Hi Bob,
this was a bug in the sml:PerformUpdate module. Cases in which the
argument was used as a string template {?arg1} failed to insert the
variable values correctly. This is fixed for the next release. As a
work-around, work-around the string template using something like
INSERT {?person rdfs:label ?newName}
WHERE {
?person a kennedys:Person .
?person kennedys:name ?name .
LET (?newName := smf:buildString("{?1}, ?arg1, {?name}"))
}
