i have decided write form guide renderer instead of using 1 samples. renderer process created observing 1 in samples. after creating renderer, activated , used in process. in livecycle workspace, when try access initialization task, popup error shows up. looking @ logs revealed following error/exception:

the error indicates "the long lived service i3renderer can not invoked synchronously"

your render service needs defined "short lived" process gets called synchronously (as opposed "long lived" process). right click process in work bench , check "properties". if set long lived, change "short lived", save , re-activate.
