[NTG-context] problem with \processaction

Dear list, I have the following sample: \def\SystemUser{whoami} \def\CheckUser{\processaction[\SystemUser][whoami=>whm]} \starttext \doifelse{\CheckUser}{whm}{This is the right user.} {This is the wrong user.} \doifelse{\SystemUser}{whoami}{This is the right user.} {This is the wrong user.} \SystemUser\ is \CheckUser \stoptext Why doesn’t the first \doifelse work? What am I missing there? Many thanks for your help, Pablo -- http://www.ousia.tk
