cannot display by cck date

i tried installing the newest dev versions of both cal and date and then the following error occurs on every page:
Fatal error: Call to a member function on a non-object in /htdocs/sites/all/modules/views/includes/view.inc on line 378
so i went to back to the beta version

i noticed that even tho the javascript popup 'an error has occured' displays, the argument/filter gets inserted anyways, so i added the cck date field as a filter to my calendar view, but then i had an error of:
call to undefined function granularity_keys() in date/date/date.views.inc on line 1212

i commented out that line, and that got rid of the error, but now nothing shows up in my calendar.
i removed that filter and it went back to displaying the node on the day it was created (not on the cck date)

i tried the same method with the argument. added it, ignoring the popup error, and now the argument is there, but it is set to Argument format: YYYY-MM-DD and i think i need it to Argument format: now-now-now (?) but i can't edit it because of the javascript ajax error when i click on it.
it says "an error has occured in the popup, but this is the console message from FF web dev plugin, if it helps:

Fatal error: Cannot unset string offsets in /htdocs/sites/all/modules/date/date/date.views.inc on line 1237


tried finding where the views argument is stored in the database but no luck (with drupal 5 it was in views_arguments table, but that seems to be gone now with d6).

any help on any of this?

ok, i think i got this working.
it took quite a bit of monkeying around, but i'll try to explain it all here, and i hope i don't miss a step.

the javascript 'an error has occured' errors seemed to be coming from timezone problems, so i commented out lines 918. 919, and 920 in date/date/date.views.inc

in date/date_api_sql.inc i did the following:
- comment out lines 184-192, and line 153. 154, 155
- remove the extra T in line 157 so the time format looks like: '%Y-%m-%%d %T'

i saw there was a similar sql error in this bug: http://drupal.org/node/262556
so i followed his 'fix' and in views/includes/query.inc i found the add_field function on line 576 and added this to the first line of the function:

  // make sure field isn't empty
  if (empty($field)) return;
  

finally, in your view UI in the admin, change the Calendar: Date argument to use your node's CCK date field, whatever you happened to name that, instead of the node changed date.

after all that, it seems to be displaying correctly with the node displaying in the calendar on the date in the cck date field, instead of the date it was created/updated.

i hope i remembered all the changes i made, and i have no idea if these changes will break other things, so the normal disclaimers apply (make sure to backup your db and files before trying this stuff) but they got my site working how i needed it.

hope this helps someone...
