Hi,
 
i don´t think so, because i do not have a "department -> customer" structure
(1 to many structure). i only have a list of objects, each object has 3
properties (a, b, c) of type integer (a,b,c can have a value from 0 to 2).
 
I want to display a list of these ojects and 3 groups of either 3
radio-buttons. if the value of a is 2, the last radio-button of the first
group is selected, if the value of c is 0, the first radio-button of the 3rd
group is selected ...
 
OBJECT1  0  1  2   0  1  2   0  1  2    (0,1 and 2 is always a group, i can
select one of the entry, 0 or 1 or 2 in each group -> so i will get for a,
b, and c a value of 0, 1, or 2)
OBJECT2  ...
...
 
To display this is not the problem, this is alread working, my ActionForm
has a property of "rights" which in an Array of my objects.
private Right[] rights;
 
The problem is, when i´m submitting the form, i do not get the valus, the
array is either null, or, if i use the modified version (see below) i get a
[BeanUtils.populate]: java.lang.NullPointerException :-((
 
Can anyone help me in this case? Or does the nested-tag really is required
for that - but i dont think so ... it has to work with iterate too, doesn´t
it?
 
thanks in advance
Hans

Hey Hans,
    I think you might want to use the nested tags for what you are trying to
do.  Depending on the version of struts you are using, the nested taglib
could be included with the Struts distribution.  Here is a link to some
tutorials etc. on the nested tags

Hi,

does anyone knows a really good docu (with examples) how to use the
iteration (with indexed tags)?

Because my indexed iteration is not working, the first time the values are
fine (loading), but after submitting the data, the changes are not mapped to
the array (or arraylist).

Here is the problem again, maybe someone knows a good doc or has an idea
...?

I have modified the iteration from <logic:iterate id="right" ... to
<logic:iterate id="rightlist_ary" ... because that's my array I want to have
filled, but after submitting the form I get ... 
[BeanUtils.populate]: java.lang.NullPointerException

any ideas? help would be great, thanks.


*** *** ***

i have a problem with the logic:iterate tag ... i want to show a list of
objects (which habe attributes with values of 0 or 1 or 2)

I want to show them in a list of radio-elements

OBJECT 1 0 1 2 0 1 2 0 1 2
OBJECT 20 1 2 0 1 2 0 1 2
...

where 0,1,2 is a radio-element (one of 0 or 1 or 2 can be choosen).



public class AuthRightForm extends ActionForm {

private Right[] rightlist_ary;

get / set ...

// after loading
rightlist_ary = new Right[10];
// filling rightlist_ary from DB ...
...


<logic:iterate id="right" name="authRightForm" indexId="idx"
property="rightlist_ary">
<tr>
<logic:present name="right">
<logic:notEmpty name="right">
<td><bean:write name="right"/>, Index = <bean:write name="idx"/>

<td><html:radio name="right" property="val_owner" value="0"
indexed="true"/></td>
<td><html:radio name="right" property="val_owner" value="1"
indexed="true"/></td>
<td><html:radio name="right" property="val_owner" value="2"
indexed="true"/></td>

</td>
</logic:notEmpty>
</logic:present>
</tr>
</logic:iterate>


The displaying of the values is working, so if Object 1, property 1 has a
value of 2, the 3rd radio-element is selected - this works fine. But, after
submitting the form, I do not see the changed values (if I change the
radio-buttons). The value of rightlist_ary is always null - so I do not see
any objects in the list any more.

The request-object has values like that:
right[3].val_owner -> 1
right[2].val_owner -> 2
right[1].val_owner -> 1
...

Does anyone has a solution for that?

Thanks a lot
HP
