Indeed..... so is that what it should be?
I used nested collections in the past without a problem. Why this time?

Probably returning a CollectionItem.

Hello,

Anyone ever had troubles with nested XSICollections?

I have this piece of code:




    var oModels = XSIFactory.createobject( "XSI.Collection" );
   
    var oObject, sObjectName, oModel, sModelName, oModelColl, oObjectColl, eModelColls, bNew, oGroup, sGroupName, i, iCount;
   
   
    // Enumerate selected objects
    for( var eSel = new Enumerator( selection ); !eSel.atEnd(); eSel.moveNext() )
    {
        oObject = eSel.item();
        sObjectName = oObject.name;
       
       
        // Check if object is a model
        if( oObject.type == siModelType )
        {
            //logmessages( '< ts_CreateCTRLGroup > :: Object "' + oObject.fullname + '" is a model, skipped.', siWarning );
        }
        else
        {
            oModel = oObject.model;
            sModelName = oModel.fullname;
           
            bExists = false;
           
            // Check if this model has been collected
            iCount = oModels.count;
           
            if( iCount < 1 )
            {
                // Create a new collection for this model
                oModelColl = XSIFactory.createobject( "XSI.Collection" );
               
                // Create collection where only the current object will be put
                oObjectColl = XSIFactory.createobject( "XSI.Collection" );
               
                oModelColl.items = oModel;
                oObjectColl.items = oObject;
               
                // Add the object collection after the model object, in the model collection
                oModelColl.add( oObjectColl );
               
                // Store this entire model collection in the main collection
                oModels.add( oModelColl );
            }
            else
            {
                bNew = true;
               
                // Enumerate the model collections
                for( eModelColls = new Enumerator( oModels ); !eModelColls.atEnd(); eModelColls.moveNext () )
                {
                    // Get single model collection
                    oModelColl = eModelColls.item();
                    logmessage( oModelColl.items );
                   
                   
                    if( oModelColl(0).fullname == sModelName )
                    {
                    }
                }
               
                if( bNew == true )
                {
                    // Create a new collection for this model
                    oModelColl = XSIFactory.createobject( "XSI.Collection" );
                   
                    // Create collection where only the current object will be put
                    oObjectColl = XSIFactory.createobject( "XSI.Collection" );
                   
                    oModelColl.items = oModel;
                    oObjectColl.items = oObject;
                   
                    // Add the object collection after the model object, in the model collection
                    oModelColl.add( oObjectColl );
                   
                    // Store this entire model collection in the main collection
                    oModels.add( oModelColl );
                }
            }
        }
    }




The problematic lines are marked with a // BIG PROBLEMS notation.
The first one, logmessage( oModelColl.items ); prints an empty string.
The second raises an error: //ERROR : Object not a collection - [line 78]

I would expect the line oModelColl = eModelColls.item() to return a XSICollection, but it seem not....


Any suggestion?



Thanks
