Chris,
We do the same thing in our action classes in order to avoid the page
refresh problem. However, we use the DynamicURI class directly, instead of
using the TemplateLink class. I did not take the time to see what the
differences are, but take a look at the following code and see if it helps.
It is similar to the redirect code in Turbine.java, but we use
addQueryData() for the parameters instead of addPathInfo() because we seem
to having trouble with that approach (a separate unrelated issue).
Kevin
...
// redirect to the same template, but without the action parameter
DynamicURI duri = new DynamicURI (data, true);
// pass on selected request parameters.
for (Enumeration e = data.getParameters().keys(); e.hasMoreElements(); )
{
String key = (String) e.nextElement();
// Pass on all parameters except the action.
if (!key.equalsIgnoreCase("action"))
{
String value = (String) data.getParameters().getString(key);
if (value != null && value.length() > 0)
{
duri.addQueryData((String)key, (String)value);
}
}
}
data.getResponse().sendRedirect(duri.toString());
