EhibitView: add numeric valueType for fields which have a numeric handler

Issue Summary

i have a view for my custom module, where i have a numeric field. In order to use the Slider facet, the valueType for this field must be set to "number". For CCK fields the value type is set, as far as i can see, but non-cck fields not.

For me this hack works for now:

in file: views_plugin_style_exhibit_json.inc - add this lines at line 80

if ($field instanceof views_handler_field_numeric)
$props[$id]['valueType'] = 'number';

would be great if someone with more clue about this module could, enhance this solution (if needed) and provide a patch!

thank you very much!

have a nice day!
