I see that the FlexibleOptionGroup overrides setParent of AbstractComponent throwing an UnsupportedOperationException (“The FlexibleOptionGroup component cannot be attached to an Application.”). Why is that?
I try to use FlexibleOptionGroup in a From, and Form.addField therefore miserably fails…
This because you should not add the FlexibleOptionGroup component itself to your application/layout. A quote from component’s overview from Vaadin Directory:
In your code you create a container but you don’t set it as a container data source for your FlexibleOptionGroup. I guess that when you call optionGroup.select(name); the component doesn’t contain an item with the itemId.
My answer is still the same. You call optionGroup.select(name) inside createTestContainer() which is called by optionGroup.setContainerDataSource(). At this point the the new container is not yet option group’s container so the option group doesn’t contain the item when optionGroup.select(name) is called.
Understood.
I corrected the code as You suggested but nothing changed.
@Override
public void postDraw() {
optionGroup = new OptionGroupNamed();
optionGroup.setContainerDataSource(createTestContainer());
optionGroup.setItemCaptionPropertyId(CAPTION_PROPERTY);
optionGroup.setItemIconPropertyId(ICON_PROPERTY);
optionGroup.setNode(this);
optionGroup.setMultiSelect(true);
optionGroup.addListener(this);
optionGroup.setImmediate(true);
mainComponent.setValue(calcolaSelected());
for (Iterator<FlexibleOptionGroupItemComponent> iter = optionGroup.getItemComponentIterator(); iter.hasNext();) {
FlexibleOptionGroupItemComponent comp = iter.next();
hl.addComponent(comp);
hl.addComponent(createCaptionLabel(comp));
}
int i = 0;
for(Iterator<Item> it = itemsGallery.keySet().iterator(); it.hasNext();) {
Item item = it.next();
Object name = item.getItemProperty(CAPTION_PROPERTY).getValue();
GalleryItem gi = itemsGallery.get(item);
i++;
if(i == 1 || gi.isSaved()) {
Object o = optionGroup.getItem(name);
optionGroup.select(name);
}
}
super.postDraw();
}
Now the select method is placed after the initialization, however nothing changed-
In order to verify if the id is correct, as you can see, I read it before I try to select and the correct object is retrived from the option group.
Why it doesn’t work, now ? the checkbox is still unchecked.
Tks

I’ve got a Vaadin application (6.7) that uses FlexibleOptionGroup (1.0.0) and the application works fine on my local machine development server (Windows - Tomcat 6) as well as on my main server (Linux - Tomcat 6).
I’ve recently been trying to migrate the Vaadin application to the OpenShift (JBoss) platform. It seems that the application is never returning from a
fop.setPropertyDataSource(property);
call, where fop is a FlexibleOptionGroup. I don’t get any exceptions thrown and I can’t figure out why it shouldn’t be returning (the property object I’m passing in appears to be normal). I have a System out just before and after the method call and the one before is displayed fine but the one after is not displayed.
Any ideas on why this method wouldn’t return or throw an exception on my OpenShift platform?
I’d be willing to share more information if you think it would be helpful in solving this mystery…
Thanks…

Its a very nice and useful add-on, thanks for that.
I have a requirement which leads to put some stylish RadioButton/CheckBox instead what browser provides. So I followed
http://jsbin.com/efewag/2/edit this website and used images. It uses the Label for the item I add.
Now I have to use this FlexibleOptionGroup component to show Radio/CheckBox in one of the columns in my Vaadin table. In the method of table.addTableColumnGenerator I am returning instance of ItemComponent from the option group.
new ColumnGenerator() {
@Override
public Component generateCell(Table source, Object itemId, Object columnId) {
return optionGrp.getItemComponent(itemId);
}
}
It returns one RadioButton/CheckBox, but without the Label element. I tried to add caption with each item by calling
optionGrp.setItemCaption(itemId, "Hi");
but its not happening. Is there a way so I can add a blank Label element to each Item it returns. Then only I will be able to manage it with my custom images.
I am getting the following error
constructor of FlexibleOptionGroupItemComponent is not visible when i try to do
FlexibleOptionGroupItemComponent
flexibleOptionGroupItemComponent=new FlexibleOptionGroupItemComponent(flexiOptionGroup, itemId);
Thanks for the reply Poovannan. However, I am still waiting for the answer to my 1st question. For time being, I managed to use Layout listener which holds FelxiOptionGroupComponent and associated Label. But this just seems like a workaround to me.
I am tryingg to use the addon, with 7.2.2 with MVP and CDI implementation, but i get this error
Widgetset ‘com.vaadin.DefaultWidgetSet’ does not contain implementation for org.vaadin.hene.flexibleoptiongroup.FlexibleOptionGroupItemComponent. Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.
