Building metadata based UI using RichRegion

Question

Hi,
I am building a metadata based UI, basically a Form Layout which will show different types of variables. The renderer of the variable value needs to be configurable.
This UI will be used as a framework to show/interview different kind of variables(like String, List, Map and more complex ones.)
The way I am trying to design it is to keep the renderer of each variable a region which the framework users can override(they can build their own renderers).
Effectively, I have to build a RichPanelFormLayout with multiple RichPanelLabelAndMessage children in it. If I take the approach of a renderer being a region, then I need to add RichRegion as a child of RichPanelLabelAndMessage.
Code snippet:
RichPanelFormLayout variablesForm = new RichPanelFormLayout();
for (String varName : zone.getVariableNames()) {
RichPanelLabelAndMessage varLayout = new RichPanelLabelAndMessage();
varLayout.setLabel(varName);
varLayout.setShortDesc("variable desc");
RichInputText it = new RichInputText();
it.setValue(configData.getVariableValue(varName));
varLayout.getChildren().add(it);
variablesForm.getChildren().add(varLayout);
Here instead of adding RichInputText, I want to add RichRegion which would encapsulate a dynamic region which in turn can contain the inputText for simple String variable OR other complex variables.
Can I achieve this?
This looks like the case of adding dynamic regions to my bean. The decision about the region is based on the variable type.
I did not find any example to programmatically add regions to a page.
Would appreciate any ideas/opinions.
Thanks and Regards,
Gaurav
