Computed color expression to return R,G,B in one service call [message #1769419]

Hi,

This has bothered me for some time:

for a computed color, I invoke a service method which determines the color on some properties of the model. Since there are three expressions, (R,G,B), the service method is called 3 times, this just feels wrong. In my case it would be really better if I could return a single RGB string, such as one returned by org.eclipse.jface.resource.StringConverter.asString(RGB), so the service method is just called once, returning such a string. I have never seen the advantage to have a separate expression for each color component.

Hi Felix,
A corresponding enhancement exists on bugzilla : https://bugs.eclipse.org/bugs/show_bug.cgi?id=484125 with a specification. But, it was never included in a roadmap.
