Web Component Tutorial

When you view the All Hosts dashboard, you may notice that the area assigned to

the table may not be wide enough to show all of its columns without clipping the

rightmost column. If this happens, edit All Hosts by choosing the Layout tab,

selecting the rectangle for Monitored Hosts, and dragging its right edge.

Adding a Dependent Page

This task introduces the notion of Context. A required context input, which declares it

as essential for the operation of the drilldown page, is the kind we will use in this

example. Contexts are entities that have a data type, so a context must first be declared,

much like a variable in a programming language, by giving it a key, which is the name

by which it can be referenced, and a type, which is chosen from a list of available types.

You’ll see in this example how a value is assigned to a named context so that it can be

passed to the drilldown page via a flow.

Overview

Adding a dependent page that relies on a context supplied by the parent page involves

these steps:

• Create a dependent page.

• Define a Context Input.

• Define a flow from the parent page to the dependent page.

• Set a Flow Context Mapping on the table row that will supply the context to the

dependent page.

• Insert the desired component on the dependent page and specify the same context

in the component that needs it.

Adding a Context-Sensitive Dependent Page for the Table of

Hosts

In the first tutorial we chose a fixed layout container because it has simple properties

that are easy to adjust. When, in this tutorial, we needed to widen the table it contains, it

was a simple matter of dragging the table’s right edge in the Layout tab.

In this example we’ll use a Grid to hold the component we plan to embed. This choice

has been made simply to introduce the Grid container, which permits the placement of
