Why not just do this?:
def index():
form = FORM('blah blah',
INPUT(_type='submit', _value='Apply',_name="apply"),
INPUT(_type='submit', _value='Reset',_name="reset"),
INPUT(_type='submit', _value='Reset
all',_name="resetall"))
if request.vars.apply:
pass #apply was clicked
elif request.vars.reset:
pass #reset was clicked
elif request.vars.resetall:
pass #resetall was clicked
