Error description

• Hi,
  
  
  
     I am using Rational Software Architect v8.5.1 with BIRT
  
     reporting following the instructions here
  
  
  
     [1]
  http://www-01.ibm.com/support/knowledgecenter/SS5JSH_9.1.1
  
     /com.ibm.ccl.erf.doc/topics/t_create_report_specifics.html
  
  
  
     Specifically using the following to list all the component
  in
     a diagram.
  
  
  
     For a class diagram, a list of classes that are in the
  
     diagram
  
  
  
     Create a UML data set with the following characteristics:
  
       * Parameter: diagram
  
       * Row Mapping:
  
            + Expression: oclEvaluate(resolveURI($diagram),
  
  
  "self.children->select(c|c.element.oclIsKindOf(uml::
              Class))->collect(c|c.element)")
  
            + Type: uml:Class
  
  
  
     When you use the data set in a report design, set the
  
     parameter value to the URI of a diagram in the model.
  
  
  
     When I run the report or preview the data I get the
  following
     error.  I have narrowed this down to happen only when there
  
     is a Geometric shape (eg. A rectangle) in the diagram.  If
  
     there are only UML modelling elements in the diagram it
  works
     fine.  I suspect this is something to do with the rectangle
  
     coming from the GMF Notation package rather than the UML
  
     package, but cannot work out how to resolve the issue.

Local fix

• You can use the following OCL expression to fix the issue and
  still get
  the elements of type UML:Component in their OCL Query:
  ===========================================================
  oclEvaluate(resolveURI("platform:/resource/TempErrorModel/T.emx#
  _04CJYKn
  WEeWCJ6SMXVuo0w"),
    "self.children
      ->
         select(e|e.element.oclIsKindOf(uml::Component))
         ->reject (e|e.element = null)
       ->
         collect(e|e.element)"
    )
  ===========================================================
  
  The problem is with the Geometric shapes added in to the
  returned
  collection of Components (that too as "null" objects).
  
  You can use the above expression as a workaround to get the UML
  Component elements collection by rejecting the null elements
  from the
  returned collection in the "select" expression.

Problem conclusion

• Birt Report Generation with geometric shapes on the diagram was
  throwing an internal error thereby not generated the correct
  report. This is because, ocl query for picking up the UML
  elements was returning a null object in the result though the
  geometric shape was not an UML element.
  
  With this fix this issue is fixed and Birt report generation
  will work as expected though there are geometric shapes on the
  diagram/model.
