Page Properties: Parameters

Page parameters allow communication between components and the pages that contain them by providing a means of storing values for passing to page components that have been configured to consume them.

Note:

If you change a page parameter value, the new value is immediately saved. You cannot revert back to the prior value. Therefore, take note of parameter values before you change them in case you want to set them back to their original values.

To add or modify page parameters:

1. On the Parameters tab, modify existing parameters as required.

   Note:

   All parameter values provide access to an Expression Language (EL) editor, which you can use to select or specify a variable value instead of a constant value. Click the Edit icon next to a value field, then select Expression Builder to open the editor. If you need EL assistance, an application developer can provide an EL expression.

   System pages include a default page parameter: .

   • pg_pageTemplateID: By default, specifies the system page using the default page template for the system page. To use a custom page template for the system page, enter a GUID value for the new page template.

2. To add a new parameter:

   • Click Add a page parameter.

   • In the Add a Page Parameter dialog, enter a new parameter Name, then click Add Parameter to add the parameter to the Parameters tab, with a value entry field.

   • Optionally, enter a value for the new parameter.
