two requests from one table sort or update

Hello, I can't reproduce the bug in a simple example, so I have to show what I got, and hope someone can guess what it is that sends two responses back.
This is an older issue: SEE HERE

Vaadin version: 6.7.3
Tomcat version: 7.0.16
*in attempts to reproduce this it doesn't happen, using the same environment, so it's something else
*this also happens if only one table is on the screen, so that's not it either

'm using a compiled widgetset because I removed some of them, could this be it?

<generate-with class="view.MyWidgetMapGenerator">
		<when-type-is class="com.vaadin.terminal.gwt.client.WidgetMap" />
	</generate-with>

the different part being "sortcolumns0PID84" in these two reponses

Relevant code:

package view.ui.tables.nrs;

import model.POJOs.Archive;
import model.managers.ArchiveManager;
import model.managers.Cache;
import view.MyBeanItemContainer;

import com.vaadin.data.Container;
import com.vaadin.ui.Table;

public class ArchiveTable extends Table {
	public final static Object[] NATURAL_COL_ORDER = new Object[] { "id",
			"date", "nr1", "nr2", "nr3", "nr4", "nr5", "nr6" };

	public static String[] COLUMN_NAMES = { "Id", "Date", "Nr1", "Nr2", "Nr3",
			"Nr4", "Nr5", "Nr6" };

	public ArchiveTable() {
		this(new MyBeanItemContainer(Archive.class, ArchiveManager.listArchive(
				Cache.MIN_RANGE, Cache.MAX_RANGE)));
	}

	public ArchiveTable(int minLimit, int maxLimit) {
		this(new MyBeanItemContainer(Archive.class, ArchiveManager.listArchive(
				minLimit, maxLimit)));
	}

	public ArchiveTable(Container dataSource) {
		setContainerDataSource(dataSource);
		setPageLength(10);
		setCacheRate(1);
		setColumnCollapsingAllowed(true);
		setColumnReorderingAllowed(true);
		setVisibleColumns(NATURAL_COL_ORDER);
		setColumnHeaders(COLUMN_NAMES);
	}

}

The flow is pretty much this:

drawContent(new ArchiveTable(), new ArchiveTable(minLimit,
				maxLimit));

if tables aren't null for some reason, add them on layouts, then add the layouts on main layout

protected void drawContent(Table globalTable, Table localTable) {
		drawContent(globalTable, localTable, new HorizontalLayout());
	}

	// TODO: check for existence of previous controls in main, then check if
	// they are the same with the ones about to be added, if not, add them
	protected void drawContent(Table globalTable, Table localTable,
			AbstractOrderedLayout mainLayout) {
		this.mainLayout = mainLayout;
		this.mainLayout.setSizeUndefined();
		this.mainLayout.setMargin(true);

		if (globalTable != null) {
			globalLayout = new HorizontalLayout();
			globalLayout.setSizeUndefined();

			if (this.globalTable == null)
				this.globalTable = globalTable;
			globalLayout.addComponent(this.globalTable);
			globalParamsLayout = globalParams();
			globalSideControls = globalSideControls(globalParamsLayout);
			globalLayout.addComponent(globalSideControls);
			mainLayout.addComponent(globalLayout);
		}
		if (localTable != null) {
			localLayout = new HorizontalLayout();
			localLayout.setSizeUndefined();
			if (mainLayout instanceof HorizontalLayout)
				localLayout.setMargin(false, false, false, true);
			else
				localLayout.setMargin(true, false, false, false);

			if (this.localTable == null)
				this.localTable = localTable;
			localLayout.addComponent(this.localTable);
			localLayout.addComponent(localSideControls(localParams()));
			mainLayout.addComponent(localLayout);
		}
	}
