Ctools context and panel page for webform submission patch

Looks good to me

I don't regularly use Panels, so I'm not super-keen on including this in the main module.

This bit of code seems rather hackish, shouldn't there be a way to get information without using arg() here? And combining everything into $data->{$component['form_key']} won't work because form keys are not unique, they're allowed to duplicate as long as they're on different pages or fieldsets.

+    $nid = arg(1);
+    $sid = arg(3);
+
+    $submission = webform_get_submission($nid, $sid);
+    $node = node_load($nid);
+    $components = $node->webform['components'];
+    $page_count = 1;
+    _webform_components_tree_build($components, $component_tree, 0, $page_count);
+
+    $data = new stdClass();
+
+    // Make sure at least one field is available
+    if (isset($component_tree['children'])) {
+      // Recursively add components to the form.
+      foreach ($component_tree['children'] as $cid => $component) {
+        $data->{$component['form_key']} = $submission->data[$cid]['value'][0];
+      }
+    }
+    $data->nid = $nid;
+    $data->sid = $sid;

This kind of use of GLOBALs and variables isn't going to fly either:

+function webform_webform_submission_view_enable($cache, $status) {
+  variable_set('webform_webform_submission_view_disabled', $status);
+
+  // Set a global flag so that the menu routine knows it needs
+  // to set a message if enabling cannot be done.
+  if (!$status) {
+    $GLOBALS['webform_webform_submission_view_disabled'] = TRUE;
+  }
+}

I've been using Panels more regularly recently, but from the looks of this patch, this isn't code that I'd be comfortable maintaining within the project. I don't really understand what this code is doing (possibly due to Panels/Page Manager rather than this code itself) so I'd rather see this live as a stand-alone project for the time being. Even though I'm using Panels on almost every project these days, and I use Webform on every project, the need to combine both of them isn't a scenario I've encountered. So I hope I'm not over-extrapolating my individual experience here, but for me the maintenance cost compared to the reward aren't in balance.

I'm open to reconsideration. But this doesn't look like a good fit for the main project to me.
