There are two elements "systemid".
Should not be the element for system name "systemname"?
(As in the other xml structures.)
<collective2>
<hypotheticalEquity>
<system>
<systemid>123</systemid>
<systemid>Testovaci system</systemid>
<totalequityavail>100000.03</totalequityavail>
<cash>100000.03</cash>
<equity>0</equity>
<marginused>0</marginused>
</system>
</hypotheticalEquity>
</collective2>
Whoops! That’s obviously a big bug. I have now fixed it. Thanks for calling it to my attention.
