In Sitecore you cannot compare an ID with NULL; it will produce the following error:
The call is ambiguous between the following methods or properties: ‘Sitecore.Data.ID.operator ==(Sitecore.Data.ID, Sitecore.Data.ID)’ and ‘Sitecore.Data.ID.operator ==(Sitecore.Data.ID, Sitecore.Data.ShortID)’
I.e. the following code is invalid:
Sitecore.Data.ID someID = GetSomeID();
if (someID == null)
{
// do code
}
Instead, you need to call Sitecore.Data.ID.IsNullOrEmpty():
ID someID = GetSomeID();
if (Sitecore.Data.ID.IsNullOrEmpty(someID))
{
// do code
}
A quick tip for you.

You can remove the ambiguity if you wish like so as well:
if(myId == (ID)null) { … }
Though I suppose ID.IsNullOrEmpty() also checks for ID.Null.
