Re: v17R5 bug?
Miyako, I’ll reply to Kirk’s long (and helpful) post with some more detail. There’s more than one way to skin a cat, I agree: but 4D shouldn’t crash if I ask it to search for a pointer, surely.

Re: v17R5 bug?
It is just a different work-around. I'd rather loop over the collection to solve it and use the right data structure. Note also collection.distinct() fails to remove duplicate pointers.

Re: v17R5 bug?
Changed the subject, I assume you mean 17R5, version 15 does not have dot notation. > On Jul 28, 2019, at 11:20 AM, Jeremy Roussak via 4D_Tech > <4d_tech@lists.4d.com> wrote: > > Is searching for pointers not allowed? I would assume no because 4D can't search collections for a pointer: $test:=New collection(->[Table]Field).indexOf(->[Table]Field) `Returns -1 Disappointing because you can search for pointers in a pointer array, but not in a collection. And the above gives -1 implying that the search was completed rather than an error to indicate it is not supported.
