org.apache.cocoon.woody.datatype
Class FlowJXPathSelectionListBuilder

java.lang.Object
  org.apache.cocoon.woody.datatype.FlowJXPathSelectionListBuilder

All Implemented Interfaces:

Contextualizable, SelectionListBuilder

public class FlowJXPathSelectionListBuilder
extends Object
implements SelectionListBuilder, Contextualizable

Builds a selection list that will take its values from the flow page data. The items list and, for each item, its value and label, are fetched using JXPath expressions.

If an item has no label, its value is used as the label.

Example:

   <wd:selection-list type="flow-jxpath"
       list-path="selectList" value-path="value" label-path="label"/gt;
 

Flow script:

   var data = {
      selectList: [{value:3, label:"three"}, {value:4}]
   };
   form.showForm("form.html", data);
