Transition after all <parallel> events are done

[Jeff Chimene]

Hi,

I'm attempting to execute two AJAX requests in parallel. However, the state transition shouldn't occur until both are complete.
The current situation is that the AJAX calls are serial; they can run in parallel. One call will take slightly longer than the other.

What's the best way in SCION to create a gate that won't open until all parallel events are complete?

The specific example is "Add a product to an invoice" & "Create a credit card". These events can run in parallel. However, the "Charge card" call cannot run until these two events are complete.

TIA,

Also, there is a transition that handles the case "no product selected".

IOW, I have
<state id="s0">
 <transition target="s1">
</state>

<state id="s1">
  <parallel>
     <state>
        <if cond="no product">
          <send event="no product" target="s0">
        </if>
     </state>
     <state>
        <if cond="no product">
          <send event="no product" target="s0">
        </if>
     </state>
  </parallel>
  <transition target="s2">
  <transition event="no product" target="s0">
</state>

<state id="s2">

TIA,
