Thanks, that was definitely it; I checked by using a value I know is in
the "items" list instead of -1, and it ended up as the default.
I appreciate the help!

My guess is that the headerKey attribute is always evaluated as a string.
Since you're using a List<Integer>, even if the string representations are the
same, it won't match (see [1]).
That's probably worth an "improvement" JIRA if there isn't one in there
already, although I haven't looked at it to see how easy/hard the change would be.

Subject: Problem with creating default selection values in multiple select

Hi,
I'm relatively new with Struts2, but I'm starting
to get a handle on how
things work. However, I'm having a problem with
creating a "default"
list of pre-selected values for an <s:select> tag
when using the
"multiple=true" option. It works fine when I use
single selection, and
when the "pre-selected" values are loading by the
framework
automatically, but I can't seem to get a
manually-created list to select
anything.
Here is the struts tag I'm using (altered slightly to
remove
project-specific details):
<s:select headerKey="-1"
headerValue="Any Item"
id="pickedItem"
label="Item"
list="items"
listKey="itemId"
listValue="itemVal"
multiple="true"
name="pickedItems"
size="8"
value="selectedItems"
/>
the list/listKey/listValue all seem to work fine, as far as
I can see.
itemId is an integer.
the value of "selectedItems" calls the
"getSelectedItems" from an Action
class I'm using. The code for that is as follows:
public List<Integer> getSelectedItems() {
if (pickedItems == null || pickedItems.size() == 0)
{
List<Integer> defaultList = new
ArrayList<Integer>();
defaultList.add(-1);
return defaultList;
} else {
return pickedItems;
}
}
pickedItems is sometimes populated automatically by an
AJAX-based action
call, and the list on the screen is refreshed; the
previously selected
items remain selected. However, when the page first loads,
I want it to
automatically select the "Any Item" option.
I'm using Struts 2.0.11.1
Thanks!
Scott
