Help testing the CCK Multigroup module

New version of the multigroup module in comment #245 of this issue: #119102: Combo field - group different fields into one (multi value fieldgroup?).

Changes since latest update:

• The required attribute of fields is applied to the scope of a single sugroup of fields. If a subgroup is used, it contains any non-empty field, then required fields are required, heh. If a subgroup is not used, all fields are empty, then required fields are not required, and FormAPI will not complain about that. The required star is displayed for required fields, but the validation is skipped when the whole subgroup is empty. It was tricky, but I believe I got it.
• There is a new option for multigroups: required. It's available from the multigroup settings form. When enabled, a minimum of one collection of fields in that Multigroup is required.
• There is another new option for multigroups: Multiple columns. Also available from the multigroup settings form. When enabled, each field is rendered on a separate column on the node edit form.
• There is a new display option for multigroup subgroups: Table. There was a TODO note on the multigroup module to implement this feature. Now, it's done.

I hope you find it as useful as we do! :-D

Please, test and report back any issues that you may find. This will help the CCK maintainers evaluate it all, and maybe we can count on it for a future CCK release.

Thank you

Here's an updated version of the multigroup module. :-D

Combo field - group different fields into one (multi value fieldgroup?) - #286

Changes since latest version:

• Bugfix: red asterisk bug when pressing "Add more values" button (see comment #280)
• Bugfix: required attribute for field set to FALSE always, not just when delta > 0 (see comment #282).
• Bugfix: error messages related to required attributes consistent with FAPI (see comment #282).
• New feature: Table display mode for subgroups has been splitted into a couple of variants. 'Table - Single column' renders all fields on a single cell. 'Table - Multiple columns' renders each field on a separate column (equivalent to previous table display mode).

Required and/or recommended patches:

• Don't forget that this module requires the latest patch to CCK2 in #196421: Deleting unwanted multiple values / multiple values delta issues
• For those using Date fields: #324290: warning: array_key_exists() [function.array-key-exists]
• For those using Computed fields: #349548: Conditional result for hook_content_is_empty()
• For those using Content Taxonomy: #350669: Add support for the content multigroup module?

Please, don't try on production sites! ;-)

Again, I'm attaching the content multigroup module in patch form, but also all the module files tar'd for easy the task of testing it.

Thank you very much to all those that have tried. Your feedback has been great! :)
