LTM policies only works with http profile?

Found the problem but no solution to it...

When I add the first rule the following tag is added:

controls { forwarding }
requires { http }
rules {

So "requires { http }" does mean to add a http profile to the VS.

I cannot create any LTM policy with only "require { tcp }" in the UI.

I tried to change the config and used "requires { tcp }", the following error shows up:

010717bc:3: Policy '/Common/pol_AQ_8137', rule 'rule_AQ'; event 'request' is not available, add the appropriate profile type as required.
Unexpected Error: Validating configuration process failed.
