warning if some object are empty in NetworkConfigSection

Hello,

When I execute a modification of the networkconfigsection of a deployed vapp, I have some warning messages if some objects are empty. But these object have to be empty for our purpose.

for example :

if I want to have a Natservice enabled but without NatRule,so I want to have something like this :

<NatService>
   <IsEnabled>true</IsEnabled>
   <NatType>portForwarding</NatType>
   <Policy>allowTraffic</Policy>
</NatService>

I've got this warning message :

PHP Warning:  Invalid argument supplied for foreach() in /home/yconan/e2cdelta/trunk/lib/library/VMware/VCloud-1.0.0-314767/API.php on line 4982

it seams that there is no test on $this->NatRule to know if it's set. For the moment I resolve this by adding something like this around line 4982:

if (isset ($this->NatRule))
        {
          foreach ($this->NatRule as $NatRule) {
              $tagName = $NatRule->get_tagName();
              if (empty($tagName)) {
                  $tagName = 'NatRule';
              }
              $out = $NatRule->export($out, $level, $tagName, '', $namespace, $rootNS);
          }
        }

But I'am not sure that is a good solution. Is there another method to create a Natservice without rules and without having these warning messages ?

I have the same problem :

when it is needed to have a NetworkConfig  section empty on line 22713 in API.php

when it is needed to have a NetworkConnection section empty on line 23525 in API.php
