Empty portal

[zab]

Hello

I have a portal that can be access from a menu on top of it, wich display different categories (to sort the items). In each categories I can add items into the portal using a script. I do not want to allow the creation of records from the portal. I prefer a script because it goes to the related LineItem to get some variable and sets some fields first. Everything goes very well except when the portal is empty. Then I can't get last field information (of course) and I can't find the right way to tell the script something like: if the portal is empty just create a new record in the lineItem.

In other words:

-my script goes to the last portal row and collect some variables.

-it goes to the line item, create a new record and sets a few fields with those variables.

-Back to the portal and a New window opens with the last item and present what's in there for verification and completion of the items qty, details etc...

How can I tell my script if the portal is empty just create a new record or ELSE do the working script?

I'M LOST. PLEASE HELP

Thank you.

If Count(Related::field) > 0

//not empty

else

//empty

endif

does this help?

IsEmpty() is supposedly better optimised than Count() when checking for related records.

If [ not IsEmpty( related::field ) ]

I tried "is empty" but because I can't (and don't want to) create new record from the portal it seems I can't select a field for the empty calc. And its the same for the count.

Any other idea?
