[NOT A BUG] Hard crash when a category node is set to have a page node as parent


Active Member
I have a page node which I use to display specific categories which are not shown on the standard forum index. To have navigation line up properly with the breadcrumb trail being correct, I like to have the page node set as the parent node of those categories. However, when I set a page node as parent node to a category, I get a white page with this error on the frontend:
An exception occurred: [Error] Call to undefined method XF\Entity\Node::setTlgGroupEntity() in src/addons/Truonglv/Groups/Repository/Group.php on line 136

With the social groups addon disabled, I don't receive any error with that configuration.

This is with Social Groups 2.1.4 in XenForo v2.1.6 Patch 1.

Hmm, I've now tried to trigger this error again to provide a step-by-step way for you to reproduce it, and am unable to get it to trigger again. I now have categories set to have a page node as parent and hidden from the standard node list, with no error.
Possibly this is from the upgrade to XenForo 2.1.7, as I can't think of anything else which might have substantially changed since I was getting this error. Whatever the reason, it's not happening any longer, so this report can be closed.
