[CSS] Filter on fields of type [message #1724523]

Suppose I have a profile "Status" with a stereotype property isResolved:Boolean.
If I want to color an "unresolved" Port orange, I can apply the Status stereotype to that Port and define the following CSS rule.

Port[appliedStereotypes~="Status"][isResolved=false] {
	fillColor : orange;
}

This works fine.

It is unclear how to support deeper nesting.
Suppose I want to color a Port in case its Type has a Status Unresolved.
As far as I know, there is no way to implement this indirection, is there?

One can extend the known CSS fields of Port e.g. typeIsUnresolved.
This only works for a profile deployed through a bundle (in order for the bundle to also register the correct extensions).
It is not supported in the typical scenario where a dynamic profile is directly applied from the workspace itself.

Is there a way to do this anyway?

Hi Johan,

This is indeed not supported. The CSS grammar doesn't provide enough flexibility to implement this without breaking the specification. We might be able to implement that with e.g. OCL Queries, stored in a separate Query model and referenced from the Stylesheet. This would allow dynamic customization for advanced scenarios, but CSS itself is not sufficient

Regards,
Camille
