Portlet Factory, Version 6.1.2
About the Application Tree
The Application Tree lists generated elements in the open model selected in the editor area.
You can use the Application Tree in the model editor to navigate to and access a generated element. With an open model having focus in the model editor, click the Application Tree tab to expose the panel and view the WebApp folder and subfolders in which generated elements are listed by type. If the Application Tree tab is not visible, click the arrow icon on the left side of the editor area to shrink the selected panel and expose the Application Tree panel.
The generated elements for a model are displayed in tree form under the WebApp folder. Folders representing element types can be expanded and collapsed. For example, all variables in the WebApp are contained in the Variable folder. The same is true for other types of elements. This organization of generated elements allows you to easily visualize what the WebApp contains and how the WebApp changes during regeneration. For example, you can use the Application Tree to determine what a builder adds to the WebApp.
Click the companion Pages tab to more readily access page and form elements.
For each type of generated element that is selected in the Application Tree, the corresponding code is displayed in the Source panel.
Use the Source panel to examine the related code generated by a builder call or a method.
If you expand a folder in the Application Tree and click on a WebApp object, the builder responsible for creating the object is highlighted in the builder call list. Likewise, if you select a builder call in the Outline view and enable Link with WebApp Tree, the generated elements associated with that builder call are selected in the Application Tree.
The Application Tree operation is closely coupled with the Source view and the Design view.
The Application Tree supports a popup menu that you can use to more readily open builders that created or can modify the selected element.
Note: If you set Show Hidden Object in IBM® WebSphere Portlet Factory Designer preferences, you can see additional objects under the WebApp folder.
Typically, you can see the following folders in the Application Tree:
- Comments
- Displays Comment builder calls. These calls are used to document model construction or segments of builders in the builder call list. They provide a handy means for documenting a model.
- Data Services
- Displays information about generated elements used to access IBM WebSphere Portlet Factory Data Service Layer. This common layer is used to access the back end or external data, and makes it possible to separate the UI from the data. For example, this layer allows you to have one model that is used to access data and a linked model that provides the business logic or user interface (UI) for accessing the data. Objects that might be displayed as Data Services include: Service Calls, SQL Calls, and data access requests made by various View and Form builders.
- Events
- Displays event handler information. (The Event Declaration itself is not displayed.) When an Error Handler builder call is added to a model, its information is displayed in the Source panel. Each event in the WebApp is listed in the Event tree. User defined events (created with an Event Declaration builder) are prefixed with User and displayed only when there is an Event Handler builder present that handles the event. Event Declarations add two methods to the WebApp. These methods show up under the methods folder. The following is a typical event viewer display:
Event: OnError.main Action: showErrorPage- Linked Java Objects
- Displays information about each LJO in the model, including status (persisted for failover) and the public methods within the LJO.
- Methods
- Displays highlighted Java code of selected method. The viewer displays the entire generated methods class, and the selected method is highlighted.
- Pages
- Displays information about each page in the WebApp. The upper panel describes page name status (public) and properties. The lower panel displays page HTML and JSP code and tags. Click on a node (page control) listed under an individual page to jump to the code that implements that node.
Use the Pages panel for more direct access to pages and forms in the model.
- Properties
- Displays information about properties that apply to the overall WebApp. Various builders (for example, the Schema builder and File Chooser builder) create and use WebApp properties.
- Schemas
- Displays the XSD and XML markup defining a schema and the generic structure of elements and attributes (not actual schema data). The upper panel displays schema source and caching information. The lower panel displays schema XSD elements and references.
- Variables
- Displays information about each variable in the WebApp, whether the variable was created manually or automatically by a builder. The upper panel presents information about variable name, status, type, and persistence and properties. For object types, the class name and instantiate method is also listed.
