Indexed Property and Hand Cranking Lazy List
Hello all, I am sorry to subject this list to yet another person who doesn't
understand something, but I can't for the life of me figure out hand
cranking lazy lists.
I am using 1.2.9 with java 1.5.0_06 And I can't get lazy lists to work.
I am trying to use what I found at :
http://wiki.apache.org/struts/StrutsCatalogLazyList
And as such have :
In the ProdSelectionFrom:
private List skills = new ArrayList();
public List getSkills() {
return skills;
}
// non-bean version so as not to confuse struts.
public void populateSkills(List skills) {
this.skills.addAll(skills);
}
public void setSkills(Product skill) {
this.skills.add(skill);
}
public Product getSkills(int index) {
// automatically grow List size
while (index >= skills.size()) {
skills.add(new Product());
}
return (Product)skills.get(index);
}
In the JSP:
<logic:iterate name="ProdSelectionForm" property="skills" id="skills">
<tr>
<td>
<html:text name="skills" property="skillId"
indexed="true"/>
</td>
</tr>
</logic:iterate>
And can't even get this to display properly.
I am getting the error message:
No getter method for property: "skills" of bean: "ProdSelectionForm"
javax.servlet.ServletException: javax.servlet.jsp.JspException: No
getter method for property: "skills" of bean: "ProdSelectionForm"
Could someone please point me in the right direction as I am at my wits end
on this.
The entire point of what I am trying to do is to be able to post a list of
information about a product (such as description, number, price etc) and
allow the user to edit the number and have them submit the form so that I
can update a database with a new order.
I am using a product Object which has all of the characteristics mentioned
before as well as others, and each of them have publically available getter
and setter methods.
I would also like to confirm that the comment I read that I should be using
strictly strings when dealing with the jsp is correct - can someone confirm
that ?
Also is there a problem using ArrayList over List ?
Thanks so much for any thoughts/ time you can give me.

I'm just saying I'm not too confident about the example you followed.
If I had the time right now, I'd test it in a sample app just to see
if it would work. Your message seems to say it doesn't, though.
Try modifying the form so that getter and setter return and accept a
List. And for your other question, the answer is yes, indexed or not,
<html:text> should be referring to string properties.

I had modified it after you are correct, I am trying to get it to fit in
with my work.
Hubert are you suggesting what I am trying to do will not work in the manner
I am trying to do it ?
thanks in advance

Struts is getting confused by:

> }
The getter and setter should be consistent.

Hmm... I just looked at the link you sent and it looks like your code
was modelled after that. I've never done it that way, and I would not
have expected it to work. What I've done in the past is much closer
to the examples under the "Using Commons Collections for lazy Lists"
section, where the getter and setter return and accept the same type.
