Panels: PHP Fatal error: Unsupported operand types in... date_repeat_field.module on line 519

You may need to clear your caches. If that doesn't work, delete the field from the panel and re-add it. One way or another the panel probably has outdated information stuck in it.

I was trying to add content to a Panel when I got this:

An AJAX HTTP error occurred.
HTTP Result Code: 500
Debugging information follows.
Path: /panels/ajax/editor/add-pane/panel_context%3Anode_view%3A/left/entity_field/node%3Abody/step2

I found the same PHP error message in my error log. Clearing caches did not fix anything, and I don't have a Date field anywhere (yet), only the module enabled. Disabling the Date Repeat Field module cleared the error and I was able to proceed normally. Date Repeat API was left enabled. Reverting to Date 7.x-2.x-dev did not help. Running core 7.10

I have the same error, caches cleared, etc. The $info array passed to date_repeat_field_field_formatter_info_alter() does not have a date_default member when the error occurs. (When trying to add a new panel pane) The attached patch fixes the issue, though I'm not sure if the true problem lies with ctools/panels?

Background info: I'm not using the date_repeat module for anything in particular, I saw the error when trying to add a field collection pane to a node view panels page.

updating status.

Adding Panels to the title to clarify this happens with Panels.

Rerolling the patch.

Committed, thanks!

Confirmed that the patch in #7 is working for me.
