Hi,
Thanks for the reply, but it does not work, still same error, i check the
LinkImpl:
public void addParameter(String parameterName, String value)
{
Defense.notBlank(parameterName, "parameterName");
Defense.notBlank(value, "value");
if (parameters == null)
parameters = CollectionFactory.newMap();
parameters.put(parameterName, value);
}
it is making sure the value is not blank, but I believe query string having
blank value is often.
