Improper syntax generated in projects handling complex data

In the context of NXP-28557 and associated project,
Current Studio generated code

        <fields>
          <field>data['gs1scm']['certification']['0']['certifAgency']</field>
        </fields>

is to working anymore and must be replaced e.g. with the following syntax:

data.gs1scm.certification[0]["certifAgency"]

namely the entry should be numbered 0 and not '0'
