ServiceTemplate Contains Two Top Nodes with PythonArchiveArtifact and WAR Upload

[LaviniaStiliadou]

Current Behavior:

When uploading a PythonArchiveArtifact and then a WAR to the service, the resulting ServiceTemplate contains two top nodes. This behavior is inconsistent with the expected behavior, as only one top node should be present in the ServiceTemplate.

Expected Behavior:

The ServiceTemplate should contain a single top node, regardless of whether a PythonArchiveArtifact is uploaded before a WAR or vice versa.

Steps to Reproduce:

1. Upload a PythonArchiveArtifact to the WF modeler-
2. Upload a WAR to the WF modeler.

Result:

The resulting ServiceTemplate contains two top nodes, which is not the expected behavior.
