SDK: Read data property via script contribution

Hi there,

I'm trying something quite simple, but can't get it work.

I got a component which is data bounnd.

That compoment has a property named "data" type "ResultSet". (I dont post the XML-part here since everybody should know how it looks like).

In component.js I set the data like that:

   this.data = function(value) {      if (value === undefined) {         return data;      } else {         data = value;         console.log('data has been set',data);         return this;      }   };

Now, I would like to read the data property as a string.

In contribution.ztl I have the following function:

   /* Get data as String */   String getDataAsString() {*      return JSON.stringify(this.data);   *}

But this method allways returns an empty string.

I'm sure the data property is not empty, since I can see the data object in the console output.

Do I make an obvious mistake?

Thanks,

ben
