According to TWiki/TWikiVariables#URLPARAM_name_get_value_of_a_URL

default="..."     Default value in case parameter is empty or missing

A user had this URL


and had this setting

%URLPARAM{"month" default="00"}% 

In TWiki 4.0.5 month was set to 00 because it came in "empty". Now, it returns simply an empty value.

One argument is that month is "set" to the null string, therefore the default value should not take effect.

The other argument is that the docs clearly state empty or missing and, as month is empty in the URL, the default should take effect.

Is this a bug or a confusion in the docs.

(Personally, I think "empty" should still mean "empty" and the URL above should cause month to pick up the desired default value.)
