State change single-action buttons misplaced on node edit form

The above was in the node view mode.

In the edit screen, the buttons are at the top of the edit screen while the comment box is at the bottom.

Moving to extensions

This takes care of my situation:

  function _workflow_extensions_replace_with_buttons(&$form, $workflow_name) {
    $current_sid = $form['workflow'][$workflow_name]['#default_value'];
    $current_state_name = workflow_get_workflow_states_by_sid($current_sid)->state;
  
    // We need a node-context for token replacement. When on the Workflow tab
    // form, the node object will already have been loaded on the form.
    // When creating content (node/add/<type>) we only have limited data. In
    // the remaining cases we load the node from the cache based on the nid
    // found on the form.
    $form_id = $form['form_id']['#value'];
    if (strpos($form_id, 'workflow_tab_form') === 0) {
      $node = $form['node']['#value'];
    }
    elseif (is_numeric($nid = $form['nid']['#value'])) {
      $node = node_load($nid);
    }
    else { // Creating new content, nid not yet known
      $node = $form['#node'];
    }
    $states = $form['workflow'][$workflow_name]['#options'];
    $submit_handlers = _workflow_extensions_assign_handlers($form);
+    $form['workflow']['buttons'] = array('#prefix' => '<div class="workflow-buttons">', '#suffix' => '</div>');
  
    foreach ($states as $sid => $to_state_name) {
      if ($sid != $current_sid) {
        // Create button for transition from current_sid to destination state.
        $button = array();
        $button['#value'] = workflow_extensions_get_transition_label($form['#wf']->wid, $current_state_name, workflow_get_workflow_states_by_sid($sid)->state, $node);
        $button['#type'] = 'submit';
        $button['#to_state'] = $sid;
        if (isset($form['buttons']['submit']['#weight'])) { // node form
          $button['#weight'] = $form['buttons']['submit']['#weight'] + 1;
        }
        elseif (isset($form['submit']['#weight'])) { // comment form
          $button['#weight'] = $form['submit']['#weight'];
        }
        $button['#submit'] = $submit_handlers;
-        $form['buttons']["submit_to_$to_state_name"] = $button;
+        $form['workflow']['buttons']["submit_to_$to_state_name"] = $button;
      }
    }
    // Get rid of workflow radio buttons that live inside the fieldset
    unset($form['workflow'][$workflow_name]);
    // If after this the fieldset is empty, remove it altogher
    if (!isset($form['workflow']['workflow_scheduled']) &&
      (!isset($form['workflow']['workflow_comment']) || $form['workflow']['workflow_comment']['#type'] == 'hidden')) {
      unset($form['workflow']);
    }
    // With the existing Save button now impotent to submit a workflow
    // transition, we can re-purpose it for saving all other edits to the
    // node without changing the workflow state.
    // This does not make sense for the Workflow tab form though, as there is
    // nothing to save but a state change. In this case we simply remove the
    // Save button.
    if ($form_id == 'comment_form') {
      $form['actions']['submit'] = $form['submit']; // ???
      $form['actions']['submit']['#submit'] = $form['#submit'];
      $form['actions']['submit']['#weight']--; // left-most
    }
    if (strpos($form_id, 'workflow_tab_form') !== 0 && ($label = variable_get('workflow_extensions_default_save_button_label', ''))) {
      $form['actions']['submit']['#value'] = workflow_extensions_replace_state_name_tokens($label, $current_state_name);
    }
    unset($form['submit']);    // remove submit button...
    //unset($form['#submit']); // ... but don't remove handler, #1097328: Menu changes are not saved
  }

This is not a problem with the code proposed in #1884630: State update conflicts with Comment form.

That issue has been fixed.

I would recommend that you download the -dev version of Workflow that will roll out in a few minutes.

Line 362: $form['workflow']['buttons']["submit_to_$to_state_name"] = $button;
