Drawing flows in the flow editor

Development tools : Transaction editor : Drawing flows in the flow editor

A flow performs a specific business process based on multiple states. A flow must:

▪ start with only one initial state

▪ end with one or multiple final states

▪ have any other states with correct properties and events

▪ have proper transitions connecting these states assigned. Each transition is assigned with each event.

For more information on flows, see Flows.

To draw a flow in transaction editor

1 Create a UDTT flow file and open it using UDTT Transaction Editor.

2 In the Transaction editor, click the Flow tab.

In the Palette pane, there are State and Transition listed.

3 Add the state you want: see Creating initial state.

To add a Page state, Operation state, or SubFlow state, you can drag the referenced file from the explorer view (in UDTT Perspective, UDTT Project Explorer; in Java EE perspective, Enterprise Explorer) to the Editing area.

4 Set the properties of each state for more usability.

5 Connect the states using transitions.

6 To navigate the element in the Editing area by using the keyboard, use Ctrl+Arrow keys. The element will be focused as if it is hovered over by the mouse, instead of selected as if it is clicked by the mouse. Press Ctrl+Shift+Spacebar or Ctrl+Spacebar to switch between the two status.

7 You can also set the transition type to “do nothing”. This means that the parent page at the client browser is not re-rendered; any changes on the server side are not updated or refreshed on the client side. Use “do nothing” if the transition points to the parent page state, for example, after some operation state.
