Re: Runtime error

Walfredo,

Facilty, which then calls the first object of a collection. From these lines of 
the
bt you can see that the collection is empty, thus doesn't have a first  member 
and
this causes a runtime error:

_i_Collection_any__atOffset_(0x2429d8,0x1c6cec,0x0,0x401a0,0x0,0xef595624)
+ 58
_i_Collection_any__getFirst(0x2429d8,0x1bfe5c,0x40518,0x81b3c,0xc,0x242f70)
+ 24
_i_Facility__update(0x23b258,0x1c0128,0x0,0x0,0x28,0x242f70) + 54

You have to put some code into Facility that prompts the collection for number 
of
members [collection count] and doesn't do the getFirst call if it count is 0.
