This page is for application designers who need to configure functionality for components or events. It explains the properties for the view node, which is part of an actionflow.
Overview
When you are designing screens, you use a view to select and filter data for display. In an actionflow, the originating screen or component may not include all of the data that the actionflow requires. In this case, use a

|
node to select and filter additional data to use in the actionflow.
How the actionflow processes the view data depends on whether the view is wired via a driving or lookup connection.
- For a driving connection, records are returned individually to the view node and flow one by one through the remainder of the actionflow.
- For a lookup connection, the records are returned as an array within one recordset. Lookup views require both:
- Data Attributes: the attributes being passed into the view node.
- Request Attributes: the attributes from which you need to lookup data.
When you create a view node, PhixFlow prompts you to select the table on which this view is based. PhixFlow opens the Attributes window and the view node properties.
Drag attributes from the Attributes window and onto the Data Attributes or Request Attributes sections. You can add attributes from the base table and from related tables..

- Requested - a lookup view

Default Sort Order | Select a sort order, or click to create a new one; see Sort Order. The sort order determines the order the data is retrieved. |
Default Filter | Select a filter, or click to create a new one; see Sort Order. A filter determines what data is retrieved. To reference attributes present in the Filter Attributes, use _filter.[AttributeName] . |

- To add a new input connection point, in the section toolbar click to open a new input connection point and set its properties; see Input Connection Points.
- To edit an existing input connection point, double-click it in the list to open its properties.
- To remove an input connection point, select one and in the section toolbar click

Order | The order of the attribute. Attribute expressions are evaluated in this order. This is important when you need to use the results of a calculation in another attribute: - either in its expression
- or in a $ variable.
In the attribute list, the attribute that calculates the result must come before the attribute that requires the result. |
Request Attributes
