Notice: Undefined index: label in function rules_rules_core_data_info_alter()

I also see this message after installing the module. I installed the absolute latest version direct from git.

Unfortunately I get the same error message after activating the module. I installed 7.x-1.0-alpha1.

+1 - same for me, six months later...

I think this might be because the function voting_rules_get_types assumes you have node, user, comment and entity types, however if you dont have all of those enabled (i have comments disabled) then when it calls voting_rules_rules_data_info_alter it creates part of the data for those arrays wether they exist already or not.

Here is a patch that will check if it should alter the data for those entities. cleans up a bit of whitespace too.

update status

Patch works, but should be re-rolled for dev version (if patch applies cleanly to dev version, then version should be changed and RTBC status applied).

Here's the patch worked for 7.x-1.x dev version.
