How to generate a select list from a simpleType of a custom schema?

[Michael_Bell]

I created a new schema:

<?xml version="1.0"?>
<xs:schema
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://project.nuxeo.org/schemas/dev/cookbook/example/pap/process-request-form/"
  xmlns:area51="http://project.nuxeo.org/schemas/dev/cookbook/example/pap/process-request-form/"
  >

  <xs:simpleType name="vehicle_type">
    <xs:restriction base="xs:string">
      <xs:enumeration value="Car"/>
      <xs:enumeration value="Airplane"/>
      <xs:enumeration value="X-Plane"/>
      <xs:enumeration value="Ufo"/>
    </xs:restriction>
  </xs:simpleType>

  <xs:element name="parking_area" type="area51:vehicle_type"/>
</xs:schema>

The schema was imported via the extension point schema of TypeService:

<extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
    <schema name="area51" src="schemas/process_request_form.xsd" prefix="area51" />
</extension>

Additionally the schema was used for an user defined document type. This works.

Additionally I added a layout to the extension point types of TypeService. The layout was added via the extension point layouts of WebLayoutManager. This works too.

The problem is the widget which I created for the new layout:

<extension target="org.nuxeo.ecm.platform.forms.layout.WebLayoutManager" point="widgets">

 <widget name="type_of_vehicle" type="selectOneDirectory">

  <labels>
    <label mode="any">Vehicle type</label>
  </labels>
  <translated>true</translated>
  <fields>
    <field>area51:parking_area</field>
  </fields>

  <properties widgetMode="any">
    <property name="directoryName">area51:vehicle_type</property>
    <property name="localize">true</property>
    <property name="ordering">label</property>
  </properties>

 </widget>

</extension>

It is no problem to display the document but if I try to edit the document then an excpetion occurs:

stackTrace : javax.servlet.ServletException: failed to build option list for directory     area51:vehicle_type
             at javax.faces.webapp.FacesServlet.service(FacesServlet.java:277)

It would be nice if somebody could give me a hint, how to define the options.

Hi Michael,

The directoryName property is set to 'area51:vehicle_type'. It should be in fact the id of the directory you're using to build your list option. Right now Nuxeo looks for a directory called 'area51:vehicle_type'. You can replace it for instance by 'continent'.

[Michael_Bell]

So the widget type selectOneDirectory is completely wrong. Is there an alternative to create a select box which makes it possible to select one type? (I look for a way to create a select box like for "nature".)

[Laurent_Doguin]

SelectOneDirectory will indeed create a box like for nature. You'll get exactly the same if you replace

1. Is there any alternative without creating directories?

1. Using a custom widget instead of SelectOneDirectory.

First thanks for your patience. I didn't notice the meaning of directory. Second here are the links to the documentation and to an example (just for completeness)
