Write to java object using netui:select tag

Question

Hello,
I am iterating through a hashmap of java objects using a netui-data:repeater.
<netui-data:repeater dataSource="{pageFlow.MyHashMap}">
<netui-data:repeaterItem>
<netui-data:repeater dataSource= "{container.item.HashMapOfEmbeddedObjects}">
<netui-data:repeaterItem>
<netui:select dataSource= "{container.item.type}" optionsDataSource= "{container.item.typeChoices}" /> </td>
<netui:select dataSource= "{container.item.default}"
optionsDataSource= "{container.item.defaultChoices}" /> </td>
</netui-data:repeaterItem>
</netui-data:repeater>
</netui-data:repeaterItem>
</netui-data:repeater>
The java object has a field "HashMapOfEmbeddedObjects" that is itself a hashmap of java objects. I want to be able to make a selection and have it be written to the
"type" and "default" fields of the embedded objects, but dataSource="{container.item.default}" does not save the value of the selection.
Is there anyway to use the netui:select tag to write to the field on a java object? Any help is greatly appreciated.

I have done it in the past. The java object need not be actionForm. The following write-up I found in edocs will help you achieve this.
Page Flow-Scoped Form Beans
Page Flow-scoped Form Bean instances have the same life-cycle as the Controller file instance. They are created and destroyed when the Controller file instance is created and destroyed. This makes Page Flow-scoped Form Beans useful for storing data that has been accumulated across many different JSP pages.
To create a Page Flow-scoped Form Bean instance, construct a public member variable of the Form Bean in the Controller file.
public class myController extends PageFlowController
public MyFormBean pageFlowScopedBean = new MyFormBean();
Once you have created a Page Flow-scoped instance of a Form Bean, you can pass the instance to action methods by using the @action form="form_bean" annotation.
public class myController extends PageFlowController
public MyFormBean pageFlowScopedBean = new MyFormBean();
* @jpf:action form="pageFlowScopedBean"
* @jpf:forward name="success" path="displayData.jsp"
protected Forward submit( MyFormBean form )
return new Forward( "success" );
Each time the submit() method is invoked, it is passed the same instance of the Form Bean, namely, pageFlowScopedBean, the instance that was created when the Controller file instance was created.

Good luck.
