hello matthias,
my previous message consists of two independent parts:
@unselectedLabel
and
@dynamic items
within "@dynamic items" i just provided the sample source code to solve the
problem of stephen (the question concerning dynamic items).
-> the sample source code is not connected with the scenario i mentioned
within "@unselectedLabel" (the "discard"-topic).
regards,
gerhard
