## Interface DynamicCriteria

-     public interface DynamicCriteria

  If a property indicates it has support for "dynamic criteria" it means that values in the criteria may be dynamically derived from the current `Canvas.ruleScope` using `Criterion.valuePath`.

  In other words, it allows criteria to be declared using values from nearby drawn components, via the `Canvas.ruleScope`. Values are pulled from the ruleScope via setting `Criterion.valuePath` When values drawn from the ruleScope change, the component where dynamicCriteria is declared will be notified and automatically use the new value

        public void onModuleLoad() {

             TextItem lifeSpan = new TextItem("lifeSpan");
             lifeSpan.setDefaultValue(45);

             final DynamicForm theForm = new DynamicForm();
             theForm.setID("theForm");
             theForm.setItems(lifeSpan);

             AdvancedCriteria initialCriteria = new AdvancedCriteria("lifeSpan", OperatorId.GREATER_THAN);
             initialCriteria.setValuePath("theForm.values.lifeSpan");

             ListGrid lg = new ListGrid();
             lg.setAutoFetchData(true);
             lg.setDataSource(AnimalXmlDS.getInstance());
             lg.setInitialCriteria(initialCriteria);
             lg.setWidth(600); lg.setHeight(400); lg.setTop(50);

             VLayout vl = new VLayout();
             vl.addMembers(theForm, lg);
             vl.draw();
        }
