Re: How to refresh ListView on ModalWindow

2010-08-28 Thread Sven Meier 

Hi,

you're pushing your comments into the ListView.
Obviously changing the commentsList variable afterwards has no effect 
on what the ListView is iterating over.


To keep the comments up-to-date, use a model:

ListView eachComment=new ListView(eachComment, new PropertyModel(this, 
commentsList)){

Hi,

I have a list of products containing a link that should show a user comments
on each product in a modal window. I created a ModalWindow containing a
Panel. I send a list containing comments to this panel. I'm using a ListView
to show this comments e.g:

ListView eachComment=new ListView(eachComment, commentsList){

@Override
protected void populateItem(ListItem item) {
Comment comment=(Comment) item.getModelObject();
item.add(new 
Label(commentContent,comment.getContent()));
}
};

First time I select some product, the list is created in appropriate way.
However, when I close that ModalWindow and open another one for different
product, the first list is shown again. CommentsList containing the comments
is updated before populateItem is called, but it seems that I should make
something more. Do you have any suggestions?

I think you should prevent that SQLException from happening in the first
place by validating the form input.
Then use a FeedbackPanel to display suitable error messages. Just google for
example code with forms, it's basic stuff.

Otherwise, create a FeedbackPanel on your page, put a try .. catch block
around your sql methods and in case of an exception, write to the
FeedbackPanel using error(your message)

 Q2: (a little n00b question) how can I find out which component makes my
 page stateful?


Check the wicket-devutils and StatelessChecker. It allows you to use an
annotation to validate the component is really stateless.
