Hi, I have a requirement to present the background of specific property based on its value or depending on other object properties. Currently I can define cssClass as described https://isis.apache.org/guides/ugfun/ugfun.html#_ugfun_ui-hints_action-icons-and-css at development time.
It would be great if I could define a kind of specification class similar to https://isis.apache.org/guides/rgant/rgant.html#_rgant-Property_mustSatisfy which returns cssClass in runtime. It could look like this public class Customer { @Property(cssSpecification=MyCssClass.class) public String getFirstName() { ... } ... } public class MyCssClass implements CssSpecification { public String cssClass(Object obj) { if (((Customer) getFirstName())==null) return "x-test"; return "x-firstName-not-empty"; } } Make this requirement sense, and if so, any hints how I could implement this? Regards,Vladimir
