Dear Mr. Osman, many thanks for pointing this out. This was a bug in the SDK that was not caught because a special case was not considered
in an unit test. I added a test case and fixed this bug. You can pull the latest update, rebuild the SDK and then, the example will work. Best regards, Frank Schnicke -- Frank Schnicke Project Manager Dept. Embedded Software Engineering Fraunhofer IESE

Dear Mr. Schnicke, I am using the basyx sdk as part of my bachelor thesis project and have been getting to know it through the Introductory Examples that you have thankfully uploaded to https://wiki.eclipse.org/BaSyx_/_Introductory_Examples. I have encountered a small problem while running Example 2 (https://wiki.eclipse.org/BaSyx_/_Introductory_Examples_/_Java_/_Example_2)
on my machine and wonder if you have an idea of what the reason could be. While the temperature value is successfully retrieved with ( connectedOven.getModelPropertyValue("/properties/temperature");), the following error/exception occurs after the invoke Operation in connectedOven.invokeOperation("/operations/activateOven"): 04:10:06.252 [http-nio-4001-exec-7] DEBUG org.eclipse.basyx.vab.protocol.http.server.VABHTTPInterface - Exception in HTTP-POST. Response-code: 422
org.eclipse.basyx.vab.exception.provider.ResourceAlreadyExistsException: Could not create property.
In debug mode I can see that the getModelPropertyValue has successfully worked:
04:15:22.955 [main] INFO demonstration.Scenario2Connected - Current temperature: 20.0 Thank you for your time. Looking forward to hearing from you, Ahmed Osman |
