Working with Navigation Flows - Oracle ADF 11gR2 Development Beginner's Guide - page 182

Control flow
To navigate between aciviies inside the task low, we use the control low. The control low
will connect the acivity using the arrows in the diagram view. The control low will have
three secions deined, namely, from-activity , to-activity , and from-outcome .
from-activity : This represents the acivity from which the control low iniiates.
to-activity : This represents the acivity to which the control low is mapped.
from-outcome : This represents the acivity from which the control low is directed.
This is the outcome from from-activity .
Wild card
Wild card acivity can be added to bounded or to unbounded task lows. We use the wild
card acivity if we want to navigate the control low from any outcome. The outcome and
the low can be anything to reach an acivity targeted in the task low. For example, in the
next screenshot, the control flow will navigate to createDepartment from any outcome,
which starts with foo and any number of characters after that.
Task flow options
The task low opions are available to support diferent coniguraions for the task low.
The opions can be changed from the Overview tab or from the property inspector by
selecing the task low. Let us see the opions available for the task lows in detail.
General
The opions available in this category are as follows:
Task Flow ID : This is a unique task low ID used to idenify the task low when
used within another task low within an applicaion, or when the task low is
included in a library for reuse.
