Hi, when we test somethis like this:
<if test="param != null and param != ''">
only works if param type is String, otherwise it fails in some cases

For excample:

if param is number and the value is 0.0 then test returns FALSE but param have a value.

if param is boolean and the value is false then test returns FALSE but param have a value.

There is a bug? Can we solve it is someway or we hace to chage all de if test? (we have more than 1500 ocurrences)
