How should i code a "forever loop" Activity Diagram (beta)?

Question

I want to describe a task that, after initialization, loops forever.

I tried something like:

start
:initialize;
while (Timer interrupt)
    :do something;
endwhile

This somewhat works, but also draws an ugly (and useless) arrow representing the (nonexistent) exit from loop.

    start
    :initialize;
    repeat
        :wait Timer interrupt
        :do something;
    repeat while

This doesn't have the arrow problem, but it's less graphically nice as it requires a useless junction.

Is there a way around?

Answer 1

You cannot avoid the junctions at present but draw to express the stuff if you want while condition on top, repeat would look like a do while

start
    :initialize;
    repeat
    while(wait for interrupt) is (interrupt)
    :do something;
    endwhile (no interrupt)
    repeat while
