>An alternative to while is to do a recursive loop similar to functional programming
I have successfully defined a ui:Operations subclass that recurses based on count and maximum count Arguments defined in SPIN constraints. The ui:Operations subclass is called from the ui:prototype of a ui:Services subclass. Are there examples of: 1. returning a value from a ui:Operations subclass 2. assigning a variable the value of the result of a ui:Operations subclass 3. updating an Argument in Pass By Reference style On Tuesday, August 6, 2019 at 7:56:30 PM UTC-4, Holger Knublauch wrote: > > All queries in SWP, such as the result set of a ui:forEach, are computed > at once, i.e. there is no way to dynamically change the loop based on > things happening inside of the loop.
