Can't add a Form component to an Item in RefreshingView!?

[Philip Watson <ph...@gmail.com>]

I'm new to Wicket. I'm a little impatient with this one... so here goes.

I have a RefreshingView, with each item getting a Fragment component
added to it in the populateItem() method. Each of these Fragment
components only contain Labels. All is well here.

However, whenever I add a single Fragment component that contains a
Form I get an exception: "java.lang.ClassCastException:
org.apache.wicket.markup.RawMarkup cannot be cast to
org.apache.wicket.markup.ComponentTag"

What I'm trying to do here is when an item is selected on a list, it
renders the selected item as a Form to be edited rather than being
displayed in labels. Only ONE line is selected at a time, so only need
the one form showing. Everything else is fine... Java/markup hierarchy
match, model usage is all good. I can get the Fragment component
containing the form to work outside a RefreshingView. So obviously it
has trouble rendering Forms inside a RefreshingView repeater. Can't
work it out.

Any help will be much appreciated.

Philip,
    Remember that some repeaters when are refreshed change their items. You
have to instruct no to create new items instances. Take a look at ListView.
I looked for Refreshing view but I couldn't see any class like that.

bye!
