How to use Avalon-MM Master BFM?

Thank you, your tutorial is great, I have seen it already and learned a lot. There are few tutorials for single BFM, but nothing for two or more. Even in Avalon Verification IP Suite User Guide is described simulation with only one BFM.

Here is my task. Without commented push commands it works fine. Now it produces already mentioned error.

task master_set_and_push_command;

input Request_t request;

input [`AV_ADDRESS_W-1:0] addr;

input [`AV_DATA_W-1:0] data;

input [`AV_NUMSYMBOLS-1:0] byte_enable;

input [`AV_DATA_W-1:0] idle;

input [31:0] init_latency;

begin

if (request == REQ_WRITE)
