Create links

Hello,
i have a question about links , i want to link two objects in the same Module , i use the following syntax:

Object source -> Object target

.....
int abs = o."Absolute Number"
Object oStart = object abs
int iReference = intOf realOf Reference
Object oEnd = object iReference
oStart -> oEnd 
.....

i get error in <line 6> null Object parameter was passed into argument position 2

I know I'm missing something simple. Can someone out there please clue me in? Thanks!

Obviously, oEnd is null.

The reason is probably that either Reference is an empty string or iReference is a number that references an object that is not available in the current view.

print is your friend...

.....
int abs = o."Absolute Number"
    print "abs is ->" abs "<-\n"
Object oStart = object abs
    print "oStart is " (null oStart? "null" : oStart."Absolute Number""") "\n"
    print "Reference is ->" Reference "<-\n"
int iReference = intOf realOf Reference
    print "iReference is -> " iReference "<-\n"
Object oEnd = object iReference
    print "oEnd is " (null oEnd? "null" : oEnd."Absolute Number""") "\n"
oStart -> oEnd

By the way: variable "o" already contains the start Object. There is no reason to extract the absolute number from o and then get the object corresponding to the absolute number again. So, just use "o -> oEnd" or if you want to, create a variable "Object oStart = o"

int abs = o."Absolute Number"
    print "abs is ->" abs "<-\n"
Object oStart = object abs
    print "oStart is " (null oStart? "null" : oStart."Absolute Number""") "\n"
    print "Reference is ->" Reference "<-\n"
int iReference = intOf realOf Reference
    print "iReference is -> " iReference "<-\n"
Object oEnd = object iReference
    print "oEnd is " (null oEnd? "null" : oEnd."Absolute Number""") "\n"
oStart -> oEnd

Hello Miki,

thank u for your reply , i do it and i get error in <line 11> Cannot create link: no access to source object 

and oStart is available

hm, are you sure that you have write access to oStart? Did you open the module in Exclusive Edit mode?
