Positioning subform choice sets disregarding of data occurrence order.

Hi, I'm facing an issue,

let say I have the following subform structure (simplified):

- subform set

   - form A (Checking)

   - form B (Saving)

    - form C (Credit Card)

Now, the subform set is a choice subform set, in the alternatives expression panel I have something like this:

form A: productCategory == "Checking";

form B: productCategory == "Saving";

form C: productCategory == "Credit Card";

And this is my (simplified) xml data:

<root>

    <account>

        <prodcutCategory>"Saving"<prodcutCategory>

        <productName>"Saving Account 2.0"<productName>

        <statuts>"Active"<statuts>

    </account>

    <account>

        <prodcutCategory>"Credit Card"<prodcutCategory>

        <productName>"Mastercard"<productName>

        <statuts>"Inactive"<statuts>

    </account>

    <account>

        <prodcutCategory>"Checking"<prodcutCategory>

        <productName>"Checking Account Plus"<productName>

        <statuts>"Active"<statuts>

    </account>

</root>

As you can see, the order in wich the data elements appear is not the same as the order I have my hierarchy formed. This results in having my hierarchy following the data order, and not the order I set in the first place, which I think it's a normal behavior.

However, I need to follow my hierarchy, disregarding the data ocurrence order.

I've tried to find some sort of index attribute in the subforms (there is actually an "index" attribute, but I couldn't work with it), but I had no luck.

If anyone knows how to achieve this, I'd appreciate it!.

Thanks.
