All I See is "Array" output on node edit panels

Upping priority. (Don't see me do that every day, do you? :)

I'm having trouble replicating this, though I've seen reports of this more than once.

Can you export the page that's doing this and attach it?

I'm having the same issue too. This happened as I was trying to fix the missing 'Node:Type' in selection rule. And this happens with either 7.x-1.0-rc1 + 1235218-node-edit-context-not-acting-as-node.patch or 7.x-1.x-dev

Wasn't able to reproduce this either, however, found a small notice in case you add an individual form field as a pane (eg, the body field) without a selection rule. The notice is in ctools_entity_form_field_content_type_admin_title().

I'm having the same problem. Here's the current panel export, though it has behaved in the same way with other configurations as well:

$handler = new stdClass();
$handler->disabled = FALSE; /* Edit this to true to make a default handler disabled initially */
$handler->api_version = 1;
$handler->name = 'node_edit_panel_context';
$handler->task = 'node_edit';
$handler->subtask = '';
$handler->handler = 'panel_context';
$handler->weight = -30;
$handler->conf = array(
'title' => 'Plant Edit Panel',
'no_blocks' => 1,
'pipeline' => 'standard',
'css_id' => '',
'css' => '',
'contexts' => array(),
'relationships' => array(),
'access' => array(
'plugins' => array(),
'logic' => 'and',
),
'panels_everywhere_site_template' => 'site_template_panel_context',
);
$display = new panels_display();
$display->layout = 'flexible';
$display->layout_settings = array();
$display->panel_settings = array(
'style_settings' => array(
'default' => NULL,
'center' => NULL,
),
);
$display->cache = array();
$display->title = '';
$display->content = array();
$display->panels = array();
$pane = new stdClass();
$pane->pid = 'new-1';
$pane->panel = 'center';
$pane->type = 'form';
$pane->subtype = 'form';
$pane->shown = TRUE;
$pane->access = array();
$pane->configuration = array(
'context' => 'argument_node_edit_1',
'override_title' => 0,
'override_title_text' => '',
);
$pane->cache = array();
$pane->style = array(
'settings' => NULL,
);
$pane->css = array();
$pane->extras = array();
$pane->position = 0;
$pane->locks = array();
$display->content['new-1'] = $pane;
$display->panels['center'][0] = 'new-1';
$display->hide_title = PANELS_TITLE_FIXED;
$display->title_pane = '0';
$handler->conf['display'] = $display;

Screenshot etc is the same as above

Importing that variant doesn't replicate it. There must be another factor.

Thanks. I've updated ctools, panels and everything else again and it stopped happening.

Excellent!
