Adding an action to a transition

An action is an activity that is executed on a transition.

To add an action to a transition, proceed as follows:

Procedure

1. On the canvas, select and hover over the transition that you want to modify.

2. In the action bar that appears, click the action icon as shown in this image.

   

3. In the Properties area, click the Details tab.

4. Select the Implementation. You have the following choices:

   Option	Description
   Visual	Choose this to use the visual snippet editor to graphically compose Java™ code.
   Java	Choose this to write the Java code yourself.
   Invoke	Choose this to invoke an operation on a reference.

   When a transition is triggered by a call event, the input and output parameters of the operation are available to the action so that the action can set the output parameters that are sent in reply to the operation after the action completes. When a call event occurs, its input parameters are copied to the output parameters of the operation so these variables must have unique names so that they don't conflict with those of other operations. As a result, for each input parameter of an operation, a variable of the appropriate type is created with a name of opName_Input_parmName, and for each output parameter, a variable named opName_Output_parmName is created. These variables are only available to the action of the transition that is triggered by that operation.

Results

Your newly created action will appear on the canvas on top of the transition that it is associated with.
