### 13.4.6. Defining and Editing Process Transitions

Actions that are associated with process transitions are presented in the following sections.

Topics in this section include:

- Inserting Transitions

- Editing Transitions

- Renaming Transitions

- Deleting Transitions

#### 13.4.6.1. Inserting Transitions

Although transitions are created automatically when you are building a process template, there may be situations where you need to manually insert a transition between two nodes. Note that the order in which you select nodes determines the direction of the transition arrow.

To insert a transition:

1. Select the node where you want the transition to start.

2. Shift+click or Ctrl+click to select the node where you want the transition to end.

3. Right-click and select Insert Transition, or click on the toolbar.

#### 13.4.6.2. Editing Transitions

Once a transition has been inserted in your diagram you can edit its name and specify a trigger expression if needed.

To edit a transition:

1. Double-click the transition in the diagram. This opens the Edit Transition dialog box.

   Figure 13.19: Edit Transition Dialog Box for a Process

2. Modify the transition settings and click OK.

   Name

     The name of the transition. There are no restrictions on the characters you can use in a transition name.

   Source

     The name of the node that the transition originates from. This property is read-only and the value cannot be edited.

   Destination

     The name of the node that the transition terminates at. This property is read-only and the value cannot be edited.

   Trigger expression

     The condition under which the transition is triggered (or traversed) in a process. If the trigger expression is not specified then the transition is always traversed. A sample trigger expression is shown in Figure 13.19: Edit Transition Dialog Box for a Process. See Using Expressions in Process Elements for syntax you can use in trigger expressions.

     When a transition has a trigger expression, a diamond is displayed on the transition line:

     Note: In an iteration block, the trigger expression will be ignored in the transition between the iteration node and the first node, and in the transition between the last node and the iteration node.

#### 13.4.6.3. Renaming Transitions

To rename a transition, right-click it in the diagram, then select Rename from the context menu. You can then edit the name in the Rename dialog box.

#### 13.4.6.4. Deleting Transitions

To delete a transition in a process diagram, select it in the diagram and either press the [Delete] key on your keyboard or right-click and select Delete from the context menu.
