Link between two activities is established by transitions. Transitions are more than just links between activities. They also describe the condition that must be satisfied in order to get from the source to the target activity (This condition is evaluated during workflow execution).
Typically, you will insert the transitions using TWE's Graph component (although it is possible to do it through the property panels).
Graph component allows you to chose
between conditional and exceptional
transition for the insertion. If you want to
insert a circular transition (a transition from activity to itself), you
can chose the type of the transition you like, and double-click on the
activity within the graph.
If inserting of the transition is not allowed by some rules (i.e. you can't insert two transitions connecting the same activities), you'll be notified.
Here is the table of transition attributes:
Table 4.19. Transition
Name | M/O | Description |
---|---|---|
Condition | O | A Transition condition expression based on workflow relevant data. |
Description | O | Short textual description of the Transition. |
Extended Attributes | O | Optional extensions to meet individual implementation needs. |
Id | M | Used to identify the Transition. |
From | M (for Regulars and Loop End) | Determines the FROM source of a Transition (Activity Identifier). |
To | M | Determines the TO target of a Transition (Activity Identifier). |
Name | O | Text used to identify the Transition. |
Here you can see a dialog for editing Transition attributes:
TWE helps you when you are composing Transition condition - by clicking the arrow right to the text box for entering condition, you get a list of possible variables you can use within condition.
