Some of the complex and advanced features of the task flow are discussed in the following sections:
Trains: One of the reasons for using a task flow is that an ADF task flow allows the user to add trains to a web application, as shown in the following screenshot:
Each of the page fragments is added as a train stop and is linearly linked to provide a wizard-like feature in the web page. Checking the
trainoption for the task flow will enable the task flow to support train stops. One common expression used with the train is as follows:#{controllerContext.currentViewPort.taskFlowContext.trainModel.getNext}" #{controllerContext.currentViewPort.taskFlowContext.trainModel.getPrevious}"Template: The task flow template is another useful feature that will enable the task flow to behave like a template, to add and support other task flows. A base task flow template is created for a repeated process and then it is reused by the consuming task flow to build a complex task flow.
