ADF Basics: Creating Bounded Task Flow Train using af:train component

This post is about using bounded task flow as train
A train presents a whole cycle and it's every stop presents a particular step of cycle
From the docs -

The train component presents a user with a series of stops, each stop representing a step in a multi-step process. The train walks the user through these steps, in a suggested order (the order being dictated by the underlying model). Each step is rendered as a train stop consisting of an image and a textual link indicating if they are in visited, current, unvisited and disabled states. Train can also be rendered in a vertical layout - the default being a horizontal layout. Trains are not rendered on printable pages. 

ADF UI: Using dvt:sunburst to show hierarchical data in ADF

<dvt:sunburst> is one of fancy components to show multi level hierarchical data in form of circular rings in ADF application

It supports drilling up to n-level , consist of dvt:sunburstNode as it's child tag to show level wise detail . Sunburst supports multiple type of animations that makes a better UI
See What docs says -

Sunbursts are used to display hierarchical data across two dimensions, represented by the size and color of the sunburst nodes. The sunburst displays multiple levels of its hierarchy at once, with each ring corresponding to a level of the hierarchy

ADF Basics: Using setActionListener in ADF, Set pageFlowScope parameter without writing code

This post is about using setActionListener tag in ADF, this tag provides a simpler way to set values of other objects and makes use of EL
See What docs says-

The setActionListener tag is a declarative way to allow an action source (<commandButton>, <commandLink>, etc.) to set a value before navigation. It is perhaps most useful in conjunction with the "pageFlowScope" EL scope provided by ADF Faces, as it makes it possible to pass details from one page to another without writing any Java code. This tag can be used both with ADF Faces commands and JSF standard tags. More generally, it can be used with any component at all that implements the standard ActionSource interface.
