I'm trying to set the offset to a bean value which acts like a counter ...

Basically what i want to do is:

<logic:iterate id="firstElement" name="firstList">

<logic:iterate id="secondElement" name="secondList" offset="????"
length="1">

...

</logic:iterate>

</logic:iterate>

where the offset is the current offset of firstElement ...

any ideas?

The iterate tag has 'offset' and 'length' as
attributes.  You should be able to use both of these
to retrieve a specific element.

http://jakarta.apache.org/struts/struts-logic.html#iterate

length - The maximum number of entries (from the
underlying collection) to be iterated through on this
page. This can be either an integer that directly
expresses the desired value, or the name of a JSP bean
(in any scope) of type java.lang.Integer that defines
the desired value. If not present, there will be no
limit on the number of iterations performed.
[RT Expr]  

offset - The zero-relative index of the starting point
at which entries from the underlying collection will
be iterated through. This can be either an integer
that directly expresses the desired value, or the name
of a JSP bean (in any scope) of type java.lang.Integer
that defines the desired value. If not present, zero
is assumed (meaning that the collection will be
iterated from the beginning.
