Can never format a Collection/Array using custom formatters with certain
Stripes Tags
-------------------------------------------------------------------------------------
Key: STS-878
URL: http://www.stripesframework.org/jira/browse/STS-878
Project: Stripes
Issue Type: Bug
Components: Formatting, Tag Library
Affects Versions: Release 1.5.6
Reporter: Martin Walsh
Certain tags within the Stripes Taglib do not allow you to work with
Collections or Arrays. All tags that use
InputTagSupport.getSingleOverrideValue() to obtain the override value for the
field get returned the first value in the Collection/Array which is then passed
to the Formatting framework to format. This prevents users from displaying a
formatted list of the values, instead always displaying the first value in the
collection, even when a CollectionFormatter is present.
What I think should happen is that the tags should use
InputTagSupport.getOverrideValueOrValues() and pass the resulting Object off to
the formatters. That way a CollectionFormatter could then be used to format
the values accordingly, whether that be to return the first value in the
Collection to maintain current behavior, or return a comma separated list of
values so that data values are not lost. This also allows overriding to
customise the output, which is currently not possible for Collections/Arrays.
