I'm trying to test if a value is a number.
I thought I could do this:
var test='not_a_number';
var test2='4.00';
num_test=parseFloat(test);
if(num_test == 'NaN'){alert('that was not a number')}

have. When I apply the extension attribute to the the calling function in the
proxy class I get an error 'Value cannot be null'. When the extension
attribute is not applied it runs fine. The wierd thing is that it does not
appear to be an error within the SOAP extension because I break-pointed it
and when the proxy function gets called the SOAP extension runs fine....

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
