<p>is there an easy way to solve the following problem.</p>

<p>Let's say I fetch a IList with some books in my controller from my model. Now I want to enrich the output and fetch a preview from Amazon with another model from an outside framework and get another IList.</p>

<p>Now I put both ILists into a property bag.</p>

<p>In NVelocity I use a #foreach for the BookList, but how can I access the amazonbooklist with the right preview? 
I cannot use $amazonbook[index], where index would be the isbn.
Do I really need to put both lists in one big list with a simple onject containing only the two other objects?</p>

<p>Remember, both models are from different frameworks and cannot be placed in one framework. Both frameworks have to stay seperated. I try to solve the NVelocity problem and ofcourse, this problem is just an example, we don't sell books ;)</p>

There may be a simpler solution, but I would create a third class like such
```
```
class BookList{
       MyBookObject     a;
       AmazonBookObject b;
}
```
```
a list of this third class could be passed to your view at once.
