Description

STR

1. Let's say the user has CAPACITY-SCHEDULER view instance with /main/view/CAPACITY-SCHEDULER/auto_cs_instance short URL set
2. Clone this instance or create another CAPACITY-SCHEDULER instance manually
3. Set the same short URL as for the first instance

Result

• If 'Name' property is the same, request for adding new URL fails
  request:

  POST api/v1/view/urls/auto_cs_instance
  
  {
      "ViewUrlInfo": {
          "url_name": "auto_cs_instance",
          "url_suffix": "auto_cs_instance",
          "view_instance_version": "1.0.0",
          "view_instance_name": "AUTO_CS_INSTANCE_Copy",
          "view_instance_common_name": "CAPACITY-SCHEDULER"
      }
  }
  

  response:

  {
    "status" : 500,
    "message" : "An internal system exception occurred: This view URL name exists, URL names should be unique"
  }
  

• If name is different, the REST call succeeds even if URL itself is duplicate:

  POST api/v1/view/urls/auto_cs_instance1
  
  {
      "ViewUrlInfo": {
          "url_name": "auto_cs_instance1",
          "url_suffix": "auto_cs_instance",
          "view_instance_version": "1.0.0",
          "view_instance_name": "AUTO_CS_INSTANCE_Copy",
          "view_instance_common_name": "CAPACITY-SCHEDULER"
      }
  }
  

  response is 201 in this case; URL is created

• As result there are two view instances with the same URL, and the first one is no longer accessible by this URL
