What is the type of items in the ComboBoxes (what container type?). What is the Property value type of for example the property “Portal Institution”?

hai Johannes ,

I am using a BeanItemContainer and here portalInstituion is an entity.

this is my entity…

@Entity
public class PortalUser implements java.io.Serializable {

private static final long serialVersionUID = 1L;
private Long id;
private PortalInstitution portalInstitution;

    ..................................

}

this is my controller class

BeanItemContainer portalUser=new BeanItemContainer(PortalUser.class);

		portalUser.addAll(usersList);
	
		userTable=new Table(null,portalUser);

When I press the edit button the following code will be executed…

panel.getApplication().getMainWindow().addWindow(
new PortalUserEditor((BeanItem) userTable.getItem(userTable.getValue()));

this is in my editor class

public Field createField(Item item, Object propertyId, Component uiContext) {

	String pid=(String)propertyId;
	try{
	if(pid.equals("portalInstitution")){
		System.out.println("....in inst.....");
		List<PortalInstitution> institutions=(List<PortalInstitution>) portalInstGenHome.getActiveInstitution();
		
		institutionsSelect.setWidth("200px");
		institutionsSelect.removeAllItems();
		
		if (institutions != null && institutions.size() > 0) {

			for (PortalInstitution institution : institutions) {
				
				institutionsSelect.addItem(institution);
				institutionsSelect.setItemCaption(institution, institution.getInstName());
			}
		}
		return institutionSelect;
}

please give a solution…thanks…

Did you resolve this already? I guess none of the instances of PortalInstitution from portalInstGenHome.getActiveInstitution() equal to PortalUser.portalInstitution. When setting the current selection of Select the container.containsId is called and that eventually calls List.contains which compares id objects with equals.
