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

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
