Examples

The following example shows multiple actions for the customer WDO:

app.apph.actions( ["customer.zip.disable"          // Disable customer.zip ,"customer.name.enable"        // Enable customer.name ,"customer.country.focus"      //Set focus to customer.country ]);

The following example shows how to get the customer state field screen value. If there is no screen value, then the underlying data value is retrieved:

apph.action('customerfullo.state.get');

The following example shows how to execute the dynamic lookup for a field:

apph.action('customerfullo.state.lookup');

The following example shows how to set the customer state field screen value. Note that the value is separated by the pipe (|) symbol:

apph.action('customerfullo.state.set|NH');

The following example shows how to display the customer state field, presumably after it was previously hidden by wdo.field.hide:

apph.action('customerfullo.state.show');
