Placement of autogenerated code

I'm curious as to how auto generated code is placed.  Looking at the Synergy Test Examples for example.  In the threads tab it shows g_fx_media on FileX as part of the Developer Example Thread.  In the generated code the instantiation/setup code finds it's way into dev_example_thread.c, and an auto generated format call (SF_EL_FX_MediaFormat()) is placed in dev_example_thread_func.  If I do the same thing in a newly created project, the instantiation/setup code finds it's way into common_data.c, and no auto generated format call (SF_EL_FX_MediaFormat()) is placed anywhere.  Why common_data.c, vs. where it was inserted into via. the Thread Tab?  This is with the latest SSP (1.1.3)

Thanks,
