Hi Nicolae,
I have tried to reproduce this but could not so far. Judging from the
source code this scenario could only happen if the selected
spl:predicate is null, but the dialog doesn't allow this to happen. I
tried it also with TopBraid 4.4 on Mac. If you have any more details on
the exact steps, then I would appreciate it. I will in any case wrap
this place with another if statement to make it safer.
The wizard is just a convenience feature, so if you can't make it work
you can still "manually" create new functions and web services. Look at
other examples on how this is done - essentially like with SPIN functions.
Thanks
Holger

Hi,
I try to create a new function with TBC 4.4.
Scenario:
Open Scripts/ create function/web service.
On adding an argument, I select an URI/IRI to an existing Property
type resource with range xsd:string, already used in other functions.
Click Ok in add-arg popup.
Result:
First attempt, NPE. Second attempt, it worked. Thrid, NPE.
Pls help,
Thanks
