Connections between portlets


The Portlet Wiring Tool enables connections, or wires, between cooperative portlets, allowing the exchange of property information using the property broker.

Options include...

If a property is available in common available between two portlets, we can create a wire between the two portlets.

We can exchange properties across pages using cross-page wires. The target page must have receiving actions defined as global on its portlets, which makes that action available to Click-to-Action menus. To set an action as global, navigate to the target page, and from the drop-down menu on the title bar, select...

This will bring up a listing of the portlets on a page and their corresponding receiving actions.

As an alternative to the Portlet Wiring Tool, wires can also be created interactively in the portlet. Depending on the browser, users with sufficient permissions can create wires by holding either the CTRL or ALT keys and clicking an icon or hotspot in the portlet that is already associated with a Click-to-Action function. A dialog is displayed that allows the user to create a wire to other portlets on the page.

The wiring tool allows wires to be created in situations which are not handled by the interactive approach.

For example, the tool does not require the existence of Click-to-Action menus to initiate wire creation It can be used to create multiple wires from a single source property (using the interactive approach, a single source can be wired to a single target or all targets, not an arbitrary subset). Wire creation or deletion is subject to the access control checks as described later.

To view the tool itself, users must possess at least "User" role permissions on the page and the portlet. Further access checks are performed before allowing the user to view, create, or delete wires between portlets. The user must possess at least "User" role permissions on a page and the wired portlets on it to be able to view wires for the page. Users may also be able to create or delete personal wires, which affect their view of the page, or create or delete public wires, which affect all users' view of the page. Users must possess at least "Privileged User" role permissions on the page and "User" permissions on the portlets to be able to create or delete personal wires, while at least "Editor" role permissions are required on the page and "User" permissions on the portlets to be able to create or delete public wires.
