nil() vs isNil() - What's the difference?

[Chuck Tomasi]

What is the difference between the methods nil() and isNil()? I've seen both used in wiki and forum examples.

Example: Reference Field , http://community.service-now.com/node/1000544

This is where API docs would come in really handy.

And what is funny, in the wiki article: GlideElement - ServiceNow Wiki, they use isnil() in the example code.

Yes, I noticed that too

After reading all of this ... I felt good ... So to look @ ref field to see if htere is a active reference to a record in another table....

i would use ...

current.<some_ref_field>.isNil();

if there is no reference it would = true else false...

..... No joy.... I must be missing something.

I am trying to do this with a field style ...

Hi Jason,

Have you tried>

current.ref_field != ""

The nil() function is now documented here:

The isNil() function should not be used and does work in scoped applications.
