activity: cannot write a test following a barrier, except on same line

Question

In the following graph, I cannot move the "if C" to the next line, whereas the doc's "complete example"  has something

similar with 'if "Do redirect?"' that follows a barrier (although the latter is itself inside an if), even without any explicit edge.

Note that the rule for such implicit arrows would be good to describe explicitely.

Also note the orientation of the arrow O --> ==P2==.  Even specifying it as -d-> does not work (somewhat of a separate bug ;)

@startuml

partition P1 {
  (*) --> X
  --> == B1 ==
  --> Y
  ---> == B2 ==
  --> Z
}

partition P2 {
  == B1 ==   -->  if C then
    --> [yes] M
    --> N
  else
    --> N
  endif

  --> O
  --> == B2 ==
}

Also, what if I would like eg. the "if C" and "M" to be in partition P1 but "N" in P2 ?  Or even just have the "if C" outside of any partition, and "M" and "N" still in P2 ?  (I'm still hesitating as to how to express my graph, and I'm feeling a bit limited in options)

Hello,

For the  the orientation of the arrow O --> ==P2==, there is a workaound: I make "longer connections" with:

   ----> Y

   ----> == B2 ==

  ---> Z

 

I try to do the same with the new beta syntax and I have a problem.. P2 is inside P1!!!

 

@startuml

 

partition P1 {

start

:X;

fork

:Y;

fork again

partition P2 {

 if (C) then (yes)

   :M;

 else

 endif

 :N;

 

 :O;

}

endfork

:Z;

}

Hope this helps

Another possible option is to use swimlanes:

@startuml
|P1|
start
:X;
fork
:Y;
fork again
|P2|
if ()
:M;
endif
:N;
:O;
|P1|
end fork
:Z;
