Apply Template via Macro

Hello,

I m trying to Apply a Template via Macro in Aris.

this is the code :

for(m=1; m<=mod.length; m++){
if (mod[m]!=undefined){
   if(mod[m].getType()=="65548"){
   
   Designer.openModel(mod[m], false, false, true);
   var op=false;
   for(var o=0; o<=Designer.getOpenModels().length;o++){
   if(Designer.getOpenModels ( )[o]==mod[m]){op=true;}}
       
   if(op==false){Designer.openModel(mod[m], false, false, true);}
      
Designer.applyTemplate(mod[m], Designer.getTemplateByGUID ( "cec94fe0-9af8-11ed-7b48-005056c00008"), Designer.getOccs(mod[m]));   
   
Designer.save(mod[m]);
 Designer.closeModel(mod[m]);
}
}}

the template of the model gets changed by the code, but not the effect of the template (placing an attribute under the objects).

If i do it manually in architect; the effect takes place.

Thanks

Omar
