Hi to all.
I have a problem with a logic:iterate tag. I'm using Struts 1.3.
I have to populate a select with data read from db (by invoking the first
Action). When a select option is selected in the jsp, I have to invoke a
second Action (on the same jsp page) which has to perform some operations

Hello Chad, hello Yoge,
thanks for your hints!
meanwhile, I could find a third solution:
Another solution should be to use EL:
But this solution doesn't work for me (the string ${object.rows} appears
unchanged after rows=) , though I'm using tomcat 5.5 and struts 1.2.9..
May be,
Another way to do it (with a little bit less java) is:
