Web Component Guide

Core Concepts

Certain core concepts find application throughout the Web Component Framework.

These core concepts are:

• Modules

• Observations

• Context

• Parameters

• On Null Values

• Renderers

• Default Values

• Data Sources, Data Types, and Data Objects

• Paths

Modules

The default Web Component Framework definitions (views, queries, renderers, tasks,

icons, files, types, and units) in vFoglight are organized onto modules and sub-modules.

A module contains a collection of related definitions. With the proper privileges you can

add entities to any of the existing modules, and users with access to the Definitions

choice (in the navigation panel under Dashboards > Configuration) can create entities

in their own modules, which you can save by exporting them to a file. Also, you can

import modules that have been created on another vFoglight server.

Importing and Exporting Modules

For information on importing and exporting modules, see the Command-Line Reference

Guide.

Validating Modules

You can validate your module and check all the definitions within it for errors or

warnings. This is useful for catching errors that might have crept in through hand coding

or prior incompatibilities in the WCF tooling that allowed poorly-configured views to

be saved. This functionality can be invoked from the module’s menu.
