Problem with html:multibox not clearing
I am using an html:multibox that is pretty much working fine except when I
uncheck all choices. I am also using the logic:iterate tag to generate many
checkboxes. If I have a single box checked I can't seem to uncheck it if
it's the last one. If I have several checked, I can uncheck them one at a
time and that works. At least until I get down to just one checked. Very
odd. The problem seems to be that I can't get Struts to realize that there
are no checkboxes checked after I submit the form.
I am using struts 1.1, with DynaValidatorForm's. Here's some of my code:
...
<form-property name="amenity" type="java.lang.String[]" />
...
<td colspan="4">
<logic-el:iterate id="item" name="amenities" indexId="i">
<html-el:multibox property="amenity">
<bean:write name="item" property="code"/>
</html-el:multibox>
<bean:write name="item"
property="description"/>
</logic-el:iterate>
</td>
Don't think the above is the issue. It's something deeper I think.
Any help is appreciated.

Sorry, I missed the part that said your form was in the
session.
And I also forgot that I do subclass my DynaValidatorActionForm and
add the following code to the reset().
public void reset(ActionMapping mapping, HttpServletRequest request) {
this.initialize(mapping);
}
It works for me. Good luck with your solution.

RE: Problem with html:multibox not clearing
Posted by Jim Kennedy <jk...@davincitechnology.com>.
Just an FYI, this did not work. I don't believe it's a reset() issue. From
other threads, it's the way an http request is sent when no checkboxes are
selected. Since nothing gets sent, nothing gets changed. I will write some
JavaScript to manually check to see if anything has been checked. If no
boxes are checked, I will artificially create a form element that has the
same name as the checkboxes.
That's my solution.
L8r and thanks

Jim, you can try this in your dynavalidatorform declaration:
<form-property name="amenity"
type="java.lang.String[]"
initial="{}"/>
When you invoke an action, Struts will automatically reset your form.
So when you hit submit, Struts will invoke form.reset() which will reset all
your form properties to their initial values.
If you declare your initial value as an empty array (as above), then if
nothing is checked, the array will be empty. If something is checked, it
will be populated by the values in the request.
Give it a try.

RE: Problem with html:multibox not clearing
Posted by Jim Kennedy <jk...@davincitechnology.com>.
That's not what I had in mind. Thanks for the suggestion though. I found a
thread that suggests that you must subclass dynavalidatorform and override
the reset() method. Not really sure how that will help.
My form is a multipage form and the dynavalidatorform is in the session.
I now know why it happens, but are there any other suggestions?

This is an HTTP problem. If the user clears all the checkboxes, the browser
doesn't send anything back to the server. In this case, it seems that all
the checkboxes still have their default value.
To fix this, I included a hidden checkbox on the form that is always
checked. The user can't see or modify it, so it will always remain checked.
This ensures that the browser will always send back the checkbox list, even
if all the checkboxes that the user can see are cleared.
