Hi

Your problem is far from clear but "only once" usually has two approaches

a) use a Set so that there is only one element from which to do something once

b) use a helper with at least one Class-typed argument so that the multiple invocations of the helper retuirn the same value.

Hello Ed,

Thank you for your quick reply.

Sorry if it was not clear.
What I try to do is to find is it exist in my set of Foobar, one instance who has the property type equal to 'foo'. And the same in the case of 'bar'.
I am speaking about only once, meaning that even if I have several instance that has the value 'foo', I want to generate the text 'This is foo.' once and not as much as instances with this value (as in my 'solution').
