Passing empty string to externaltask script

System

If I have an externaltask script that takes one parameter and I pass in an empty string for that parameter (""), the other standard parameters, like Job ID, Task ID, etc. end up being empty as well. What the ****?

This is an example:

<command v='__TAG__('iw_home');/iw-perl/bin/iwperl __TAG__('iw_home');/httpd/iw-bin/test_script.ipl ""' />
