Filtering according to Etype when using Reference relation [message #1821443]

Hi,

I have noticed that when I use "Reference" relation in my metamodel (ECORE) between one element and another, the selection of possible elements in the actual model is not filtered according to the "EType" field.
However, when I use "B-directional Reference" in my metamodel, the selection of possible element IS filtered according to the "EType" field. This is a user-friendly feature.

Can the filtering be applied to the "Reference" relation as well? If there's a way to activate it, I would love to know. Otherwise, it would be nice if this will be implemented in a future version.

Thank you,
Avi

Hello,

Can you provide a screenshot because I do not understand what you mean or where your are looking for actual model and filtering.

Best regards,
Steve

Hi Steve,

First, it seems that my initial explanation was wrong: the difference seems to be the selection of item for a reference with no multiplicity (only one element allowed), which has no filtering according to type, and between selection of items for a reference with multiplicity, which automatically filters only appropriate elements (based on type).

I'm attaching two screenshots.
In noFiltering.png you can see the "Select" dialog which appears when I pressed the "..." button at the bottom of the screen (trying to select an existing Threatallocation relation). You can see that I am asked to "Please select a valid 'ThreatAllocationRelation'", and if I expand the model in the dialog, I get all entities (not just those of "ThreatAllocationRelation" type).

In filteringWorks.png you can the dialog which appears when I pressed the "..." button at the bottom of the screen (trying to select an existing Threatallocation relation). The choices are automatically filtered according to the type of the reference.
It will be nice to have the same/similar filtered screen (of filteringWorks.png) instead of the general "select" screen (of noFiltering.png).

Thank you,
Avi

Hello,

Ok I see what you mean now, unfortunately we have not scheduled to work on this evolution for the moment. Note that if you want you can implement your own custom widget if you want to modify the selection dialogs [1].

Best regards,
Steve
