Has anyone else experienced issues when testing @future where if the method calling @future clears the input list then all of your test methods fail because the @future method thinks it has recieved a null list? See the code below. Thoughts: bug or feature?

 

There is a work around: do not use .clear() but instead re-create the list (i.e. move the list  

subsetAccountIds inside of the While loop below).

 

So next question - what is better for memory? clear an array or "re-create" the array? I would think clear() is more explicit and would free up the memory "immediately" whereas overwriting the array would be subject to gargage collection to dump the memory.

 

Thanks,
