It depends on the type you have used for the status property.
If you have used a category to represent the status then you could use the r:categorySelector component, however, currently this will allow you to select any category in the system i.e. you can't limit it to a particular category.
We will be working to improve this in the 1.3 timeframe as well as working on value constraints for properties which will include "list of available values" functionality.
If the status property is just a text field you can just use a normal drop down box represented by the standard JSF h:selectOneMenu component. An example of this is in /projects/web-client/source/web/jsp/wizard/new-rule/details.jsp. The component in this case calls getTypes() in NewRuleWizard to retrieve the values. This method has to return a List of SelectItem objects.
Hope this helps.
