Currently I'm facing quite weird problem with Vaadin Table. If I use AbsoluteLayout data in table are not shown, but if I use i.e. HorizontalLayout, data are perfectly shown.
This works:
import com.vaadin.annotations.AutoGenerated;
import com.vaadin.ui.CustomComponent;
import com.vaadin.ui.HorizontalLayout;
import com.vaadin.ui.Table;
public class MyComposite extends CustomComponent {
@AutoGenerated
private HorizontalLayout mainLayout;
@AutoGenerated
private Table table;
public MyComposite() {
buildMainLayout();
setCompositionRoot(mainLayout);
// TODO add user code here
table.addContainerProperty("First Name", String.class, null);
table.addContainerProperty("Last Name", String.class, null);
table.addContainerProperty("Year", Integer.class, null);
table.addItem(new Object[] { "Nicolaus", "Copernicus",
new Integer(1473) }, new Integer(1));
table.addItem(new Object[] { "Tycho", "Brahe", new Integer(1546) },
new Integer(2));
}
@AutoGenerated
private HorizontalLayout buildMainLayout() {
// common part: create layout
mainLayout = new HorizontalLayout();
mainLayout.setStyleName("blue");
mainLayout.setImmediate(false);
mainLayout.setWidth("100%");
mainLayout.setHeight("100%");
mainLayout.setMargin(false);
// top-level component properties
setWidth("100.0%");
setHeight("100.0%");
// table
table = new Table();
table.setImmediate(false);
table.setWidth("100.0%");
table.setHeight("100.0%");
mainLayout.addComponent(table);
return mainLayout;
}
}
But this doesn't:
import com.vaadin.annotations.AutoGenerated;
import com.vaadin.ui.AbsoluteLayout;
import com.vaadin.ui.CustomComponent;
import com.vaadin.ui.Table;
public class MyComposite extends CustomComponent {
@AutoGenerated
private AbsoluteLayout mainLayout;
@AutoGenerated
private Table table;
public MyComposite() {
buildMainLayout();
setCompositionRoot(mainLayout);
// TODO add user code here
table.addContainerProperty("First Name", String.class, null);
table.addContainerProperty("Last Name", String.class, null);
table.addContainerProperty("Year", Integer.class, null);
table.addItem(new Object[] { "Nicolaus", "Copernicus",
new Integer(1473) }, new Integer(1));
table.addItem(new Object[] { "Tycho", "Brahe", new Integer(1546) },
new Integer(2));
}
@AutoGenerated
private AbsoluteLayout buildMainLayout() {
// common part: create layout
mainLayout = new AbsoluteLayout();
mainLayout.setStyleName("blue");
mainLayout.setImmediate(false);
mainLayout.setWidth("100%");
mainLayout.setHeight("100%");
// top-level component properties
setWidth("100.0%");
setHeight("100.0%");
// table
table = new Table();
table.setImmediate(false);
table.setWidth("100.0%");
table.setHeight("100.0%");
mainLayout.addComponent(table);
return mainLayout;
}
}
Names of columns are shown in both cases. Can someone tell me why this happens? Thanks in advance.
