Parameters

Use the Parameters dialog to specify the content, behavior, and other configuration settings for the current component or task flow.

The fields available in the Parameters dialog depend on whether or not there is at least one producer component on the page, and the current component is a consumer component, for wiring parameters to events. When there are no producer components on the page, the dialog displays only parameter names and values. When there is at lease one producer component on the page, and the current component is a consumer component, a parameter can bind to either a specified value or to an event:

Values: Enter parameter values, or click the icon next to a field and select Expression Builder to open the Expression Editor to set the value using Expression Language (EL).
Events: Select from the available events in the Event list. More

When there is at lease one producer component on the page, and the current component is a consumer component, the Parameters dialog displays the following fields:

Element	Description
parameter name	The name of a parameter associated with the current component.
Value/Event	Select whether the parameter is set by a static Value or by an Event (if available).
Event	Select the event that is associated with the payload value that you want to pass to the parameter. The Event list shows all of the events that are defined for all producer components on the page.
from	If the consumer task flow or portlet "listens" for the event from only one producer component, select the associated producer component. Otherwise, leave with the default value of `Any Component` to allow the parameter to be set when any producer component on the page triggers the specified event.
payload	Select the input value for the associated parameter, passed dynamically when the event triggers.
