• Here is a brief description of what this PR does
  • Change unclear and generic warning messages in the logs into more explicit ones (especially for mapping issues)
  • Added a warning message when attempting to connect an item to a network port results in finding 0 or several ports
  • Fix a false positive warning when creating a network port without requesting it to be attached to a switch (considered as failed and triggered a warning)
  • Fix 2 issues regarding additional informations sharing a field name accross multiple itemtypes
    • they were overwritting eachother (i.e a Memory name overwritting a Processor name, or both having the same name...)
    • The data data injection form was only displaying the names of the fields, and not their itemtype (c.f screenshots)
      Unit tests to cover changes and ensure no regression
