Application Service stats not yet reported in iWorkflow L4-L7 services deployed

Hi,

I have deployed an iApp services (by the scratch template's implementation) through Workflow(2.1.0). On the LTM target I get it implemented, with virtual server in status GREEN, but on iWorkflow from the General Properties of this service, I get this message "Application Service stats not yet reported."

If i use an "working" template provided with F5(), the message is Application Service is healthy.

Reading the code of working template, I saw the following lines could solve it:

iapp_conf create sys icall script publish_stats definition \{ $icall_script_src \}
iapp_conf create sys icall handler periodic publish_stats interval 60 script publish_stats

Are same references around?
