Setting the valus of variable present in an Arraylist which is present in another arraylist

[Anky Gupta]

Hi

i am trying to build an application in which i have a array list inside another arraylist. i am using indexed properties also. i am able to fetch the values of the variables in arraylists but i am not able to save the values back to them.
here is my JSP code:

  <table border=1>
		<logic:iterate id="phase" name="createrequestform"
			property="request.phases" 
			indexId="i">

			<tr>
				<td><html:text property="estimates" name="phase" indexed="true"></html:text>
				</td>
				<td> </td>
			</tr>
			<logic:iterate indexId="index" id="deliverable" name="phase"
				property="deliverableList">

				<tr>
					<td><html:text name="deliverable" property="estimates" indexed="true"></html:text></td>
				</tr>
			</logic:iterate>
		</logic:iterate>
	</table>  

Here is my form bean:

  public class CreateRequestForm extends ActionForm {
	
	
	public CreateRequestForm() {
		// TODO Auto-generated constructor stub
		this.request = new Request();
	}
	private Request request = null;

	public Request getRequest() {
		return request;
	}

	public void setRequest(Request request) {
		this.request = request;
	}
	
	public PhaseDetails getPhase(int i){
		return request.getPhase(i);
	}
	
	
	public void setPhase(int i, PhaseDetails phase){
		request.setPhase(i, phase);
	}
		

}  



public class Request {
	public Request() {
		// TODO Auto-generated constructor stub
		
		PhaseDetails p = new PhaseDetails();
		p.setEstimates("phaseEstimates");
		phases.add(p);
	}
	
	private ArrayList<PhaseDetails> phases = new ArrayList<PhaseDetails>();

	public ArrayList<PhaseDetails> getPhases() {
		return phases;
	}

	public void setPhases(ArrayList<PhaseDetails> phases) {
		this.phases = phases;
	}
	
	public PhaseDetails getPhase(int i){
		return phases.get(i);
	}
	
	public void setPhase(int i, PhaseDetails phase){
		if (i < 0 || i >= phases.size()){
			phases.add(new PhaseDetails());
		}
		phases.set(i, phase);
	}
	
	
	
	
	
}




public class PhaseDetails {
	public PhaseDetails() {
		// TODO Auto-generated constructor stub
		Deliverable d = new Deliverable();
		d.setEstimates("deliverable estimates");
		deliverableList.add(d);
		
	}
	private String estimates = null;
	
	public String getEstimates() {
		return estimates;
	}

	public void setEstimates(String estimates) {
		this.estimates = estimates;
	}

	private ArrayList<Deliverable> deliverableList = new ArrayList<Deliverable>();

	public ArrayList<Deliverable> getDeliverableList() {
	
		return deliverableList;
	}

	public void setDeliverableList(ArrayList<Deliverable> deliverableList) {
		this.deliverableList = deliverableList;
	}
	
	
	public Deliverable getDeliverable(int index){
		System.out.println("in deliverable getter");
		Deliverable del = deliverableList.get(index);
		return del;
	}
	
	public void setDeliverable(int index, Deliverable deliverable){
		System.out.println("in phase setter");
		if (index < 0 || index >= deliverableList.size()){
			deliverableList.add(new Deliverable());
		}

		deliverableList.set(index, deliverable);
		
	}
	
}


public class Deliverable {
	private String estimates = null;

	public String getEstimates() {
		return estimates;
	}

	public void setEstimates(String estimates) {
		this.estimates = estimates;
	}
	
}

I am not able to set the value of estimates variable in Deliverable which is a item of deliverableList arraylist.

please respond
thanks in advance
