UI-Controls with a valid BindingProperty that get created in the DetailsSection of a MasterDetailsComposite, won't be bound automatically like expected but rather have to be registered manually by calling addUIControl.
For Example this Code does not make the Ridgets available in the SubModuleController:

MasterDetailsComposite mdComposite = new MasterDetailsComposite(result, SWT.NONE, SWT.BOTTOM);
Composite details = mdComposite.getDetails();
details.setLayout(new GridLayout(2, false));

UIControlsFactory.createLabel(details, "First Name:"); 
Text txtFirst = UIControlsFactory.createText(details, SWT.BORDER, "first"); 
txtFirst.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));

UIControlsFactory.createLabel(details, "Last Name:"); 
Text txtLast = UIControlsFactory.createText(details, SWT.BORDER, "last"); 
txtLast.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false, 1, 1));

this.addUIControl(mdComposite, "master"); 

The UIControlsFactory creates a TextField and sets the bindingProperty on the Control, but if you call getRidget("first") in the associated SubModuleController it will result in a NullPointerException, because the Ridget is not available.
