In case someone else is trying to do the same thing, here is the
solution I came up with. Using a multiple s:checkbox instances with a
name that points to a String[] did not give the results I wanted so I
had to bag that idea. Instead I did this ...
Action:
private String[] deleteIds = new String[0];
public String[] getDeleteIds();
public void setDeleteIds(String[] ids);
Jsp:
<s:iterator id="entry" value="someCollectionOfObjects">
<s:checkboxlist name="deleteIds" list="{#entry}" listKey="id" />
// do any other work using #entry
</s:iterator>
with this I can call getDeleteIds() in my action after a submit and it
will return a String[] of all ids that were checked for deletion. also,
when the form is being populated in the jsp it will automatically check
the box for each entry that had its id in the deleteIds array, so if
there is a submission error then the checkboxes are properly repopulated.
the only downside so far is that s:checkboxlist automatically creates a
label for each checkbox, which may not be desired. i am just using css
to "display:none" those labels as a work around, which isn't the best
case scenario, but it works.

Okay, I guess that s:checkbox can do what I want but I am having trouble
getting the multiple values from the results of my checkboxes. So if I
have this ...
<s:iterator id="entry" value="myCollection">
<s:checkbox name="deleteIds" fieldValue="%{entry.id}" />
<s:checkbox name="disableIds" fieldValue="%{entry.id}" />
</s:iterator>
and in my action ...
private String[] deleteIds = new String[0];
public String[] getDeleteIds();
public void setDeleteIds(String[] deleteIds);
// same thing for disableIds
I think that should work but I'm not getting the values that I expect.
When I check only a single box it seems to submit values for both the
delete and disabled boxes, and if I check multiple boxes I only get a
single value.
I am also curious why there are 2 inputs for my checkboxes ...
<input type="checkbox" name="deleteIds"
value="0112f2dd1248f33f011248f6bcb40004"
id="globalCommentManagement_deleteIs"/>
<input type="hidden" name="__checkbox_deleteIds"
value="0112f2dd1248f33f011248f6bcb40004"/>
is String[] the right type to use for collecting the values of the
checkboxes? why am i not getting the multiple values and why are the 2
checkboxes affecting each other?

actually, I did have trouble getting it to work but it doesn't really
matter because that's not really what I am looking for. That tag will
create a whole list of checkboxes, but what I really need is to create
a single checkbox which is part of a list. It's a weird situation so
it wouldn't really surprise me if s2 didn't have support for it, but I
wanted to ask.
in any case, the situation is that i am iterating over a collection
and displaying each entry in a list on the page. in that list i am
providing a couple of checkboxes which affect the status of that
entry, 1 which would delete the entry, the other which would set a
different status. so my basic code is ...
<s:iterator list="myCollection">
<tr class="entry">
<td> // delete checkbox </td>
<td> // status checkbox </td>
<td> // print entry details </td>
</tr>
</s:iterator>
so i'm not really trying to print a whole list of checkboxes, i'm
trying to print a single checkbox which is based on a list. it looks
like that's what the old html:multibox tag was for, but i dunno, i
didn't write the original code that i am updating :/

Is there a direct equivalent struts2 tag to the

code being migrated and i'm not sure how best to accomplish the same
thing in struts2 ...
Does <s:checkboxlist.../> not work for you?
