Subject Re: Can't uncheck multibox
Date Tue, 23 Sep 2003 06:58:42 GMT
Hi,

I had this problem when I placed my ActionForm in the Session. I noticed that when I uncheck
all the checkboxes, the browser would transmit no value for the checkbox property and so the
ActionForm property would not be updated to an empty String[] as I had expected. 

<html:multibox property="actionItemIndicator">
   <bean:write name="defectsList" property="defectId"/>
</html:multibox>

If you uncheck all the checkboxes in your example, the request query string parameter "actionItemIndicator"
would not be transmitted. i.e. there would be no "&actionItemIndicator=" in the query
string. Most browsers dont transmit parameters when they have no values.

I worked around this problem by checking if this parameter was null, and then implicitly set
the property to an empty String[];

eg. In the Validate Method()
...
if (httpServletRequest.getParameter("actionItemIndicator") == null) {
  actionItemIndicator = new String[] {};
}

HTH.

Can anyone help???  I have the following multibox in a
dyanValidatorForm:

<logic:iterate id="defectsList" name="reviewRecordForm"
property="defectsList" indexId="i">
       <html:multibox property="actionItemIndicator">
               <bean:write name="defectsList" property="defectId"/>
       </html:multibox>
</logic:iterate>

I am having trouble unchecking the checkboxes.  Everytime I uncheck a
checkbox, hit submit, when the screen comes back the checkbox is still
checked.  When I extract, the form data from this property, the form
still indicates that the checkbox is checked even though I unchecked it
in the form....

How do I uncheck a box once it has been unchecked by the user???

Thanks in advance,

Natalie
