Hi,
I found that the easiest way to do this is to use LazyLists. (cf.
http://wiki.apache.org/struts/StrutsCatalogLazyList). You can then work just
as you
with fixed lists. An example:
in my jsp I have something like ...
<logic:iterate name="FgZuordnungForm" property="zuordAll" id="zuordAll">
<tr>
<td><html:text name="zuordAll" indexed="true" property="from" /></td>
<td><html:text name="zuordAll" indexed="true" property="to" "/></td>
</tr>
</logic:iterate>
<span Id="fgzList"></span>
(Note the indexed="true"). I have a javascript function that creates more
table rows
where the <span...> stands. These rows look just like the ones created by
the
html:text tag, except that the array-index is increased, i.e.
... myInput.setAttribute('name','zuordAll['+row_cnt+'].'+ 'from');
In the corresponding form, the List is simply declared as
private List zuordAll=ListUtils.lazyList(new ArrayList(),
new Factory() {
public Object create() { return new ZuordData();
}
});
plus the normal setter and getter. (ZuordData is just a bean with properties
from and to).
Thats all. You can pass in a List of size n, add a few rows using Javascript
and,
after submitting the form get out a List of size n+k.
Rather simple once one has figured it out.
Hope that helps,
Ulrich
