you dont need to do anything. next request the dataprovider is polled again.
if the dataview really doesnt refresh make sure your dataprovider/orm layer
are not doing any caching.

Hi again,
I have a simple DataView where one of the columns contains a Link which
onClick modifies the data. What is the best way of telling the DataView
that the model has changed. I've tried a few things, see the comments
in the code....
Thanks for your help,
Tim
DataView dataView = new DataView("tasks",
new UserTaskDataProvider(user)) {
protected void populateItem(final Item item) {
final TaskInstance task = (TaskInstance)
item.getModelObject();
item.add(new Label("taskName",
task.getName()));
// add a link that, when clicked,
assigns the task back to
// the group
Link assignLink = new Link("assignLink")
{
@Override
public void onClick() {
ATMInstallsDao.getFromApplicationContext()
.assignTaskToGroup(task.getId(),
"InstallsTeam");
//-------------PLEASE
HELP WITH THIS BIT---------
// tell wicket that
we've changed the model so it
// updates the page
//tried.......
// modelChanged(); -
does nothing (the Link objects model??)
//
DataView.this.modelChanged(); - does not compile no DataView parent???
// This works but is not
really the most efficient!.....
getRequestCycle().setResponsePage(new UserTasksPage(userName));
//------------------------------------------------
}
};
assignLink.add(new
Label("assignLinkLabel",
"assign to group"));
item.add(assignLink);
}
};
