or even better, it should really be something like this
class deleteuserlink extends link {
protected void oncomponenttag(tag) {
string uname=((user)getmodelobject()).getusername();
tag.put("onclick", "return alert('are you sure you want to
delete "+uname.....
}
}
and in your code you should be doing
add(new deleteuserlink("delete-user", usermodel));
this is where wicket really shines, it lets you work with objects and
models. especially in the next release where you can do
class deleteuserlink extends link<user> {
protected void oncomponenttag(tag) {
string uname=getmodelobject().getusername();
tag.put("onclick", "return alert('are you sure you want to
delete "+uname.....
}
}
