PM23701: error raised tracing to child requirement

APAR status

• Closed as program error.

Error description

• STEPS TO REPRODUCE
  the projects A and B are externaly connected
  the projects A and B are stored in a DB2 database
  
  actions in project B
  - create a requirement NONE1 ( of any requirement type *)
  - create a child requirement NONE1.1 for NONE1
  
  actions in project A
  - create a requirement NONE1 ( of any requirement type *)
  - create a trace from a.NONE1 to B.NONE1.1
  - close the properties of NONE1
  - open the properties of NONE1
  - open the TAB Traceability of requirement NONE1
  - open the properties of B.NONE1.1 by dubble click on B.NONE1.1
  - close the properties of B.NONE1.1
  - close the properties of NONE1
  - open the properties of NONE1
  
        ==? Runtime Error 'cachedPermissions' not understood
  (screenshot error DB2)
  
  - close errormessage
  - open the properties of NONE1
  
        ==? RuntimeError: Objektvariable oder With-Blockvariable
  nicht festgelegt (could not reproduce this 2nd errormessage)
  
  
  if both projects A and B are stored in an ACCESS database, the
  errormessage is different:
  
        ==? Unable to retrieve the package from the server.
  Reason: You must use the GetRootPackage function to retrieve the
  RootPackage object. (screenshot error ACCESS)
  
  - close the errormessage
  
        ==? RuntimeError: Receiver is not a boolean ( screenshot
  error access 2) is showing directly after closing first
  errormessage
  
  
  * make sure the requirement types used are enabled for external
  traceability!

  When trying to display the Requirement Properties dialog, it
  might result in an error.  This only happens if such
  requirement has a traceability relation to/from an external
  requirement and that external requirement is a child.  The
  Requirement Properties dialog does not opens and an error
  message is displayed instead.
  
  The error received might be one of these:
  - Runtime error: "cachedPermissions" not understood
  - Runtime error: receiver is not a Boolean
  - Unable to retrieve the package from the server.  Reason:
  You must use the GetRootPackage function to retrieve the
  RootPackage object.
  

Problem conclusion

• When displaying the Requirement Properties dialog for an
  external requirement, it is always in read-only mode.  A
  logic was added to properly verify package permissions if
  the requirement is external.
