CTRL-script: Working with struct having a mapping - direct access to mapping not working, DebugN() does not list content of mapping

[kwiesinger]

I have performed some tests if the CTRL-script can cope with c-structs having a mapping.

It seems, that basically c-structs are supported, but I've notices two issues:

1. Direct mapping manipulation via the struct-data is not working and causes an exception.
2. DebugN() does list the (primitive) data of the struct, but not the mapping content.

WinCC OA version: 3.14 64bit
Patches: P5
operating system: Windows7 64bit

Here is my test example:

Code: Select all

struct SStructData
{
  string   strAction;
  uint     uState;
  mapping  mDps;
};

struct SDpData
{
  string strName;
  string strType;
};

void main()
{
  SDpData myDp;
  myDp.strName = "NameX";
  myDp.strType = "TypeY";
  DebugTN( __LINE__ +" myDp:" );
  DebugN( myDp );
  
  SStructData myStructData;
  myStructData.strAction = "ON";
  myStructData.uState = 1;
  DebugTN( __LINE__ +" myStructData:" );
  DebugN( myStructData );
  DebugTN( __LINE__ +" myStructData.mDps:" );
  DebugN( myStructData.mDps );
  
  // Direct manipulation - not working
  try
  {
    myStructData.mDps[ myDp.strName ] = myDp;
  }
  catch
  {
    DebugN(getLastException());     
    DebugN(getErrorStackTrace(getLastException()));
  }
  DebugTN( __LINE__ +" myStructData:" );
  DebugN( myStructData );
  DebugTN( __LINE__ +" myStructData.mDps:" );
  DebugN( myStructData.mDps );
  
  // Indirect manipulation - working
  {
    mapping myMapTemp = myStructData.mDps;
    myMapTemp[ myDp.strName ] = myDp;
    myStructData.mDps = myMapTemp;
  }
  DebugTN( __LINE__ +" myStructData:" );
  // DebugN() at the struct does NOT list the content of the mapping
  DebugN( myStructData );
  DebugTN( __LINE__ +" myStructData.mDps:" );
  DebugN( myStructData.mDps );
}

And here the console output:

ad 1: this is currently not implemented
ad 2: seems to be a bug in 3.14 which is already solved in 3.15 (note that struct/class are an experimental feature in 3.14)
