Hi Guys,

I've confused myself or reached that point in the night where all i can do is scratch my head - So I'm hoping someone can help.

I've created a hook around the default comment system in a plugin and would like to now add to the river anytime someone comments on the primary/main object in the plugin...

in the add.php action for adding a comment I have the following stored;

        $entity_guid = (int) get_input('entity_guid');

// get other input info from the new comment form....then

                $newcomment = new ElggObject();  
                $newcomment->subtype = "comment";  
                $newcomment->owner_guid = $_SESSION['user']->getGUID();  
                $newcomment->container_guid = $_SESSION['user']->getGUID();
                $newcomment->access_id = 1;
                $newcomment->parent_guid = $entity_guid;

                $newcomment->description = $comment_desc;         
                $newcomment->save();

then below the line where a successful system msg is called to let the user know their comment post was successful....I have;

add_to_river('river/object/myplugin/annotate','comment',$_SESSION['user']->guid, $newcomment->parent_guid);

have also tried;

add_to_river('river/object/myplugin/annotate','comment',$_SESSION['user']->guid, $entity_guid);

But when accessing the river after successfully posting a comment

the river/object/myplugin/annotate.php returns an error stating that

Fatal Error: Call to a member function getSubject() on a non-object in line 11 of blah blah annotate.php

which is;

$performed_by = $statement->getSubject();

Basically I'm not sure if the $subject_guid and/or $object_guid are being appropriately set.

Ideally if someone comments on an object in the plugin a link to that object (parent_guid?) would be the preference.

Any help greatly appreciated.

Thanks,

Jimbo
