Description Felix Dorner

Hi,

it often that the workspace image for a domain object depends on certain attributes of the object. This results in lots of 'conditional style' elements. It would be so much simpler if the workspace path value was an expression. As an example, I have an object that has an enum attribute. For each literal value of the enum, I have an image, <literal>.png. If the path was an expression, I could just do something like workspacePath=aql:'path_prefix' + self.enumAttrib + '.png' (not sure if that's really aql, but you get the point). Compare that to the N conditional style elements needed at the moment.

And another disadvantage of using multiple conditional styles that I need to copy/paste all the other properties, such as label size, alignment and whatever.

Hello thank you for suggestion of enhancement.
Effectively, it would be interesting to have an expression to define the image path.
Nevertheless, I don't think this enhancement will be added in the roadmap soon particularly because you already have the ability to functionally achieve what you want eventhough effectively with more pain that you would like to.

BTW, there are other elements that point to images and these ARE already interpreted as an expression, e.g. DecorationDescription, so I'd guess it would be very easy to duplicate that behaviour.
