Commons radioactivity throws notice when some nodes are created

Looks reasonable to me.

setting back to active....sorry....

I have applied the patch but I just now still got the error message when creating a node.
Only difference is now the error message is for line 132, which is where the reference is now after the patch was applied.

Notice: Undefined index: und in commons_radioactivity_incident_node() (line 132 of /usr/www/users/incite/incite7/profiles/commons/modules/contrib/commons_radioactivity/commons_radioactivity.module).

@WebSinPat The patch has been committed and is in Commons 7.x-3.4; you shouldn't have to apply it.

Can you confirm the version of Commons you are using?

Ah sorry @Devin Carlson, I forgot to specify I am still on commons 3.3.
Are there other changes other than what's in the patch in #1 needed for this fix?

Even with 3.4 I'm still getting this notice for some nodes that do have the field, but without a value.

Changing the line from:

<?php
if (!isset($node->field_radioactivity)) {
?>

to

<?php
if (empty($node->field_radioactivity)) {
?>

fixes the issue.

Here's a patch.

I am running Commons 7.x-3.17. It is a new install, no upgrades. I am suddenly getting this same error message.

Notice: Undefined index: und in commons_radioactivity_incident_node() (line 104 of /var/www/drupal4/profiles/commons/modules/commons/commons_radioactivity/commons_radioactivity.module).

Not sure where it came from or why.

I can confirm issue occurs on Commons 7.x-3.17 on our existing system upgraded a couple of weeks ago. This happens when adding a new node (group content) to a group. The field_radioactivity key is set in the group node object (checked on line 99), but it points to an empty array so field_radioactivity[LANGUAGE_NONE] returns the message shown.

Backtracking up the call stack, I'm finding that the call to node_load_multiple() in function commons_radioactivity_groups_incident_groups() returns group objects with an empty array for field_radioactivity. There are data rows in the DB with values for that group. All other fields appear to be correctly populated.

What's special about field_radioactivity on a group node?

I am also getting this message when trying to create a post.

I am on a fresh install of 7.x-3.17.

Notice: Undefined index: und in commons_radioactivity_incident_node() (line 104 of profiles/commons/modules/commons/commons_radioactivity/commons_radioactivity.module).

I am on a fresh install of 7.x-3.18 and getting the same error message occasionally. Doesn't seem to be easily reproduceable.

How does one re-open a closed issue.

I seem to be getting an increasing number of messages per

"Undefined index: und in commons_radioactivity_incident_node() (line 104"

of late, and that's in the latest release 3.20 of Commons.

I am also getting those error :/

I have this issue on Commons 7.3.20 too, warning appear because radioactivity field is empty.
Here's a patch.

I checked that patch : 2105133-radioactivity-notice-19.patch on Commons 3.17 and it worked at least once.
# cd /site directory/profiles/commons/
# patch -p1 < /path to patch directory/2105133-radioactivity-notice-19.patch
patching file modules/commons/commons_radioactivity/commons_radioactivity.module

When I created a new post, I had no more error message.

Patch in #19 worked for me to.
Thanks @sdstyles .

Restored the fix from #9.
