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

[Olasoji Ajayi]

if this works, it will take care of writing the table to the jsp but i need 
an html input type of field so i can also set the properties of the 
ActionForm by editing the fields and submiting the form.

Hi,
There is a way :
<table>
<logic:iterate id="row" name="myForm" proprties="listOfRows">
   <tr>
   <logic:iterate id="myField" name="row" proprties="listOfFields">
       <td>
           <bean:write name="myField"/>
       </td>
   </logic:iterate>
   </tr>
</logic:iterate>
</table>
Regards,
Cedric

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


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
