AjaxFormLoop with nested Ajax select onValueChange event

Hi everyone.

I'm developing a refine search component that need to add field's rows
dynamically, this rows contains 2 select components and by default a
textbox. When I change the value of the first select I have to update
the list of the second select and change the textbox to a component that
match with the data type of the first select eg. if I selected in the
first list a "String" type, the second select have to change options to
the ones that String types have and the textbox will remain, but if I
select a date type, the sencond select will change the options to the
ones that date type have and the textbox change to a dateField. I have
done this, but I have a problem when I add a new row, and I change the
older row data type, it will update the new's second list and textbox.
When I debug it, the zone injected i the java is the last one added and
not the one changed.

I really don't know if is right to mix this components. If someone need
the source code, just let me know and I will send it.

Tnx.

Luis
