Hello Janis,
Thank you for your suggestion, we will implement it in one of the future updates of the system.
For now, instead of deleting an artifact and recreating it, you can rename it through the authoring tool under the "General" settings of the artifact. Just click the name and you will be able to edit it. However - this won't affect the name if this artifact is used within another artifact, e.g an event used in a context. you will also have to edit the event's name in the context using it.

Regarding your problem - this is a matter of design. You can only derive one instance of an event. If you want you derived event to have values dependent on some condition, you will have to put this condition in the attribute expression itself (under Event Attributes).
Here is an example, to match your problem:
in the expression for the id attribute, write:
if x==2 then 1 else if x==3 then 2 endif endif

And if you want to derive the event only for specific values of x, in the condition of the event itself you can write x==2 OR x==3

Itai Peri

Hello

I have one request again and one (i think so) bug.
About request - it would be great if it would be possible to rename events,
epas, etc. from right mouse button menu not just delete it or replicate it.

About bug. When in some EPA you want to derive same event with different
attributes and conditions. For example, my epa wants to derive event
'DryingOutEvent' with attribute id=1 when condition x==2 is true. And when
condition is x==3 my epa (same epa) wants to derive same event
'DryingOutEvent' with attribute id =2.
So the problem is that it doesn't matter which condition is true, the event
'DryingOutEvent' always will have attribute id=2.

What is interesting.. if my first condition's first attribute were id=2 and
seconds id=1 then the event 'DryingOutEvent' always will have attribute
id=1.

Visualization for both:

Thanks a lot,
Jānis

Dear Miguel,

Yes, we will look into it and assess the efforts. In the meantime we will
try to provide a workaround.
Thank you!

Fabiana

Dear IBM team,

Please consider whether adding this to coming releases is a good idea. It
seems reasonable as it reads...

Dear Jānis,

Thanks so much for your feedback, appreciated.

I will re-route it internally to the dev teams to debate it and to ponder whether to add it to future releases

Kind regards,

Miguel

Hi FI-WARE,

I want to report about Proton issues/capabilities that i would like to ask u guys to implement!
First, i already spoke with developers. There is not allowed to pass a variable to array neither array cant be initiated with it. Currently array can take only constansts like

, but not varriables

.

Second, there is no built-in function DoubleToString() or just function that casts to String.

And third, there is no way to access n-th value in the aggregated array.

Thanks a lot,
Jānis.
