Ordering by 'date' field: how to? [Fixed]

I'm developing a website containing many Flexicontent items (grouped under subdirectories) to be ordered by a custom "date type" field.
The website contains several press review subdirectories, where each item represents a press review issued in a certain date. When opening a directory, the item list must be ordered by the press review printing date (that is a date type field), in descending mode (the first visible review must be the more recent one).
I can't find a direct way to order the directory content by a 'date type' field, it seems that only text fields are allowed to be used as custom ordering field.
Is there a way to get it working?
I have also tried to use the default ordering, but I can't find an easy way to order items assigned to a subdirectory (ordering item in subdirectories doesn't work, I have read that this behaviour depends on the multiple assignment that a item can have, but I think that it should be found a way to get ordering working anyway...).
I'm using the latest RC4 release, on Joomla 1.5.25
Any help is appreciated
Thank you in advance

mmm, there is no reason not to allow ordering by date,

I have incorrectly excluded date and other fields from having ability to be used for ordering, will commit a small fix for this, excluding only certain fields, e.g. toolbar field,

To have a quick fix now, please edit :
administrator/components/com_flexicontent/models/category.xml

change line:
<param name="orderbycustomfieldid" type="fields" field_type="text" ....

to
<param name="orderbycustomfieldid" type="fields" field_type="" ....

Thanks for bringing this up

Regards

Great! Thank you so much for the hint.

A further suggestion: could it be usefull to add another cascading ordering selectable field (or a couple of fields)? i.e, in my case, I should sort events at first by the "from date" field, than by location (alphabetically).
Yes, it's not an essential feature, but it could help to refine the "first shot" ordering.

Thank you again for this great component

p.s.: it seems that ordering works only for categories having subdirectories: is that my fault?

Subcategories must not be related,

what you mean it is not working, you mean the frontend is showing no items or the ordering is not working?

Do the items of this category have multiple values for the date field?

I try to better explain what I have.

The Category structure is like this:
main-level ___ first-sublevel--first-dir ___ second-sublevel--first-dir-a
....................|..............................................|__ second-sublevel--second-dir-a
....................|
....................|___ first-sublevel--second-dir ___ second-sublevel--first-dir-b
..........................................................................|__ second-sublevel--second-dir-b

main-level and first-sublevels have no items assigned
seconds-sublevels have various item assigned

I order all levels by a "date" field

main_level is correctly ordered by that date field, and also all the first_sublevels

second_sublevels (the ones having items assigned, with no subcategories assigned) are not ordered by date, but by default ordering

obviously all cat have the same setting (cloned from the first one):
- Display subcategories' items: all sublevels
- ordering by "date" custom field
