Another problem with logic:iterate
Hello,
this seems to be my day of problems. ;) Anyway, I have this code in my .jsp:
<logic:present name="fields">
<bean:define name="fields" scope="session" id="fields"
type="java.util.ArrayList"/>
<bean:define name="params" scope="session" id="fields"
type="java.util.ArrayList"/>
<logic:iterate id="f" name="fields">
<logic:iterate id="p" name="params">
<tr>
<td><bean:write name="f" property="value"/></td>
<td><bean:write name="p" property="value"/></td>
</tr>
</logic:iterate>
</logic:iterate>
</logic:present>
And I keep getting the following error:
Generated servlet error:
suchen$jsp.java:231: Variable 'fields' is already defined in this method.
java.util.ArrayList fields = null;
But I am not declaring that variable anywhere else in my .jsp... All I am
doing with fields is that I check if it is there and if it is I want to get
access to it, so I do a bean:define and read it from my session...
In case you want to see the whole .jsp here it comes:
<%@ page language="java" import="de.zmnh.user.User, java.util.Collection" %>
<%@ taglib uri="/struts-logic" prefix="logic" %>
<%@ taglib uri="/struts-tiles" prefix="tiles" %>
<%@ taglib uri="/struts-html" prefix="html" %>
<%@ taglib uri="/struts-bean" prefix="bean" %>
<font color="#CC0000" size="2" face="Arial, Helvetica,
sans-serif"><html:errors/></font>
<html:form action="/suchen">
<table width="75%" border="0" cellpadding="1" cellspacing="0"
bgcolor="#000066"> <tr>
<td>
<table width="100%" border="0" cellpadding="2" cellspacing="1">
<tr bgcolor="#FFFFFF">
<td colspan="4"><h3><font size="2" face="Arial, Helvetica,
sans-serif"><bean:message key="form.suchen.title"/></font></h3></td>
</tr>
<logic:present name="fields">
<bean:define name="fields" scope="session" id="fields"
type="java.util.ArrayList"/>
<bean:define name="params" scope="session" id="fields"
type="java.util.ArrayList"/>
<logic:iterate id="f" name="fields">
<logic:iterate id="p" name="params">
<tr>
<td><bean:write name="f" property="value"/></td>
<td><bean:write name="p" property="value"/></td>
</tr>
</logic:iterate>
</logic:iterate>
</logic:present>
<tr bgcolor="#FFFFFF">
<td colspan="2"><html:text property="field"/></td>
<td colspan="2"><html:text property="parameter"/></td>
</tr>
<tr bgcolor="#FFFFFF">
<td align="right"> </td>
<td align="right"><html:submit property="cancel"> <bean:message
key="form.suchen.button.cancel"/>
</html:submit></td>
<td align="right"><html:submit property="mehr"> <bean:message
key="form.suchen.button.mehr"/>
</html:submit></td>
<td align="right"><html:submit property="submit"> <bean:message
key="form.suchen.button.submit"/>
</html:submit></td>
</tr>
</table>
</td>
</tr>
</table>
</html:form>
What am I doing wrong?
Greetings,
Nadja
