--------------------------
> Unable to clear fields once they're set
> ---------------------------------------
>
> Key: STS-100
> URL: http://www.stripesframework.org/jira/browse/STS-100
> Project: Stripes
> Issue Type: Bug
> Components: ActionBean Dispatching
> Affects Versions: Release 1.1
> Reporter: James Stangler
> Assignee: Tim Fennell
> Fix For: Release 1.1.1
>
>
> Once a field is set, there's no way to remove its value. The method that
> converts the values from Strings to their real property types,
> OgnlActionBeanPropertyBinder.convert(), discards empty strings. When this
> method is called from the bind() method, the List of converted objects is
> empty and the setter is never called.
> Checkboxes also have this problem but have an additional issue in that
> browsers don't send the parameter at all if it isn't checked so there's no
> way to detect that a checkbox has been cleared from the parameters. A
> possible solution might be to generate a hidden field in the html for every
> checkbox group name. The submission of this hidden field could check to see
> if the real checkbox field had any values submitted and if not clear the
> value in the data object (either boolean or a list/array structure).
