How to get and set an object style to page item

[Stefano5C37]

Hi everyone,
I was autoflowing an overset page item programmatically, but noticed that autoflowing doesn't apply the ObjectStyle of the overset page item.
So I thought I'd iterate through all the boxes created by AutoFlow and give them an object name and style.
On the name no problem, but as regards the object style I have some problems.
I have no idea how to get and how to give a box an object style.

I've tried something like this, but was unsuccessful.

InterfacePtr<ICommand> applyObjectStyleCmd(CmdUtils::CreateCommand(kApplyObjectStyleCmdBoss));
        if(!applyObjectStyleCmd)
            break;
        applyObjectStyleCmd->SetItemList(listOfPageItemToApplyObjectStyle);

        InterfacePtr<IUIDData> UIDData(applyObjectStyleCmd, UseDefaultIID());
        if(!UIDData)
            break;
        UIDData->Set(DATABASE, UIDStyle);

        if(CmdUtils::ProcessCommand(applyObjectStyleCmd) != kSuccess)
            break;

listOfPageItemToApplyObjectStyle --> rapresent all the page item created by autoflow

UIDStyle --> rapresent the style that i want to appy to boxes, I set it simply by looking for it by name, but I would like the page item to be overset

This is my solution:

/// GET Object Style from pageItemA and SET to pageItemB
ErrorCode function(UIDRef pageItem_A, UIDRef pageItem_B)
{
    ErrorCode result = kFailure;
    
    do
    {
        // ----- GET OBJECT STYLE -----
        InterfacePtr<IGraphicFrameData> graphicFrameData_A(pageItem_A, UseDefaultIID());
        if(!graphicFrameData_A)
            break;
        
        /// UIDStyle Of pageItemA
        InterfacePtr<IPersistUIDData> persistUIDData(graphicFrameData_A, IID_IPERSISTOBJECTSTYLEDATA);
        if(!persistUIDData)
            break;
        
        UID UIDStyle = persistUIDData->GetUID();
        if(UIDStyle == kInvalidUID)
            break;
        
        
        
        // ----- SET OBJECT STYLE -----
        InterfacePtr<IGraphicFrameData> graphicFrameData_B(pageItem_B, UseDefaultIID());
        if(!graphicFrameData_B)
            break;
        
        /// UIDListOfPageItemToApplyObjStyle: List fill of UID of PageItem belonging to kSplineItemBoss, otherwise ApplyObjectStyleToUIDList don't apply the ObjectStyle
        UIDList UIDListOfPageItemToApplyObjStyle;
        UIDListOfPageItemToApplyObjStyle.push_back(GetUID(graphicFrameData_B));
        
        /// I haven't clue of how use categoriesToOverride, so i left it empty and it works anyway
        K2Vector<ClassID> categoriesToOverride;
        categoriesToOverride.push_back(kInvalidClass);
        result = Utils<Facade::IObjectStylesFacade>()->ApplyObjectStyleToUIDList(UIDListOfPageItemToApplyObjStyle, CONTEXT->GetContextWorkspace(), UIDStyle, categoriesToOverride, false);
        
    }while(false);
    
    return result;
}

If anyone has more elegant solutions feel free to share it.
