Subject Re: Some JSP Taglib help needed
Date Tue, 01 Aug 2006 16:45:37 GMT
You could try something like:

<html:form action="....>
<c:foreach begin='0' end='${endval}' varStatus='idx'>
  <html-el:text property='student_name_${idx.count}'/>

But, why not make the student_name an array? The code below should
work, I havent' compiled it and I usually iterate thru a list of beans
not scalar Strings, but it should be close.
- Declare the element in the formbean as <form-property
name="student_name" type="java.util.List"/> or create student_name as
a java.util.List if using a POJO for an ActionForm
- Create a setup action that is called before the JSP is initially
rendered which  does a '((MyFormType)form).student_name = new
- In the JSP form:
<html:form action="...>
<c:foreach begin='0' end='${endval}' varStatus='idx'>
  <html-el:text property="student_name[${idx.index}]"/>
