Wrong user name saved when using nuxeo-user-suggestion and Empty Doc Created



    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Won't Fix
    • Affects Version/s: None
    • Fix Version/s: None
    • Component/s: UI


      Problem: When a nuxeo-user-suggestion is pre-filled with a user (value set in the Empty Document Created event), the value saved is prefixed with user: if the current user does not change the preset value. If the dropdown i used, then the value is saved with no prefix.

      Reproduce: targuillere-SANDBOX, branch feature/test-preassignment tested with 10.10HF04

      • MyDoc has 2 fields, owner, type User/Group and owner_received, string
      • Listener on Empty Document Created set mydoc:owner to the current user
      • Listener on About to Create set the value of mydoc:owner_received to the value of mydoc:owner (this is done to quickly see the result. Same would be done with looking at the JSON)
      • Run a server (10.10HF04), login as Administrator/Administrator, deploy the project, create a workspace
      • Create a new MyDoc, fill only the title, let the default value for owner, save => user saved is prefixed user:Administrator
      • Back to the workspace, create a new MyDoc, this time, remove the user set by default and reselect it in the dropdown, save => user saved is correct Administrator

      Note: In the layout, see that the "Prefixed" property is not checked.

      Workaround: In "about to create", detect the prefix is there and remove it.

      ======== Second test, showing the pain server side.
      Other test that shows it breaks server side.

      There is a "Document Created" event, MyDoc_DocCreated, that calls the MyDoc_DocCreated chain:

      • Only if the title is "TestAddPermission"
      • The chain calls Document.AddPermission to give "Everything" to the user set as medic:owner


      • Login as Administrator
      • Create a Workspace, say "ws"
      • Change permissions: Add "ReadWrite" for "members"
      • In a private window (or just logout) login as johni/johni (this user is in the U&G of Studio and creation policy is "Always")
      • Navigate to "ws"
      • Create a new MyDoc
      • Do not change the default "owner"
      • just set a title to "TestAddPermission "
      • Click "Create"

      => Error: The following set of User or Group names do not exist: [user:johni]

      2019-04-12T10:28:56,981 ERROR [http-nio-] [org.nuxeo.ecm.automation.core.events.OperationEventListener] Failed to handle event documentCreated using chain: MyDoc_DocCreated
      org.nuxeo.ecm.webengine.model.exceptions.IllegalParameterException: Failed to invoke operation Document.AddPermission with aliases [Document.AddACL], The following set of User or Group names do not exist: [user:johni]. Please provide valid ones.
      	at org.nuxeo.ecm.automation.core.operations.document.AddPermission.validateParameters(AddPermission.java:186) ~[nuxeo-automation-core-10.10-HF04.jar:?]

      This error happens because the value set in the field by WebUI is prefixed in this case (not changing the value set by default)
