Re: A table on a form from a List of Lists

[Olasoji Ajayi]

the method did not work, i think its because the nested tags deal with beans 
nested in beans but this deals with lists in a list in a bean (like a 2 
dimensional array), i was hoping if i code the property like 
property[row][col], if will call my getter method String getProperty(int 
row, int col) since it calls String getProperty(int index) for property 
specified as property[index].
all the methods i have used either comes up with the erron no gettter method 
for this or that or null attribute.

i am begining to think there is no way to get/set a two dimentional array 
type of data in a form bean other than to make the property also beans.

i would really appreciate any help because i want to keep my property as a 
list of lists. the form bean is like:

public class myBean extends ActionForm{
 private List table = new ArrayList();
/// other propeties that are of type string
public List getTable(){
 return table;
}
public List getRow(int row){
 return (List)table.get(row);
}
public String getField(int row, int col){
 return (String)((List)table.get(row)).get(col);
}
//// and corresponding setter methods
i wrote the acessor methods this way so i can specify different property to 
get different componentof the bean's property.

the problem i have is how to code a jsp to call the getter/setter methods 
with two int arguments, i dont know very much about the bean specification. 
can anyone tell me how to code my jsp or ActionForm to get the third 
accessor methods called, to populate an html:text or set the ActionForm 
property from html:text

Take a look at the nested tags.
In your case, your code may end up looking like:
<nested:form action="/myAction">
<table>
 <nested:iterate property="listOfRows">
 <tr>
    <nested:iterate property="listOfFields">
    <td>
       <nested:text property="myField">
    </td>
    </nested:iterate>
 <tr/>
 </nested:iterate>
</table>
</nested:form>

Hi,
i have been trying to create a table on my form from a single property in 
my actionForm. the property is a List (actually an ArrayList) containg 
the rows of the table, each element (i.e row on the table) is represented 
by a List of Strings representing the fields of the list. i can code my 
JSP page to display the contents of the proprety in a table but i cant 
get it to set the values of the property from the page on submit. all the 
efforts has failed, i my latest effort, i coded the property as 
property[row][col] but i get an error that dia is no getter method for 
property[0][0]. i wrote the access methods like
String getProperty(int row, int col){
return  (String)((List)property.get(row)).get(col);
}

it did not work, any ideas will be apreciated.
