Re: Can a collection property have its changes saved back to the ActionForm?
Thanks Adam. I ended up using your solution. I'm not thrilled about the user
seeing the listbox items get auto selected after they submit the form, but the
code is certainly cleaner than adding and removing hidden controls. For the
archives, here's what I went with:
JSP
function setStatus() {
var emailSelect = document.getElementById(emailSelect);
emailSelect.multiple = true;
emailSelect.focus(); // This is needed to force IE to execute the line
above.
for (var i = 0; i emailSelect.length; i++) {
emailSelect.options[i].selected = true;
}
}
html:select name=formName property=addresses
onchange=setEmailButtonStatus(); size=4
html:options name=preferencesForm property=oldAddresses/
/html:select
ACTIONFORM
private String[] addresses;
public String[] getAddresses() {
return addresses;
}
public void setAddresses(String[] value) {
addresses = value;
}
private final ListString oldAddresses = new ArrayListString();
public ListString getOldAddresses() {
return oldAddresses;
}
Thanks again,
Andrew

you want to save the options in the select not a selected option...
if you make the select a multiple select and in javascript you select all
options are all the option values sent to the server against the same
parameter name (turn on parameter interceptor logging to check)...
if so, add a set method in your action with the same name as the select element
that accepts a string array, like
setNewRole(String[] newRoles)
inside this method you can initialise your proper ArrayList and add the
elements from the string array into it.
you still need the javascript to select options but at least you're not
creating new elements.
i haven't checked if multiple selects sends its parameters in this way but it
works when multiple checkbox elements all have the same name and are sent as
name/values pair.
ps. if i've misunderstood and you just want to save multiple selected options,
then you can omit the javascript part which would be better.

elements to the document corresponding to the new values in the select. The
names of the hidden elements will be indexed. Something like this:
Action Form:
public List getOldList()
public String getSelectedValue()
public void setNewList(int index, String value)
JSP:
Then the setNewList method gets called on the form with the new values from
the select box.
If anyone has any better ideas I'm open to hearing them, but this seems to do
the trick.

Subject: Can a collection property have its changes saved back to the

Hello all,
I have a List collection that I am displaying in an
and it is working great. The problem is that my
jsp page makes changes to that control via
javascript (adds new options, removes, etc). I would like these
changes to be saved back to the ActionForm, preferrably to the same
collection where it got its data from.
Struts does not seem to do it by default, that is, the
tag seems to make use of the ActionForm's get
property, but not its set. If it is supposed to behave this way please
let me know and I will reexamine my syntax. Otherwise can someone tell
me the easiest way to do this? I am using Struts 1.3.8 and
unfortunately cannot upgrade to Struts 2.
Many thanks in advance,
Andrew

Re: Cannot find bean: sendJsp in any scope
Along with the change I suggested, you also need to add a public getName()
method to your Book object. Try that, and also make sure you can get a simple
String property to display to ensure you have Struts configured properly.
If you still have trouble let me know and I ll come up with a working example
for you tonight.

Re: Cannot find bean: sendJsp in any scope
I found a full example for you here:
http://www.java2s.com/Code/Java/J2EE/StrutsFrameworkASampleStrutsApplication.htm
You'll notice that the name property of the logic:iterate tag is set to the
form name as used in struts-config (in your case, BookForm).
Assuming data.jsp forwards to BookAction, you should not need to put the book
list on the request as you are doing in the execute method of the BookAction.
Again I suggest you try to get a simple String property on the action form to
display in your browser and then work your way up to the collection.
Good luck!
Andrew

Re: Can a collection property have its changes saved back to the ActionForm?
For the archives, the solution I'm going with is to have the javascript add
html:hidden elements to the document corresponding to the new values in the
select. The names of the hidden elements will be indexed. Something like this:
Action Form:
public ListString getOldList()
public String getSelectedValue()
public void setNewList(int index, String value)
JSP:
html:select name=formName property=selectedValue styleId=myId
html:options name=formName property=oldList/
/html:select
html:submit onclick=saveSelect()/
script type=text/javascript
function saveSelect() {
var selectControl = document.getElementById('myId);
for (var i = 0; i select.length; i++) {
var hid = document.createElement(input);
hid.type = hidden;
hid.name = newList[ + i + ];
hid.value = selectControl.options[i].value;
document.forms[0].appendChild(hid);
}
}
/script
Then the setNewList method gets called on the form with the new values from the
select box.
If anyone has any better ideas I'm open to hearing them, but this seems to do
the trick.
