The stack trace is showing it originates from 1112 of webform.conditionals.inc

This may be a bit better solution, see patch.

Here's what happens:

When webform_client_form generates the form, it sets the theme to webform_form.
That causes template_preprocess_webform_form to be called.
That function calls webform_conditional_prepare_javascript.
That function calls webform_component_parent_keys.

But webform_client_form also uses form_load_include to include webform.components.inc, so the patch in #2 should not be necessary.

I'm guessing that something happened to the form by way of a form_alter or perhaps theme that is causing the form_load_include to not load, or perhaps some ajax / jQuery request. You will need to debug to see how this is possible.

While it is possible that webform has a bug here, I'd say it is extremely unlikely. A call to an undefined function is fatal and people would be seeing errors and we'd have lots of reports. Something is different about your installation.

If you verify that this can happen on a clean installation, please change the status back to Bug and re-open as Active. Thanks.

In my case it could be authcache or js module that may be altering things in a funky way... my eye is on authcache. *squints*

A stack trace would give some clues, maybe. If no one is complaining, maybe its an ajax error where you wouldn't see the failure??

It's the only error showing up in my watchdog at the moment so I'm trying to knock it out.

Here's the callstack from new relic:

I am getting this error as well, but during use of Rules.

i have a webform node and need to use it's title within a Rule.
* If I invoke the data through 'Data selection' everything works as expected.
* If invoke the data though 'Direct input mode' and use the token [webform:title] the error occurs.

In comment #3 Dan says "But webform_client_form also uses form_load_include to include webform.components.inc, so the patch in #2 should not be necessary."

My error message says
Fatal error: Call to undefined function webform_component_parent_keys() in ...drupal/sites/all/modules/webform_charts/webform_charts.tokens.inc on line 41

I assume that this call do not invoke form_load__include thus the webform_component_parent_keys is never defined.
