I'm running into an issue with the api. I use the following call to write to the relationships datatable
$result = civicrm_api3('Relationship', 'create', array( 'sequential' => 1, 'contact_id_a' => $contact_a_id, 'contact_id_b' => $contact_b_id, 'relationship_type_id' => 11,//your specific relationship id ));
from my solution in https://civicrm.stackexchange.com/a/4619/765
However, when I then go to the relationship tab the new entry is not immediately visible. I usually have to force a refresh by changing the relationships per page from 10 to 25 and then the new entry appears. How can I bypass/avoid this problem?
