Expansion statements are calculated when:

• the page is recalculated

• the form is saved

The following example shows a field definition that uses conditional logic to convert the value derived for the location field in the previous example back into a three-letter abbreviation that will be stored on the Oracle resource. Notice the difference in the field names. The location field value is not saved on any resource. It is used to calculate another field.

<Field name=’accounts[Oracle].locCode’>
   <Expansion>
      <switch>
         <ref>location</ref>
         <case>
            <s>Austin</s>
            <s>AUS</s>
         </case>
         <case>
            <s>Houston</s>
            <s>HOU</s>
         </case>
         <case>
            <s>Dallas</s>
            <s>DAL</s>
         </case>
      </switch>
   </Expansion>
</Field>
