OH MY GOSH! I feel stupid now.

Thank you, Jens and Alberto :)

Hello,
Maybe you missed the @UiField annotations ?

I have a relatively simple composite widget that's using UIBinder in an MVC model.

DrawingSubmissionForm.ui.xml
****************************
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">

<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"

xmlns:g="urn:import:com.google.gwt.user.client.ui">

<g:HTMLPanel ui:field="pnlLineItems" addStyleNames="pnlLineItems">

<h1>Add Drawings</h1>

<g:FlexTable ui:field="tblItems" addStyleNames="tblItems"></g:FlexTable>

<g:Button ui:field="cmdCancel" addStyleNames="cmdCancel">Cancel</g:Button>

<g:Button ui:field="cmdSubmit" addStyleNames="cmdSubmit">Submit Drawings</g:Button>

</g:HTMLPanel>

</ui:UiBinder> 

DrawingSubmissionForm.java
****************************
public class DrawingSubmissionForm extends Composite {

public HTMLPanel pnlLineItems;

public FlexTable tblItems;

public Button cmdCancel;

public Button cmdSubmit;

interface Binder extends UiBinder<Widget, DrawingSubmissionForm> {}

private static final Binder binder = GWT.create(Binder.class);

interface DrawingSubmissionFormUiBinder extends

UiBinder<Widget, DrawingSubmissionForm> {

}

public DrawingSubmissionForm() {

initWidget(binder.createAndBindUi(this));

}

public HTMLPanel getPnlLineItems(){

return pnlLineItems;

}

public FlexTable getTblItems(){

return tblItems;

}

public Button getCmdCancel(){

return cmdCancel;

}

public Button getCmdSubmit(){

return cmdSubmit;

}

}

When I try to instantiate a new instance in my Presenter class, I get a new instance but all of the fields are null? 

public class DrawingSubmissionFormPresenter extends BasePresenter<DrawingSubmissionForm> implements ClosableViewInterface {

DrawingSubmissionForm view;

CloseListener closeListener;

OrderProxy quoteDTO = null;

public DrawingSubmissionFormPresenter(OrderProxy quoteDTO) {

super();

this.quoteDTO = quoteDTO;

initializeView();

initializeEventHandlers();

loadData();

}

@Override

public void addCloseListener(CloseListener arg0) {

this.closeListener = arg0;

}

@Override

protected void initializeEventHandlers() {

// TODO Auto-generated method stub

}

@Override

protected void initializeView() {

view = new DrawingSubmissionForm();

}

private void loadData(){

if(quoteDTO != null){

FlexTable table = view.getTblItems(); //view exists as expected but getTblItems() returns null???

table.removeAllRows();

int row = 0; //we start at 1 because row 0 is the header

for (OrderLineProxy lineDTO : quoteDTO.getOrderLines()) {

final DrawingFormSubmissionLine dl = new DrawingFormSubmissionLine();

dl.getDescription().setText(lineDTO.getOrderLine().getItemDescription1());

dl.line = lineDTO;

table.setWidget(row++, 0, dl);

}

}else{

Window.alert("Quote Line Items could not be loaded. Please close and try again.");

}

}

}

So, as my comment states, "view" exists as I expect but getTblItems() returns null? I do this exact same thing in multiple instance of this project but I can't seem to figure out what I did wrong here. Any help would be appreciated. :)
