Problems with loadbatchactions

Hi people, I'm delphi developer, I'm working with delphi 2005 and I've one problem, when I try to load a .srf file, the file is loaded in a little and simple app, but don't work on real app, delphi wait for the answer and SBO don't response.

example :

var

FoSboGuiApi : SAPbouiCOM.SboGuiApi;

FoSboApp : SAPbouiCOM.Application;

.....

.....

begin

........

........

........

FoSboGuiApi := SAPbouiCOM.SboGuiApiClass.create();

FoSboGuiApi.connect(sCon);

FoSboApp:= FoSboGuiApi.GetApplication(-1);

//add menus options

......

......

......

//load form

oSboXMLDocument := XMLDocument.Create();

oSboXMLDocument.Load('C:\file.srf');

oSboXMLDocument.SelectSingleNode('/Application/forms/action/form/@uid').Value := sFrmUid; // the simple app have too this line

sXmlStr := oSboXMLDocument.InnerXml;

FoSboApp.LoadBatchActions(sXmlStr); //in this line the complier wait for SBO process but SBO never response or never return

//I try too this : FoSboGuiApi.GetApplication(-1).loadBatchActions(sXmlStr);

//but the result is same

end;

the little app has the same source code, but work good
