Hi all, It’s 3am in the morning and I still trying to do
something that seems simple… and yet impossible? Ok, I have a list of Person(s) that needs to be display in a
Form for update and create. For update, I was able to update the existing data just
fine. For create, my Form has a button, when click on it, it needs
to create an additional row with inputs for All of the Person attributes. I first tried to use _javascript_ to create the new row with
all the input fields empty. I used the Wicket’s path Patterns to generate these new input’s name( with new
index for this new entry). And on the serverside, I Do as follow: ·
Created a new ListView that has populateItem(…)
implemented. ·
Overrided newItem(…) and getListItemModel(…)
so that newItem(…) returns a new ListItem that associated To a new ListItemModel(I extended),
return by the getListItemModel(…) that I override. ·
The new ListItemModel I extended has
onAttach(…) overrided with logic that would add new and empty Person object to the existing List
of Person, that get from my ListView. getModelObject(…). Well this doesn’t work. The page did create additional
row of inputs for the new person. But when I submit the Form, Nothing get update to the existing list and the page come
back with just the previous data in the table and my new Person input is gone and no where to be found. My guess is, Wicket use the existing components in the page
to get posted data. And since my new entry inputs Created on the client never exist on the server. Therefore,
wicket does not know to go get it. If this is right, then how do I overcome this default
behavior? And if it is impossible to add new inputs on the client Browser then How do I do it on the server? Meaning, how do I
create the new inputs entries on the server so that wicket Can generate new inputs entry, and client can enter data and
submit it. Thanks for any helps, --danny "The essence of knowledge is, having it, to apply it;
