Hi Nicolas,
After some reading, I wrote the following code that works pretty well...
<logic:iterate name="objA" property="hTable" id="objB" >
Next element is <bean:write name="objB" property="value.prop" />
[<bean:write name="objB" property="key" />]
</logic:iterate>
I don't fully understand how the cast from Object to ObjB is performed but
it works....
Thanks for your help.
