Thanks very much Nick! It was indeed helpful. I was missing getter/setter
for individual list items!
now my form has following methods:
private String[] fruit = {"Apple", "Orange", "Banana"};
public List getFruits() {
return Arrays.asList(this.fruit);
}
public void setFruits(List l) {
this.fruit = (String[]) l.toArray();
}
public String getFruit(int index) {
if (this.fruit == null) return "null";
return this.fruit[index];
}
public void setFruit(int index, String f) {
this.fruit[index] = f;
}
my JSP has following has this html:iterator:
<logic:iterate name="theForm" property="fruits" id="oneF"
type="java.lang.String" >
<tr>
<td align="center">
hi!
</td>
<td>
<html:text property="fruit" name="oneF" indexed="true" />
</td>
</tr>
</logic:iterate>
and exception i get is this:
javax.servlet.jsp.JspException: No getter method for property fruit of bean
oneF
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:968)
i think it has to do with the fact that my individual fruit is a string
object rather than being a bean in itself if some getter method(s)?
can you see what's going wrong!
Thanks again.
