Common workflow for the RDBMSResolver component
The following steps describe the typical workflow for the RDBMSResolver component.
To use an RDBMSResolver component:
Add two instances of the WebServiceConnector component and one instance of the DataSet
1.
and RDBMSResolver components to your application, and give them instance names.
Select the first WebServiceConnector component. Then use the Parameters tab of the
2.
Component inspector to enter the Web Service Definition Language (WSDL) URL for a web
service that exposes data from an external data source.
Note: The web service must return an array of records to be bound to the data set.
Use the Bindings tab of the Component inspector to bind the first WebServiceConnector

data elements (DataSet fields) to the visual components in your application.
Bind the DataSet's deltaPacket property to the RDBMSResolver's deltaPacket property.

The update instructions are sent from the DataSet component to the RDBMSResolver
component when the

params property to send data back to a method that will parse the XML update packet. Set the
kind of that params property to auto-trigger so that the connector will send the update packet
as soon as data binding copies it over.
Add a trigger to initiate the data binding operation: use the Trigger Data Source behavior

attached to a button, or add ActionScript.
In addition to these steps, you can also use the RDBMSResolver component to create bindings to
apply the result packet sent back from the server to the data set.
