Can you describe how this problem occurs? I'm not experiencing it with the stock installation of either 3.x or 4.x. I'm guessing the problem is that it's being called with a NULL value to begin with, which shouldn't be happening.

We are running webform_profile in addition to webform (not sure if that contributes) and I am seeing this during node access rebuild.

I'm experimenting the same problem with _webform_components_tree_flatten: Invalid argument supplied for foreach() a xxx/drupal/sites/all/modules/webform/webform.module a la línia 3267

I'm using:

Webform 6.x-3.18
Form builder 6.x-1.1
Options element 6.x-1.7
jQuery UI 6.x-1.5

I'm not experiencing this issue either. @oriol_e9g are you using webform_profile as @pdrake was, and does the patch in #2 help?

We need instructions on how to reproduce this issue. It doesn't seem to be apparent with stock installations of Webform/Options Element/Form Builder.

I'm not using webform_profile, I need more research to find the bug or the steps to reproduce the bug:/

I'm closing this. It's been 2 years with no reproduction instructions. I would think that if this happened in the course of normal operation, we'd be hearing more complaints by now. Please re-open if you can reproduce it in the current 7.x-4.x-dev (which is currently beteen rc3 and the upcoming rc4).
