[NoPersist] in @set/getprofilefield

I am missing something embarassingly obvious …

I am trying to make use of this undocumented feature using two forms:

Form1 has an action with

T := “xxxxxxxxxx”;

@SetProfileField([NoPersist];“T”;@UserName)

and Form2 has an editable field defaulting to

@GetProfileField([NoPersist];“T”;@UserName)

but nothing appears, the field is blank.

I replaced the set in Form1 with

@SetProfileField([NoPersist];“T”;“xxxxxxxx”;@UserName)

with no success (and no error …)

I searched the forum and it looks I am the only who ever had a problem with this.

thank you
