Errors if Node Settings are not saved

Hi,

I get the same issues on the latest release of drupal and Calis.

warning: Invalid argument supplied for foreach() in /home/computer/public_html/modules/opencalais/calais.module on line 351.

I have tried 2.2 and 2.1 both give me the same error.

I am also unable to save any changes in the Node settings.

Hi,

Nothing except all settings that I change reset to the default, like it is read only. It is very confusing, I am new to drupal so I thought it was something I was doing, but after a few days of setting up and configuring drupal, everything else is working but this.

Best Regards,

Hi Frank, I upgraded a Beta test site to the new RDF version Alpha5 without thinking to remove /arc2 RDF is now looking for arc in: rdf/vendor/arc ,needless to say there were lots of errors
I got the same effect, losing the save in the Calais configurations 'node settings', but can save in the 'API'
also lost the 'save changes' in the sites overall 'blocks' I tried to revert to previous stable versions of both RDF and Calais but no joy
I think the damage has been done.
in addition to the same errors as Buggyde. I also got:
Unknown column 'v.prefix' in 'field list' query: SELECT v.prefix, v.uri FROM rdf_namespaces v in /home/public_html/1ana2.com/modules/rdf/rdf.db.inc on line 18.

Regards, Jim

yes I was able to roll back and update to Calais 2.2 with RDF Alpha 5 and Arc from 11/18/2008. simply renaming the 'arc2' folder to 'arc'
I created a blog post, tags were generated as expected. Also the "CalaisDocumentCategory" entity in the Node settings was added, but thats where the weird part comes in. I cant save the newly created category, or any option in the Calais Node Settings. as buggyde reports in #3 above. options can be saved under Calias API Options (searching, distribution, API key) database has All privlegdes, clean 6.9 install. 1 user/admin

---------------------------side note-------------
the inabililtity to save is what caught my eye about this thread. I have 3 production sites, using 2.1 with RDF alpha3. these sites cant save blocks unlessall modules are disabled, I didnt think calais/rdf could be involved. to my knowledge these modules don't do anything with hook_block at all? I have been chasing this saving blocks issue for 2 months, so I am ready to try anything.

I didn't initially realize I was supposed to go to a different screen and complete more configuration steps, so I got this as well on node/add/story:

warning: Invalid argument supplied for foreach() in /Users/webchick/Sites/calais/sites/all/modules/opencalais/calais.module on line 594.

This is coming from:

function calais_get_entity_vocabularies($type = NULL) {
  $all_vocabs = variable_get('calais_vocabulary_names', FALSE);

  if ($type) {
    # this gets set to FALSE since I haven't done this yet.
    $applied_entities = variable_get('calais_applied_entities_global', FALSE);
    if (!variable_get("calais_use_global_{$type}", TRUE)) {
      $applied_entities = variable_get("calais_applied_entities_{$type}", FALSE);
    }

    # line 594.
    foreach ($applied_entities as $entity => $apply_entity) {
      if ($apply_entity) {
        $applied_vocabs[$entity] = $all_vocabs[$entity];
      }
    }
  }
  else {
    $applied_vocabs = $all_vocabs;
  }

  return $applied_vocabs;
}

Is there a particular reason why these variables default to FALSE rather than array()?

Bumping version.

Nah, this was the regular module on a clean 6.x site. I was dinking around with OpenPublish earlier that so I could have a reference example with everything already configured.
