i'm looping on following: a might equal task, wash_dishes or play_piano exec("%a = production(precondition({%s}),action({%s},{%s}))" %(a, precondition, stop, start)) list_a.append(a) expect: list_a = [wash_dishes, play_piano] (where wash_dishes production created above, not "wash_dishes") a holds string (parsed json), , want add value of a (as variable) list. thanks in advance! hope made sense! use dictionary. in exec() code, put quotes around place variable substituted, use value string. symboltable = {} exec("symboltable['%s'] = production(precondition({%s}),action({%s},{%s}))" %(a, precondition, stop, start)) list_a.append(symboltable[a])

i'm trying update process variable after starting process when starting activiti, pass random string value variable need update variable value afterwards. system.out.println(runtimeservice.getvariables(executionid)); runtimeservice.setvariable(executionid, varname, varvalue); system.out.println(runtimeservice.getvariables(executionid)); and output variableone : "randomvalue" variableone : "updatedvalue" but when documentation of task documentation the variable value ${variableone} i output the variable value randomvalue instead of the variable value updatedvalue the problem execution id not same process instance id. need update variable against process instance id rather execution id. cheers, greg

i've read other questions response aren't helping me much. once again, i'm not developer wood worker trying make far complicated own brain. i work on pic alignment 4 bytes, structures define attribute ((packed)). i've found way uses malloc , str/mem-cpy, methods aren't safe interrupt, or malloc shouldn't using @ (cf. previous question) said structure contains 16 unsigned char, 1 s16 (2 bytes) et 3 s32 (4 bytes), 30 bytes long, 4bytes alignement making 32bytes long.
