Fork condition

[Kjetil Kilhavn]

Your question was a bit muddy, so Karen's comment may well be the most
applicable here.

If one of the tasks should _always_ be executed and the second task only if
certain values result from that first task you don't want to fork them, you
want a multiple-condition (or just simple condition) step. After the first
task has been executed you check the container value and determine which
path to travel.

If both fork branches should _always_ be executed you set it up with 2
branches required, otherwise with 1.

If indeed you want a fork (both tasks active simultaneously) you can solve
this either by using three flag variables and looping. It get's a bit ugly,
but I think the alternative is to copy the tasks which isn't nice either.
The three flags are of course initial at first.
flag 1: task1_done
flag 2: task2_done
flag 3: we_are_done

Set up your flow as follows.
First you set up a loop which loops until we_are_done is not initial
Inside the loop your fork with two branches and one required is set up. In
each branch you set up a condition. You check whether taskX_done is initial
or not. If it is not initial you go to a branch with a step waiting for
some terminating event. Otherwise you continue and your tasks are sent to
their agents. When the task is executed you set the corresponding flag in a
container operation step, and after the fork ends you set up your
conditions to find out if you need another loop.
If task1_done is not initial and task2_done is not initial you go to a
branch with a container operation and set we_are_done = X
In the other branch you set up another condition check to determine if
we_are_done = X should be set.
And so on.


I said it was going to get ugly......

Are you sure that you want to use a fork?  If you use 2 forks, they will
run simultaneously.

Subject: Fork condition

     Hello,

     Next question,

     This is the first time I want to work with a condition in a fork.

     I have 2 branches. I one is finished, I want to check a value of a
     containerelement. If the containerelement is filled with a certain
     value, the fork other branch should be taken into the process. If the
     containerlement is filled with another value, the second branch is
     important and should be processed.

     Should I fill in "Branches required = 02" and the condition, or should
     the "Branches required = 01" and the condition??
     Or doesn't it work that way??

     Regards,
     Robert
