The Log Exception scriptable task element performs the following scripted function.
//Writes the following event in the vCO database
Server.error("Coudln't snapshot the VM '"+vm.name+"', exception: "+errorCode);
Set Output Scriptable Task Element
The Set Output scriptable generates the workflow's output parameter, that contains the array of virtual
machines of which snapshots have been taken. The following table shows the bindings that the Set Output
scriptable task element requires.
