      • On studio, deploy a TCK component where in datastore, a property has an activeif that references a property that is not on the same form (see code exemple below to clarify).

      For example, a property visible on "Advanced" form has a @ActiveIf on a property that is only on "Main' form.

      @Data
      @DataStore("MyDS")
      @GridLayout({ //
              @GridLayout.Row({ "propMain" }), //
      })
      @GridLayout(names = GridLayout.FormType.ADVANCED, //
              value = { 
                      @GridLayout.Row({ "advanced" }), //
              })
      @Documentation("...")
      public class XDataStore implements Serializable {
          @Option
          @Documentation("...")
          private String propMain = "";
      
          @Option
          @Documentation("...")
          @ActiveIf(target = "propMain", value = "XXX")
          private String advanced;
      }
      

      will trigger the exception.
