Choice Routing

In cases where you need to have multiple process flow paths for separate conditions based on a single variable (or literal/script); you can use the Choice ActionStep . In these situations you could us multiple IfThen steps, but the Choice step helps give visual order to the process.

NOTE: The Choice step acts much like the switch operation common in many modern programming languages.

Walkthrough

Download Saflet Used in this Walkthrough


For this walkthrough; you will need to be connected to a SafiServer (see Connection to SafiServer from SafiWorkshop). You will also need to create a Project/Saflet with the Custom Initiator selected as the starting initiator (See: Creating a Project and Saflet)

First, add a Local variable named myActionVar of the type Text and assign it a default value of A:



Next add the following ActionSteps to your work area:

• (1) Choice (found under Logic)
• (3) DebugLog

And connect them like this:



We'll connect the other two DebugLog steps later

Double-click the Choice step to open the edit dialog and set the Value field to the myActionVar (press the edit button(...) and select the variable):



Add a CaseItem by pressing the plus (+) button to the right of the Choices box. In the script tab enter the following:

"A";

Press OK and repeat the process entering the following in the script tab:

"B";

After pressing OK to add; you should the following:



And when you press OK; your workspace should look like this (the Choice step now has two more exit paths):

Now connect the newly formed exit paths to the top two DebugLog steps. Also, set the Message fields in DebugLog steps with the following script (top to bottom):

"the A path was taken";

"the B path was taken";

"the default path was taken";

Save and Publish the Saflet and set it off using the Custom Initiator Launcher



Your Console should look like this:



You can debug this Saflet to get a more granular view of whats happening. You can also change the Initial Value of the myActionVar variable to see the different paths (i.e. try changing it to "B").
