Not quite. The value of the "value" attribute is used directly. If you set it to "abc", then the text field will display "abc". So, you would probably use '<%= aString %>'.
If you have "indexed=true", that does the work of adding the brackets and array index to your resulting request parameter, you don't need to mangle the value yourself. You do have to make sure you have an indexed setter on your form bean that agrees with your resulting indexed request parameter name. This can get confusing, I know. -----Original Message----- From: Charlie Toohey [mailto:[EMAIL PROTECTED]] Sent: Friday, January 31, 2003 2:12 PM To: Struts Users Mailing List Subject: Re: html:text tag "indexed" attribute 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.
