Hi all,
in a template we are working on for a use case related to a dataset of cancer patients we need to represent :
- the interval (in weeks) passed between the date of first diagnosis and the beginning of the radiation therapy;
- the interval (in weeks) between the date of first diagnosis and the end of radiation therapy.
At the moment, we have modeled it by adding the CLUSTER “Timing - non-daily” in the “Procedure details” SLOT of the ACTION “Procedure” archetype and cloning the “Specific event” Cluster (that has 0…* occurrences) as shown in the figure. Then, we set the default value of the “Event name” to “Primary diagnosis” and limited the time units for the “Time offset” element to weeks.
That said, we have a problem in using the annotation feature of the Archetype Designer, as the annotations of the elements within the cloned Cluster (“Radiation end time”) seem to delete the annotations of the elements within the original one, so these get lost when the template is exported, no matter which format is used (.opt, web template, etc.).
Thus we are wondering whether this is the correct behaviour of the software in accordance with the specifications and therefore we are mistaking the modelling or it is instead a bug of the app to be taken into account.
Any opinion or suggestion is welcome 
Thanks!
