PM25104: Connectors on IBDs disappear after reloading the model

APAR status

• Closed as program error.

Error description

• 1.  Attached is a sample model in which replicates the problems
  we're seeing with disappearing connectors.
  2.    This model is a very simple car model with four wheels, an
  engine, and a drive train on the Model 1 BDD.
  3.    On the Top Level IBD a connector is created between the
  wheels (part with multiplicity of 4) and the drive train.
  4.    Four additional parts are defined on the Top Level Bdd
  each with a multiplicity of 1, typed with the Wheel block, to
  represent each wheel based on its position (front/back and
  left/right).
  5.    On the Detailed IBD each of these 4 wheel parts are placed
  on the diagram along with the engine and the drive train.
  6.    From the Layout menu a 'complete all relations' is done,
  and the connector defined earlier (connector_4) between the
  drive train and the itsWheel wheel part appears between Drive
  Train and one of the 4 wheel parts. This connector should not
  have been completed.
  7.    After saving, closing and reopening the model, then the
  model,  that connector disappears but is added back again when I
  do complete all relations.
  
  Our suspicion is that the connector is referenced to the Block
  port vs. the part port in the complete all relations action. But
  when re-rendering the drawing after a reopen the logic uses the
  part and not the block to draw it and thus removes it, or can't
  draw it. In this simple model it is easy to see and
  understanding. When you a drawing a more complex diagram in a
  model with many more connectors and use the complete all
  feature, from a user's point of view  it appears to be correct,
  because you do not want to reuse any existing connectors. Only
  to find out that some of your work is missing when the model is
  reloaded at a later point.
  
  Another important fact is this behavior is not seen if the model
  was created new in the 7.5.2.1 release. However, when a model is
  created in 7.5 and then the model is update to 7.5.2.1 this
  behavior is observed in both 7.5 and 7.5.2.1.

  Connectors on IBDs disappear after reloading the model
  

Problem conclusion

• The connectors will not be created anymore after complete
  relations.
