Support For Immutable Objects

I've noticed that PropertyUtils only looks for properties that contain only a set Method. However, are there any plans in the future to support an immutable object? (Read-only)

NPE and other Exception building an int property

Starting from Swing sample PersonApp, if you just add a simple int property to class PersonApp:

[PersonApp.java]
private int number;
public void setNumber(int number) {
    this.number = number;
}
public int getNumber() {
    return number;
}

[PersonApp.yml]
JFrame(name=frame, title=frame.title, size=packed, defaultCloseOperation=exitOnClose):
    - JButton(name=save, text=button.save, onAction=[$validate,save,done])
    - JButton(name=cancel, text=button.cancel, onAction=[$confirm,cancel])
    - MigLayout: |
          [pref]              [grow,100]     [pref]             [grow,100]
          "label.firstName"   txtFirstName   "label.lastName"   txtLastName
          "label.email"       txtEmail+*
          >save+*=1,cancel=1
    - number: 1
bind:
    - txtFirstName.text: person.firstName
    - txtLastName.text: person.lastName
    - txtEmail.text: person.emailAddress
validate:
    - txtFirstName.text: {mandatory: true, label: label.firstName}
    - txtLastName.text: {mandatory: true, label: label.lastName}
    - txtEmail.text: {mandatory: true, emailAddress: true, label: label.email}

results in a NPE

changing Buider.java, lines 850 to (bold text) could resolve problem..:

                        String sValue = parent.getStringProperty(currentKey);
                        if (sValue != null && sValue.matches(asValueHandler.getRegex())) {
                            //replace the value from the file with the corresponding object instance
                            parent.getProperties().put(currentKey, asValueHandler.getValue(process, parent, currentKey, 
                                    parent.getProperty(currentKey)));
                        } else {
                            throw new BuildException("Invalid {0} value \"{1}\" for {2}.{3}. Must in be in \"{4}\" format, e.g. \"{5}\"",
                                    propertyType.getSimpleName(), sValue, parent.getMainObject().getClass().getSimpleName(),
                                    currentKey, asValueHandler.getRegex(), asValueHandler.getInputValueSample());
                        }

unfortunately, this does not solve the issue.. the subsequent exception is throws:

Invalid int value "null" for PersonApp.number. Must in be in "\d+|[a-zA-Z0-9_]+" format, e.g. "3 | SOME_CONSTANT_VALUE | someConstantValue"

My question at this point is, is it possible to use properties other than String in yml files, and assign them to java class?

Support for absolute layout and java.awt.Point

I see that support for absolute layout is missing in the project.
In my case I would find it very useful in order to provide customers with a simple embedded swing editor in my application, oriented to only particular components (like SCADAs).

I think it would be enough to support a syntax for the Component#setLocation(Point p) or Component#setLocation(int x, int y) methods. All other stuffs are already working.. (more generally speaking, as you already support a special syntax for Dimension (like 800x600), a similar syntax should be fine for Point as well..).
In addition, Container#setLayout(null) must be called somewhere.. something like this:

JFrame(name=frame, title=frame.title, size=800x600, defaultCloseOperation=exitOnClose):
    - AbsoluteLayout()
    - JButton(name=button, text=button.acton, location=100;50)

(I don't know which char to use to separate x from y in location... ; should fit be maybe..)

what do you think about that?

Stream API Support

Add stream API support so that we don't have to write custom methods for doing simple stuff.
