of OCL has a bug in it?

How?
Are you suggesting somehow setting up the OCL interpreter in the
development workspace (as opposed to the runtime workspace)?
Thanks!

It isn't up to GMF to register EPackages; your EMF model plug-in does
that. Note that Java code doesn't have to worry about whether the
EPackage descriptor is resolved in the registry, because it doesn't rely
on the registry to look up meta-data.

Using a breakpoint in JDT's debugger. Step through the findPackage
algorithm to see what the package registry contains.

No. The OCL interpreter has nothing to do with it.
