As I understand the implementation of html:select, I would have to return a
collection of something. Collection of beans? One of my select lists has
370 school names in it. The last thing I want to do is to create/pass
around a collection of 370 objects instead of one StringBuffer (actually
converted to String at the end of the tag class).
If there's another way to use html:select as I have used the tag, please let
me know. Plus, how is it a breach? Doesn't struts use custom tags? Why
can't I use a combo of struts and my own tags?
I actually have to do a repost with this page too so I even use a usebean
tag along with my struts form tag at the top so that I can have a selected
option. Basically the user picks a school name and the form reloads with
the school's address filled in for the user.
Suggestions welcome.
Here's my code snipet:
<jsp:useBean id="schoolAddressForm"
class="edu.cccs.energizer.SchoolAddressForm" scope="session"/>
<html:form name="schoolAddressForm"
type="edu.cccs.energizer.SchoolAddressForm" action="forms/schoolSave.do" >
....
<select name="suffix" onChange="getAddress();">
<%
//only select it if it exists
String suffix = "";
suffix = schoolAddressForm.getSuffix();
if (suffix != null)
{
if (suffix.length() > 0)
{
%>
<option value="<%= suffix %>" SELECTED><%= schoolAddressForm.getName()
%></option>
<option value="">--------------------------</option>
<option value="">Select One Below:</option>
<% }
} else {
%>
<option value="" SELECTED>Select One Below:</option>
<% } %>
<ene:optionlist
sql="SELECT school_suffix, name FROM schools ORDER BY name"
value="school_suffix"
item="name" />
</select>
