Directing Activity Joins on Activity Beta

asked Jan 3, 2018 in To be sorted by alevinetx (260 points)

In the original Activity, I can identify nodes using "as".   This doesn't appear to be supported in the new Beta format.

So now I have a diagram where I'd like to force the connection between two paths, but I can't figure out what I'm doing wrong.

In this diagram, I want a line from "BLP4" to "Common 3".  If I remove the 'detach', BLP4 merges back in to its originating trunk.  These are conditional branches, so using fork/join isn't the proper notation.

Thank you !!

Hello,

The new notation is really like code. You cannot do what you want without GOTO. a workaround can be:

@startuml
start
if (RNC) then (NF)
    :NF1;
    :NF2;
    :NF3;
    :Common 1 |
    :Common 2 |
' end NF
    
elseif (BFL) then (BLU) 
    :BLU1;
    :BLU2;
    :BLU3;
    :Common 1 |
    :Common 2 |
    ' end BLU
else (BLP)
    :BLP1;
    :BLP2;
    :BLP3;
    :BLP4;
    'end BLP
endif   
:Common 3 |
stop

I see.  A sacrifice in ideal view, but it provides the linkage desired.   Thank you!

I tried doing this same chart in the original Activity syntax.  I don't know if I was doing something wrong, but the layout was just crazy.  The new one is so clean w/o worrying about items flying around random spots.  I love this tool!!
