Issues Encountered:

• The filtered set of options is not reflected on the UI (dropdown widget) properly, stay the same though the element model linked to the widget has changed options to the filtered set. I used a stream for the current filtered options set, but the propagation of cascading filter on the model is correct but on the UI it randomly propagates, changing one field other fields resets and other doesn’t reset based on new evaluated set of the elements they depends on
• An Action Hide/Show is not reflected on the UI, although the action is in effect.
