Variable for a form value?

[Karl Beowulph]

Howdy all.

On my jsp page, I'm displaying a list of options from a database:

display.jsp

<html:form action="custOrder">
  <html:hidden property="action"/>
 
<table border = "1">
<tr><th>Date</th><th>Choice</th></tr>
<%
 
for (int i=0;i < custOrderBean.getDate().size() ;++i)
{
try
{
%><tr><td><%
out.print(custOrderBean.getDate().get(i));
%>
</td><td><html:radio property ="choice" value ="<% custOrderBean.getDate().get(i);%>" />
</td></tr>
<%
}
catch (IndexOutOfBoundsException e)
{
break;
}
}
%>
</table>
<html:submit property ="submit"/>
</html:form>

However, the value assigned to each radio button is literally the String "<% custOrderBean.getDate().get(i);%>".

Is there anyway for me to assign the String value of custOrderBean.getDate().get(i) into the radio buttons value?

Alright, I think I've solved it by using the following:

<html:select name = "custOrderBean" property = "date">
<%
 
for (int i=0;i < custOrderBean.getDate().size() ;++i)
{
try
{
%><option><%
out.print(custOrderBean.getDate().get(i));
%></option><%
}
catch (IndexOutOfBoundsException e)
{
break;
}
}
%>

It's not quite what I wanted, but it should suffice.

KB,
You had another question which mysteriously disappeared as I replied to it.

It had to do with phone entries and I assume you're using Struts.

My reply:
It is very possible. It'll be kind of tricky and you'll probably need to use a "map-backed" form. I put map-backed in quotes because I think you're better off using an ArrayList.

Here is an example:

<% int count = 0; %>
<logic:iterate id="idNotUsed" collection='<%= getMyListSomehow() %>'>
<html:text property='<%= "value(name" + count++ + ")" %>' />
<html:text property='<%= "value(addr" + count++ + ")" %>' />
<html:text property='<%= "value(phon" + count++ + ")" %>' />
</logic:iterate>

public void setValue(String key, Object value){
int count = Integer.parseInt(key.substring(4, key.length()-1));
String key = key.substring(0,4);
...
}
public Object getValue(String key){
int count = Integer.parseInt(key.substring(4, key.length()-1));
String key = key.substring(0,4);
...
return myList.getIndex(
}

Thanks, I deleted the question because I had read elsewhere that Struts wasn't designed to handle what I was asking for (a JSP script with the ability to create Forms) as all Forms are created when then JSP first loads.

Hi Mark,

I read the post by you regarding map backed forms. I am using map backed forms to generate a search criteria page dynamically. I could have <html:radio .. > as one of the elements on the JSP.

My problem is regarding prepopulation of the JSP page fields which uses map backed form. Is it possible to prepopulate th JSP when that JSP is genetated using map-backed forms?

Here is the code snippet I am using..

<c:when test="${queryForms.displayType == 'RadioButton'}">
<c:set var="displayTypeName" value="${queryForms.displayTypeName}"/>
<c:set var="displayValue" value="${queryForms.displayValue}"/>
<c:set var="delim" value=";"/>
<c:set var="buttonNameArray" value="${fn:split(displayTypeName, delim)}"/>
<c:set var="buttonValueArray" value="${fn:split(displayValue, delim)}"/>
<c:forEach begin="0" end="${fn:length(buttonNameArray) - 1}" var="token">
<html:radio property="param(${queryForms.paramName})" value="${buttonValueArray[token]}"/>${buttonNameArray[token]}   
</c:forEach>
</c:when>

Please let me know if anybody has idea about this.

Thanks,
Archana.
