Thanks for that - but I think I've not explained my problem properly.
The problem is that the bean containing the data is NOT the one in the
inner loop but the bean iterated through in the outer loop:
<logic:iterate name="applicationForm" property="familymembers"
id="familymmber" type="application.FamilyMember">
I want to be able to access as from within the inner loop.
familymembers[0].surname, familymembers[0].forename,
familymembers[1].surname, etc.
The reason for this is that the form needs to show and allow editing of
different data depending on who is accessing it. Yeah, I know it makes
things complicated but it's what THEY want. The inner iterate is around
a form configuration bean which describes the data which should be
displayed:
<logic:iterate name="applicationForm" property="familyItems"
id="formItem" type="utils.InputItem">
InputItem has fields which describe the type of input field to be used
and whether it is displayed, readonly, mandatory, etc.
i.e. inputitem is an array with entries something like - there are other
fields to hold any option lists for select items, etc. but those aren't
really relevant to this problem.
inputitem[0]
property=surname
readonly=false
size=30
type=text
mandatory=true
inputitem[1]
property=forename
readonly=false
size=30
type=text
mandatory=true
and I want to end up with html like this.
<!-- First Row -->
<input type="text" name="familymembers[0].forename" value="">
<input type="text" name="familymembers[0].surname" value="">
<!-- 2nd row -->
<input type="text" name="familymembers[1].forename" value="">
<input type="text" name="familymembers[1].surname" value="">
but because the iterator count is picked up from the inner loop - I end
up with
<!-- First Row -->
<input type="text" name="familymembers[0].forename" value="">
<input type="text" name="familymembers[1].surname" value="">
<!-- 2nd row -->
<input type="text" name="familymembers[0].forename" value="">
<input type="text" name="familymembers[1].surname" value="">
<!-- 3rd row -->
<input type="text" name="familymembers[0].forename" value="">
<input type="text" name="familymembers[1].surname" value="">
I've done this successfully using a similar technique when there is a
single data item to be edited but this form needs to be able to edit
multiple rows at once and I'm hitting a problem with the iterator.
I guess what I really need is a way to iterate round the inner loop
without the counter used for indexing being increased.
Again, thanks for any help anyone can give.

Hi Mike
Maybe I'm simplifying it somewhat and I'm not sure of your form-bean structure,
however the outer loop should loop through 'familymembers' as it is looping it should
set a form-bean for the inner loop identifying a 'familymember'. I also like to add the
type here - helps my inline documentation. So, outer loop should be:
<logic:iterate name="applicationForm" property="familymembers" id="familymember"
type="controller.form.FamilyMemberForm">
Then we can add the inner loop in a similar manner, referencing the 'familymember'
defined in the outerloop:
<logic:iterate name="familymember" id="familyitem"
type="controller.form.FamilyItemForm">
Finally we can then display the input box for these items:
<html:text name="familyItem" property="dataProperty" size="${familyItem.size}"
readonly="${familyItem.readonly}">
Maybe this is too simplistic, sorry if I've missed the point somewhere.
Kind regards

Hi,
I have a problem trying to create a multi row edit form which has to be
able to dynamically decide which columns should be displayed for edit.
My jsp uses the code below.
<logic:iterate name="applicationForm" property="familymembers"
id="familymembers">
<tr>
<logic:iterate name="applicationForm" property="familyItems"
id="formItem">
<td>
<logic:notEmpty name="formItem">
<% InputItem inputItem = (InputItem)formItem; %>
<logic:equal name="formItem" property="type"
value="text">
<html:text size="<%= inputItem.getSize() %>"
readonly="<%= inputItem.isReadonly()%>" name="familymembers"
property="<%= inputItem.getDataProperty() %>" indexed="true"/>
</logic:equal>
</td>
</logic:iterate>
</td>
</logic:iterate>
The outer iterate is the bean holding the data - in this case a list of
family members - name, gender, date of birth. The inner iterate is the
list of fields to be displayed for each, My problems is that when this
is rendered as html - the index values generated use the index of the
inner iterate not the outer one - so I get
<tr>
<td>
<input type="text" name="familymembers[0].forename" value="">
</td>
<td>
<input type="text" name="familymembers[1].surname" value="">
</td>
</tr>
<tr>
<td>
<input type="text" name="familymembers[0].forename" value="">
</td>
<td>
<input type="text" name="familymembers[1].surname" value="">
</td>
</tr>
whereas what I want is
<tr>
<td>
<input type="text" name="familymembers[0].forename" value="">
</td>
<td>
<input type="text" name="familymembers[0].surname" value="">
</td>
</tr>
<tr>
<td>
<input type="text" name="familymembers[0].forename" value="">
</td>
<td>
<input type="text" name="familymembers[1].surname" value="">
</td>
</tr>
I have also tried using nested:iterate as well - in which case I get
<tr>
<td>
<input type="text" name="applicationForm[0].familymembers[0].forename"
value="">
</td>
<td>
<input type="text" name="applicationForm[1].familymembers[0].surname"
value="">
</td>
</tr>
<tr>
<td>
<input type="text" name="applicationForm[0].familymembers[1].forename"
value="">
</td>
<td>
<input type="text" name="applicationForm[1].familymembers[1].surname"
value="">
</td>
</tr>
so the familymembers index is now correct but I have an additionally
applicationForm[0] that I don't need.
Basically what I want to achieve is that the inner loop is ignored for the purposes of
generating the indexing for the html output - but can't figure out to achieve that without
writing my own tag.
Can anyone help?
Thanks
Mike Manley
