/**
 * This is a hack. This method will add a new page to the current form definition
 * in context. Ideally, this entire class needs to be refactored. There are traces
 * of controller, view and model responsibilities in this class.
 * Also, instead of trying to pick out elements from the tree widget itself, a selection model 
 * of some sort should be used. That would make this entire process less hideous
