node type visibility settings not respected with panels

Same here.

Nope, I didn't get any such issue.
I downloaded both modules sharebar[7.x-1.x-dev] & panels[7.x-3.2] in fresh drupal 7 installation & tried creating mini panel, & panel node, but couldn't regenerate issue.
It would be nice if you can tell more information in terms of versions used, what exactly did you do? etc which can help me to reproduce it.

Thanks

I'm not sure about the first person, but I am not creating a Panel node using the Panels module. I am using Panels to override the node template for a particular content type.

I am on the latest stable Panels/CTools versions like you are testing above.

Yes, I confirmed this issue too. I have the same configuration with @noslokire, using Panels to override node template. The error is the same: Notice: Undefined index: nodes in sharebar_preprocess_region() (line 120 of ...

Look at the attachment, there is no 'nodes' index in $variables['elements']['system_main'] when using Panels to override node template.

I think the error comes from the code to obtain $node->type. The code assumes the node type can always be obtained from the $variables['elements']['system_main']['nodes'], but when using Panels to override node template, the variable is not available.

How about check it first, if available, we can take it from $variables. Otherwise, I think we can use node_load() function to get node type. Using node_load() does incur additional overhead, but it's the most intuitive source to obtain node type.

This is just my code suggestion, I'd be glad if we can discuss it here:

/**
 * Get type of a node, called from sharebar_preprocess_region()
 */
function _sharebar_get_node_type($variables) {
  $node_type = '';
  if ((arg(0) == 'node' && is_numeric(arg(1)) && arg(2) == '')) {
    if (array_key_exists('nodes', $variables['elements']['system_main'])) {
      $node_type = $variables['elements']['system_main']['nodes'][arg(1)]['#node']->type;
    } else {
      $node = node_load(arg(1));
      $node_type = $node->type;
    }
  }
  return $node_type;
}

/**
 * Preprocess variables for region.tpl.php
 */
function sharebar_preprocess_region(&$variables) {
  if ($variables['region'] == 'content') {
    if (arg(0) != 'admin') {            
      if ((arg(0) == 'node' && is_numeric(arg(1)) && arg(2) == '' && 
        variable_get('sharebar_bar_posts_' . _sharebar_get_node_type($variables) . '_enabled', TRUE)) 
        || (!(arg(0) == 'node' and is_numeric(arg(1))) and arg(1) != 'add' && arg(2) != 'edit' && arg(3) != 'edit' 
        && variable_get('sharebar_bar_pages_enabled', TRUE))) {
        // ...

ganagus,
Thanks, would you like to throw a patch for it?

I can confirm the bug, and that the code in #5 fixes the issue. I went ahead and rolled a patch, attaching here.

#7: sharebar-panels_compatibility-1617110-7.patch queued for re-testing.

Yes, I confirmed this issue too. I am using Panels to override node template. The error is the same: Notice: Undefined index: nodes in sharebar_preprocess_region() (line 120 of ..

Here is another version of the patch, I applied this patch and I tested several times. I don't see the error anymore.

Applied patch with some changes. Let's hope it doesn't break unknowns. Thanks much guys (:
