RE: Struts Bug? My Bug? Help!! Please!
Thank you!
I forgot about that. Thanks for jogging my memory. I know I've read about
that in the mailing list somewhere before, but I couldn't find it. I
appreciate your quick response.

Hi Becky,
Did you override the reset () method of ActionForm? If you didn't you
need to set the Attribute of your ActionForm object that represents the
multibox to null.
Like:
public void reset(ActionMapping mapping, HttpServletRequest request) {
this.action = "Create";
this.autoConnect = false;
this.yourMultiboxNames = null;
}

RE: Struts Bug? My Bug? Help!! Please!
Here is a simplified overview of what you need to do. If you still would
like code, I can still supply you with it, but I think this will be easier
to understand.
ActionForm:
2 fields with associated getter and setters:
String[] CheckboxNames
String[] CheckboxValues
You must populate this form before you hit the JSP to display it (if you
want to preset the values). So, figure out all the possible values, and
then figure out what you want checked. So, for example...
checkboxNames[0] = "String1";
checkboxNames[1] = "String2";
checkboxNames[2] = "String3";
checkboxNames[3] = "String4";
and
checkboxValues[0] = "String2";
checkboxValues[1] = "String4";
Then say
MyForm form = new MyForm();
form.setCheckboxNames(checkboxNames);
form.setCheckboxValues(checkboxValues);
And put the form in the session.
When you get to your jsp, retreive the form from the session, and place it
into the page context:
pageContext.setAttribute("MyForm", myform , PageContext.PAGE_SCOPE);
Then, where you want the multiple checkboxes on your jsp, do the following:
THen when you press submit and go to your actionClass, you can compare
CheckboxNames to CHeckboxValues to see what was checked.
Did that explain it enough?
Hope it helps,
Becky
