Example Implementation for InfoPageComponent

This example can be viewed in the Windchill product by navigating to Customization > Component Catalog > Information Page. The Customization tab is hidden out-of-the-box but can be enabled via the “Client Customization” preference available in Site->Utilities->Preferences Manager.

This example shows an info page for an object of the new type “Carambola.”. The Carambola object type is a simple Java class with an icon and various attributes. The example illustrates how to:

• create a set of tabs

• define a tab customization menu (tab actions)

• define an action dropdown menu

• display status glyphs next to the object name

• add a help topic

• construct a custom VisualizationDelegate

• use a custom view JSP that adds toggle buttons for commonspace/ workspace and a Go to Latest link.

Two of the tabs displayed on the info page illustrate what happens when the server encounters errors when producing a page. The tab “Error Page With Generic Exception” shows how exception messages are displayed when Java or Scriptlet code executed on a JSP page throws an exception. The tab “404 error” shows how a HTTP 404 response code is displayed when the JSP page specified in an action cannot be found. The action “Action Has Invalid Onclick” in the Actions menu illustrates the message that is provided when the JavaScript mentioned in the “onclick” attribute of an action command sub tag is invalid.

The action “Action Has Complex Onclick” illustrates another action with an invalid “onclick” attribute. Onclick attributes must contain a single JavaScript function call. In this case, the onclick attribute has multiple function calls. The action framework wraps the multiple statements in one function call to prevent the page display from aborting.

The panels and tables available for display on the info page tabs via the Customize link are ones created for other examples in the Customization tab, such as the Attribute Panel, Property Panel, and Table examples.

Files Used in this Example

File	Description
Carambola.jar Source code examples are in the Carambola-java.jar file in the <Windchill>\Windchill\srclib\wnc directory.	This is the “Carambola” object class.
CarambolaVisualizationDelegate.java Source code examples are in the Carambola-java.jar file in the <Windchill>\Windchill\srclib\wnc directory.	This is the delegate that creates the content for the VisualizationComponent on the page.
CarambolaInfoBuilder.java Source code examples are in the Carambola-java.jar file in the <Windchill>\Windchill\srclib\wnc directory.	This is the info page builder class for object type “Carambola”.
CarambolaVizAndAttrBuilder.java Source code examples are in the Carambola-java.jar file in the <Windchill>\Windchill\srclib\wnc directory.	This is the builder for the Visualization and Attributes panel. You do not have to write a builder for this panel. Such a builder is required only for this example because the “Carambola” object type is not a type that is exposed in the Type Manager.
carambolaInfoPage.jsp Source code examples are in the Carambola-java.jar file in the <Windchill>\Windchill\srclib\wnc directory.	This is the view (JSP) for the page with JavaScript to produce toggle buttons and Go to Latest link.
<Windchill>\Windchill\codebase\com\ptc\carambola\carambola.service.properties.xconf	This is the VisualizationDelegate service property.
