Hello

I have a problem using the command kSetDocNameCmdBoss. The way I use it crashes ID.

I've created a snippet setDocName that runs the following code:
ErrorCode SnpSetDocName::SetDocName(void)

#include "DocumentID.h"

{
	ErrorCode result = kFailure;
	PMString nameString("newName");
	do {
		InterfacePtr<ICommand> cmd( CmdUtils::CreateCommand( kSetDocNameCmdBoss ) ) ;
		InterfacePtr<IStringData> cmdString( cmd, IID_ISTRINGDATA ) ;
		if ( cmd )
		{
			IDocument* doc = Utils<ILayoutUtils>()->GetFrontDocument();
			cmd->SetItemList( UIDList( doc->GetDocWorkSpace() ) );

			cmdString->Set( nameString ) ;
			// About to use nil interface ptr!
			result = CmdUtils::ProcessCommand(cmd);
		}
	} while(false);
	return result;
}

ID crashes on ProcessCommand(). The debug log says "About to use nil interface ptr!" when ProcessCommand is executed. Which pointer is nil?

Thanks for help?
