Mapping the response to the List component

Of particular importance in this document is the list of products. We will define a rule to transform this document from the response format to a CDF format suitable for the jsx3.gui.List. CDF stands for Common Data Format. CDF is a GI convention for normalized client-side data so that multiple GUI components can provide views into single sets of data (e.g. the same data can be viewed as a List, a Chart, and a Menu, etc... all at the same time just by binding those GUI components to the CDF object). The List infers a flat, non-hierarchical set of nodes. We do that by selecting one of the Product Nodes and defining a CDF rule. Let's create one in the XML Mapping Utility rule editor.

For the list node we specify that the rule should create a new CDF document and place it in GI's data cache with a name of "priceList". This key is important as we have specified the list gui component with the same key.

Next we define the rows in the document.





Finally we define the attributes on the record. Note the attribute names are the same as the path property in the list column.
