I’d like to hide certain elements on an outline if a user is not a member of any role…
Why doesn’t this work?
Many thanks
Subject: Why doesn’t this work? Hide when @Elements(@UserRoles)=0
I’m guessing it is because @Elements(@UserRoles) can’t ever be 0, because even if the only element is “”, that is one element. You could use @UserRoles=“” isstead, which would work because you will never have a blank element if there are any user roles at all.

But @UserRoles=“” is not working either (sorry, I should have mentioned that)
and @elements(@userroles) computed text does produce a zero.

“@elements(@userroles)”
It really should not (and it does not for me). @Elements should return 0 only, if it is fed a null string. That does not mean an empty string, but something like @Nothing.
Did you - to be on the sure side - close and reopen the client after granting or removing user roles? The problem you observe might just be down to caching.
Subject: RE: Why doesn’t this work? Hide when @Elements(@UserRoles)=0
Yes I did. And I deleted the cache.ndk
@UserRoles=“” or @Elements(@UserRoles)=0 does not work…
I read another posting somewhere on this site for another solution but I can’t get that working either:
!(@UserRoles *= “[Admin]”:“[RA]”:“[RB]”:“[RC]”)
I would really appreciate any other suggestions… MANY thx

“And I deleted the cache.ndk”
Won’t make a difference. Since the advent of Notes 6, I think I deleted my cache.ndk once. And I don’t mean once per week, as in 4, but really once in total.
I come to think - even more after you posted the results of the code suggested by Stephen - that either something in your hide-when-formula must be fundamentally wrong (is there anything else in it?) or that this outline is corrupted. It definitely should work either way suggested.

So it should work?
You’ve hidden outline entries when a user is not in any role?
I will create a new db from scratch and let you know what happens.
Subject: RE: Why doesn’t this work? Hide when @Elements(@UserRoles)=0
I realized I forgot that the ACL was set on the views from ‘all readers’ to all 3 specific roles… but it they were set to the roles to which I and my test IDs are members. Sorry if that makes a difference. I was careful to save changes to the design elements with the admin id that has access to all and test with my id which I would put in and out of roles…
ok so I created a new db from scratch and that worked as expected.
I think it’s working on my db now. Here’s what I did which I think worked:
-changed the ACL in the views to allow all readers
-saved the outline with no hide when formulas
-tested, worked as expected
-edited the outline and saved some of the individual entries with the following hide when formula:
num := 0;
num := @Elements(@UserRoles);
@If(num = 0; @True; @False)
-tested, worked as expected
-changed the view ACL back to exactly what I had before, based on roles
so far it appears to be working as expected.
Thanks for all your help!

Curious, is it on a server or local?
Hide when do have some odd results. I know I once had the following and it wouldn’t work
x := “1”;
@GetField(“Fieldname_” + x) = “”
Hoping it would hide if the value was blank. This would NOT work but if I changed it to:
@GetField(“Fieldname_1”) = “”
It would work. Anyway back to yours have you thought
I just added the following action to Outline I’m working on:
@Prompt([Ok];“test”;“# elements=[” + @Text(@Elements(@UserRoles)) + “] and they are [” + @Implode(@UserRoles;@NewLine) + “]”)
and got… Maybe it will tell you/us something
Subject: RE: Why doesn’t this work? Hide when @Elements(@UserRoles)=0
Thanks. I took myself out of all the roles and used your code on an outline entry.
cam up with ‘[0] elements and they are ’
This is on the server BTW.

Weird OK, so to try things. What happens in your hide when if you do the following
num := 0;
num := @Elements(@UserRoles));
@if(num = 0; @True; @False)
