How to iterate over two (or more) collections simultaneously ?

[Pascal Jacob]

Hi again,

Is it possible to iterate over two (or more) collections SIMULTANEOUSLY 
using the same indice ?

Here is a example:

   <parameterMap id="create-data-table-param" class="java.util.HashMap">
       <parameter property="names" javaType="string" /> <!-- really an 
array of string -->
       <parameter property="types" javaType="string" /> <!-- really an 
array of string -->
   </parameterMap>
   
   <statement id="create-data-table" 
parameterMap="create-data-table-param">
       CREATE TABLE data
           <!-- what would be the name to set in the property attribute 
? -->
           <iterate property="???" open="(" close=")" conjunction=",">
               <!-- I want the names and types collections to be 
iterated in synch -->
               $names[]$ $types[]$
           </iterate>
   </statement>

Nested iterate statements won't do it because it produce n*n outputs 
instead of just n (n is the number of elements in the collections).

Any help would be appreciated.
