12 years ago Hi Philip,
Thanks for letting me know. I'll look into it. I had resolved the issue for classifiers. I have seen yours in one context and I think it is due to a cyclic dependency between two (or three) predeclared property sets (AADL_Project and Memory and maybe one more). I may have to resolve it to move things around between them (which means I am changing something in the standard itself since it documents those property sets).
Peter
-----Original Message----- From: philip-alldredge [mailto:reply@reply.github.com] Sent: Friday, March 30, 2012 2:10 PM To: Peter Feiler Subject: [osate2-core] Cyclic resolution error (#44)
Under certain circumstances, I am receiving a "Cyclic resolution of lazy links : NumberType.unitsType->NumberType.unitsType" exception when calling GetProperties::lookupPropertyDefinition().
The property being looked up is a enumeration property in a custom property set.
To trigger the issue, I run a plugin that uses a AadlProcessingSwitch to update the connections contained in certain Concept Implementations. This triggers a rebuilding workspace. After that, I activate a custom plugin that tries to call the GetProperties::lookupPropertyDefinition on a InstanceObject.
After the first exception I can try to run my plugin again and it will not trigger the exception a second time. Stacktrace below.
