Re: [Xen-API] perl Xen API How to

Mike,
        I tried encoding value as Boolean using XMLRPC::PurePerl it didn't work.
For second part I tried passing int($min) instead of $min but still didn't work.

Regards,
Rawat

This looks like a Perl XMLRPC problem to me. See here:

http://search.cpan.org/~rdietrich/xmlrpc-pureperl-0.03/lib/XMLRPC/PurePerl.pm#DATATYPES:

You can use that to explicitly encode a value as a boolean. I'm not much of a 
Perl expert, so I don't know if that library is compatible with yours, but I 
guess that link should get you moving in the right direction.

For your question below, those values are supposed to be integers. I'm not sure 
why you'd be getting a field error there; maybe Perl is treating 'min' as a 
string? (Everything in Perl is a string, right? ;) )

You probably know this already, but make sure you have the XenAPI reference at 
hand when working with the API:
