Thanks. I hope somebody knows the answer to the first question. re: my iterate over String array question --- I've got half of a solution, i.e. to pre-populate the form by supplying the "value" attribute. The other half is producing HTML input text tags with "name" attributes aString[0], aString[1],... so the form bean will be populated on submit. I assume that I would do the exact same thing you suggested for the value tag in the property tag, i.e. <html:text indexed="true" name="aBean" property='<%="aString[" + GET_INDEX + "]"%>' value= '<%="aString[" + GET_INDEX + "]"%>' />
So, the "property" and "value" attributes would have identical values ? However, this seems wrong, because based on your document, my HTML name would evaluate to "aBean.[nn].aString[nn], rather than aString[nn] Also, I still don't know where to get the index that I would put in GET_INDEX above ? Obviously I'm pretty lost here --- as I said, I can only find examples/discussions in the mailing archive with collections of beans, but nothing with collections of Strings, which is what I'm trying to do.
