Hello,
I have been using:
elem = CapellaElement(CapellaPlatform.getFirstSelectedElement())
to select elements from a diagram.
The problem is that when the element is selected directly in the project explorer, everything works fine, but when the item is selected from a diagram then I would obtain a graphical element/class from Sirius (such as DNode… etc)
Let’s take the examples of both instances for this code:
elem = CapellaElement(CapellaPlatform.getFirstSelectedElement())
print(elem)
print(type(elem))
print(elem.get_id())
print("Test")
print("End of Script")
In both instances the type is “<main.CapellaElement object at 0x00000SomeNumberAdress>”, however their eclass is different (which is displayed only for the actual item, the node has no attribute/fonction for eclass).
When selectring from the diagram, then the item is a node, therefore our script code will naturally produce errors (You cannot get an “id” from a Node I believe, a Node is not an abstract element). The problem will be resolved if the graphical item is replaced with its targeted capella item.
When searching I found a function that gets the target for a diagram object. Click to expand:

I tried to apply it but failed, I wrote comments next to each line of code, to show the type of error I got:
elem = CapellaElement(CapellaPlatform.getFirstSelectedElement())
print(elem) #<__main__.CapellaElement object at 0x0000021B829CAD08>
print(elem.get_java_object()) # DNodeListEditPart( org.eclipse.gmf.runtime.notation.impl.NodeImp ...
#print(elem.get_java_object().target) #<py4j.java_gateway.JavaMember object at 0x0000021B829D0108>
#print(elem.get_java_object().get_target()) # Method get_target([]) does not exist
print(elem.get_target()) # AttributeError: 'CapellaElement' object has no attribute 'get_target'
print(elem.target) # AttributeError: 'CapellaElement' object has no attribute 'target'
print(type(elem))
print(elem.get_id())
print("Test")
print("End of Script")
I failed to obtain the targeted item using the following:
- .get_java_object().target
- .get_java_object().get_target()
- .get_target()
- .target
What am I missing? How can I obtain the actual target? Thank you.
Edit: I also tried the getTarget():
#print(elem.get_java_object().getTarget())
print(elem.getTarget())
→ AttributeError: ‘CapellaElement’ object has no attribute 'getTarget’
