Can't import template with taxonomy required

Thanks for a great catch! The fix I am considering is to clone the node attributes of the template in the target spreadsheet. This should then work transparently for taxonomies and any other node attribute. I unfortunately won't be able to work on this before next week.

I just committed a fix to this issue. I had to design a generic fix, not one that would just work for taxonomies. Here's how I did it:

When the module is about to create a new Sheetnode out of a template, it fires a hook_sheetnode_template_alter call to allow any 3rd party module to extend the node creation parameters with whatever data is required. This way, Sheetnode doesn't have to guess which fields are required and which aren't.

I tested this fix with a required vocabulary on Sheetnodes, as in the original report. Here's my code to supply the required taxonomy terms to the node about to be created, based on a new template field 'vid' that holds a reference to the node from which this template was created. My code just copies all terms from that original node into the new node's form_state.

<?php
function d6_sheetnode_template_alter(&$form_state_node, $template, $form, $form_state) {
  $original = node_load(array('vid' => $template->vid));
  if (is_object($original)) {
    foreach ($original->taxonomy as $vid => $term) {
      if (is_numeric($vid) && isset($term->tid)) {
        $form_state_node['values']['taxonomy'][$vid] = array($term->tid => $term->tid);
      } 
    }
  } 
}

?>

Note that this code is for illustration only. In particular, multiple-valued taxonomies and tags will not work correctly.

Please test this fix 12 hours from now. You will need to run a database update.

I also faced this problem but when I try to import a excel file. The error message was not very clear and it only says "sheetnode field is required".
When I unmarked the taxonomy term as not required, I was able to import the file.

I adapted the solution above to all import mechanisms, with a little modification. To use it, you need to implement hook_sheetnode_alter(&$form_state_node, $form, $form_state) as described in #3 above. The different is that I changed the hook name and removed the $template parameter.

Please download the latest dev release to try it (12 hours from now) and let me know if it works for you!
