Java Generation Code Generation Issues When Creating Outside Eclipse

Question

I configured the Maven build for the very small GWT project that I have. Compiling / starting from Eclipse does not cause problems, but when I build Maven, I have problems compiling in one place (this is the code on the client side of GWT, but I'm not sure if it is). Maven output / compilation:

[..]SmartTable.java:[63,52] ')' expected
[..]SmartTable.java:[63,53] ')' expected
[..]SmartTable.java:[63,69] ';' expected
[..]SmartTable.java:[63,71] not a statement
[..]SmartTable.java:[63,77] ';' expected
[..]SmartTable.java:[63,79] not a statement

.. where this particular line is defined as follows:

final Comparator<T> comparator = ((SmartTable<T>.ComparableColumn) column).comparator;

As you may have guessed, I repeat all the columns defined for this generics class (which I call "SmartTable") and get a comparator (of course, if the column instance is SmartTable.ComparableColumn) for further operations. The Column and ComparableColumn classes are nested in SmartTable, and their headers look like this:

public abstract class Column {
    // private String id;
    private String caption;
    private int width;
    private Filter<T> filter;
...
public class ComparableColumn extends Column {
    private Comparator<T> comparator;
...

EDIT:

public class SmartTable<T> extends FlexTable {
    private List<Column> columns = new ArrayList<Column>();
    ...
    private Comparator<T> currentComparator;
...

    public void init(Comparator<T> defaultComparator) {
        this.currentComparator = defaultComparator;
        ...
        int index = 0;
        for (Column column : columns) {
            ...
            if (column instanceof SmartTable.ComparableColumn) {
                @SuppressWarnings("unchecked")
                final Comparator<T> comparator = ((SmartTable<T>.ComparableColumn) column).comparator;
            ...
    }
...

    public abstract class Column {
        // private String id;
        private String caption;
        private int width;
        private Filter<T> filter;
        private List<WidgetCreator<T>> widgetCreators;

        public Column(/* String id, */String caption, int width, Filter<T> filter, List<WidgetCreator<T>> widgetCreators) {

...

    public class SimpleColumn extends Column {
        public SimpleColumn(/* String id, */String caption, int width, Filter<T> filter, List<WidgetCreator<T>> widgetCreators) {
            super(/* id, */caption, width, filter, widgetCreators);
        }

...

    public class ComparableColumn extends Column {
        private Comparator<T> comparator;

        public ComparableColumn(/* String id, */String caption, int width, Filter<T> filter,
                List<WidgetCreator<T>> widgetCreators, Comparator<T> comparator) {
            super(/* id, */caption, width, filter, widgetCreators);
            this.comparator = comparator;
        }

...

}

EDIT2: :)

public class SmartTable2<T> {
    public void init() {
        Column c = new ComparableColumn();

        final Comparator<T> comparator = ((SmartTable2<T>.ComparableColumn) c).comparator;
    }

    class Column {

    }

    class ComparableColumn extends Column {
        Comparator<T> comparator;
    }
}

Answer 1

:

Comparator<T> comparator = (Comparator<T>) ((SmartTable.ComparableColumn) column).comparator;

EDIT: :

Comparator<T> comparator = ((SmartTable.ComparableColumn) column).comparator;

?

public class Main {

    public static <T> void main(String[] args) throws Exception {
        SmartTable<T>.Column column = new SmartTable<T>().new Column();
        Comparator<T> comparator = ((SmartTable.ComparableColumn) column).comparator;

    }

    static class SmartTable<T> {
        class Column {

        }
        class ComparableColumn extends Column {
            Comparator<T> comparator;
        }
    }

}

javac ( , ), (SmartTable.ComparableColumn), .
