wizard form and checkboxes that won't turn off
Could somebody please refer me to a solution to this?
I have a form bean (session-scoped) that is displayed over 3 pages. There
are "back" and "next" buttons. Once a checkbox is selected and the user has
moved to another page, it can't be cleared again. I have read that this is
because the checkbox item is now in the session and simply unchecking it
does not remove it from the session. What I haven't found is a solution or
workaround.
I am using struts 1.1.
Thanks very much in advance,
J

Thanks James, now all the other stuff that I read about reset makes
sense. I had been assuming that since I don't have a reset function
for my form that I didn't need it.
Now I'm having issues with my nested forms. Does anyone have a
recommendation on how to deal with them?
This is what I've done:
<... snip from reset method ...>
if (thePage == 2) {
if (map.containsKey("dfcAPInd")) map.put("dfcAPInd", Boolean.FALSE);
subformReset("projectTypes", map, actionMapping,
httpServletRequest);
<... end snip from reset method ...>
<... snip subformReset method ...>
private void subformReset(String key, Map map,
ActionMapping actionMapping, javax.servlet.http.HttpServletRequest
httpServletRequest) {
if (map.containsKey(key)) {
ArrayList list = (ArrayList)map.get(key);
Iterator it = list.iterator();
DynaValidatorSimpleXrefForm widgetFormBean;
while (it.hasNext()) {
widgetFormBean = (DynaValidatorSimpleXrefForm)it.next();
widgetFormBean.reset(actionMapping, httpServletRequest);
}
}
}
<... end snip subformReset method ...>
The reset method in the nested form only resets a couple of
checkboxes. But now I get validation errors. The validation on the
nested forms is as follows:
<... snip validation ...>
<form name="SimpleXrefForm">
<field property="isSelected" depends="requiredif">
<arg0 key="xref.isSelected"/>
<var>
<var-name>field[0]</var-name>
<var-value>comments</var-value>
</var>
<var>
<var-name>fieldTest[0]</var-name>
<var-value>NOTNULL</var-value>
</var>
<var>
<var-name>field[1]</var-name>
<var-value>BMGS</var-value>
</var>
<var>
<var-name>fieldTest[1]</var-name>
<var-value>NOTNULL</var-value>
</var>
<var>
<var-name>field[2]</var-name>
<var-value>ADDL</var-value>
</var>
<var>
<var-name>fieldTest[2]</var-name>
<var-value>NOTNULL</var-value>
</var>
<var>
<var-name>fieldJoin</var-name>
<var-value>OR</var-value>
</var>
</field>
</form>
<... end snip validation ...>
It is like all the nested forms throw an error if they haven't been
filled out at all. So if I have 10 projectTypes and I check off 3 of
them, I get 7 errors.
Any ideas? Thanks in advance, J

Re: wizard form and checkboxes that won't turn off

The problem is that the browser submits a value of "on", when you check a
checkbox and submit the form. However, if you uncheck the checkbox and
submit the form, the browser does _not_ submit "off" or "false" or anything.
So, with your form sitting in session, how will it know that you want it
"off"?
Here's how: you need to implement reset() method on your form. In that
method you need to set the field that is backing the checkbox to "false" or
"off". When Struts processes the request, it will call reset, then
repopulate based on request....effectively giving the _appearance_ that the
browser sent "off".
