Here is my flowscript :
function callRestaurantMainSearch() {
var restTypes = new Array(4);
restTypes[0] = new Packages.de.emld.hibernate.wlan.RestaurantType("Italian"
, 1);
restTypes[1] = new Packages.de.emld.hibernate.wlan.RestaurantType("German"
, 2);
restTypes[2] = new Packages.de.emld.hibernate.wlan.RestaurantType("French"
, 3);
restTypes[3] = new Packages.de.emld.hibernate.wlan.RestaurantType("Chinese"
, 4);
var form = new Form("forms/restaurant_main_search.xml");
form.lookupWidget("type").setSelectionList(restTypes, "id", "name");
form.showForm("forms/restaurant_main_search.xhtml");
}
My class is a Pojo with getId and getName methods.
My form xml is :
<fd:field id="type">
<fd:label>Type</fd:label>
<fd:datatype base="string"/>
<fd:selection-list />
</fd:field>
</fd:widgets>
What is wrong ?
Thanks !
Elad

Two possibilities come to mind:
A) use the src attribute and make it point to a pipeline that would query the
Hibernate datastore and output some XML. You don't have to have Hibernate
output XML, as you wrote: you can have a flowscript function do the query and
produce XML via a template page (JXTG or Velocity). Or even an XSP page.
B) possibly simpler:
var form = new Form("formdef.xml");
var list = hibernateSession.find("from ...");
form.lookupWidget("widget-id").setSelectionList(list, "id", "name");
form.showForm("form-template");
HTH,
Ugo
