RS01059: INTERNAL ERROR WHEN ACCESSING A TUPLE FIELD THAT IS A SET OR, ARRAY AND THAT TUPLE IS A SET ELEMENT RETRIEVED USING FIND/GET()

APAR status

• Closed as fixed if next.

Error description

• Example below where, a tuple is retrieved using find() leads to
  following error when the set field of tuple is accessed:
  ASSERTION FAILED at ../../../src/script/values.cpp:464 error
  
  tuple t{
   key int index;
   {int} order;
  }
  {t} T={<1,{1}>};
  execute{
   var x = T.find(1);
   //var x = Opl.item(T,0);//using this instead of find works
   var y = Opl.first(x.order);//Assertion Failed error
    //var y = Opl.item(x.order, 0);//Assertion Failed error
    /*
    for(var z in x.order){//workaround
       var y = z;
       break;
      }*/
      writeln("y="+y);
  }
  

Local fix

• Workaround:
  
  1) Opl.item is OK to be used if one knows the index of tuple
  item, but that may not be known at all times.
  
  2) Another alternative is iterating through various elements
  of tuple set, and stopping with the first one as below:
  
  for(var z in x.order){
       var y = z;
       break;
  }
  

Problem summary

• This issue has been resolved and fix will be available in CPLEX
  Optimization Studio v12.5.
