How to resolve "org.rythmengine.exception.CompileException: Duplicate parameter e"

[Swati Raina]

Hi, 

I am new to rythm and cant seem to find enough documentation to read through s posting the Questions here.

My template looks like this:

@args String subTitle
@args String title
@args String description
@args String locale
@args java.util.List<String> pictureURL
@args java.util.Map<String,Object> itemSpecifics
@args String productIds
@args Integer order

{
   "localizedProductDetails":[
      {
         "subTitle":"@subTitle",
         "title":"@title",
         "description":"@description",
         "locale":"@locale",

         @if(itemSpecifics != null) {

            "attributes":{

                @for( Map.Entry<String,Object> e: itemSpecifics.entrySet()){
                    "@(e.getKey())" : @(e.getValue()) ,
                }

            }

         }
      }

   ],

   @if(pictureURL != null){

    "pictures":[ {

      @for( String pic : pictureURL ){
            "order":"@(order+1)",
            "pictureURL":"@pic"
      }
    }
   ]
   ,
   }


}

and then i pass the hashmap of values to be populated.

But i get compile issue: 

org.rythmengine.exception.CompileException: Duplicate parameter e

Can someone please guide?

Try to avoid use "e" as your variable name, obviously rythm in that version is using it as the name of the RuntimeException.
