Another bean:iterate question

["Brett G. Palmer" <pb...@qwest.net>]

I've been working on this <bean:iterate ... > problem for some time now.  I
finally had to use a scriplet to get it to work.  I am trying to get a list
of FieldTypes from a record controller (PrimaryServer below) which implement
an AbstractField object (this may be the entire problem ... let me know if
Abstract objects will cause problems).  The controller has a method called
getFieldList which returns an Iterator of these AbstractField objects.  I
then want to get the name of each field using the property getFielName().
The following is a snippet of my Jsp page.  Tomcat always returns with an
error saying it "can't find bean 'field' in scope null".

<logic:iterate id="field" name="PrimaryServer" property="fieldList"
type="com.iic.dbsync.IntField">
  <tr>
    <td align="center"> <jsp:getProperty name="PrimaryServer"
property="fieldList"/>
              <bean:write name="field" property="fielName"/> </td>
    <td> <html:text property="field2" size="100"  /></td>
  </tr>
</logic:iterate>

Here is the scriplet that I wrote to finally get the results that I wanted.


<% Iterator iter = PrimaryServer.getFieldList();
    while( iter.hasNext() ) {
        AbstractField field = (AbstractField) iter.next();
        String fieldName = field.getFieldName();
%>
  <tr>
    <td align="center"> <%=fieldName%> </td>
    <td> <html:text property="field2" size="100" /></td>
  </tr>
<%    }
%>

The iterator tag still trips me up from time to time.  If anyone has any
suggestions I would appreciate them.  I have enjoyed reading the previous
postings concerning the iterator tag.

Thanks again,

Brett

<html:radio property="fd" value="aValue"/>

Your form bean must have a property "fd". If the value of this property is equals to "aValue" the button will be
checked.

This is done by checking the value of your radio tag and the value returned by your getter method.

e.g if you have

 <html:radio property='xxx'  value="1" />
 <html:radio property="xxx" value="2" />

if the getXxx method returns "2" the second radio button will be selected.

I've received that error before when I forgot to include the taglib
directive for the logic library.  That would prevent the "field" bean
from being created and result in the error you're seeing.
