The Page Flow determines what actions the application takes and what pages are rendered in the browser under what circumstances. The
Page Flow is based on the industry standard Business Process Execution Language (BPEL) and it is defined in the file with the
.bpel suffix. Each ActiveGrid Application has one and only one
.bpel file.
The Page Flow specifies the
Pages in the application and defines any
Actions that are available to each
Page. Each
Action is essentially a piece of logic that does something and then invokes another
Page. By creating these
Actions and specifying which
Pages are invoked under what circumstances, you define the
Page Flow for your application.
The ActiveGrid Studio provides several predefined Pages that you can add to your application. These
Pages represent the typical roles of
Pages within an application, such as search
Pages for querying the database or list
Pages for listing data from the database. A predefined
Page includes all the associated
Actions for that type of
Page, so you don’t have to create the
Actions by hand.
