Hi,
Thanks for Lachlan's response. But I'm a little bit confused.
Does that mean I have to add a button, says, "Refresh the sales," to invoke the refresh action? Or can I just use the refresh button on my browser to do that?
Thanks for the help.
Regards,
yllan

/** Add a refresh action to your page to update the list */
public WOComponent refresh()
{
saleRecords = null;
return this;
}
}
