Problem bei Update einer DataList im Zusammenhang mit RemoteFormData

Author: novomind
Publication Date: 3/22/2013 14:20

Ziel ist das Hinzufügen oder Andern von Elementen einer DataList per Modul, wobei die Änderung direkt in der GUI gemacht werden soll, so dass diese sofort sichtbar ist und der Benutzer wählen kann, ob er speichert oder verwirft.

Der Zugriff auf die Elemente der Liste mit folgendem Code Fragment funktioniert, aber das Setzen der aktualisierten DataList führt zu einer UnsupportedOperationException. Kann hier jemand weiterhelfen?

Page page = ...;
operationAgent = context.requireSpecialist(OperationAgent.TYPE);
OpenElementDataFormOperation editDialog = operationAgent.getOperation(OpenElementDataFormOperation.TYPE);
RemoteFormData rfd = editDialog.perform(page);
RemoteFormField<?> categoryFormField = rfd.get(masterLanguage, CATEGORY_LIST);
FormDataList dataList = (FormDataList) categoryFormField.get();
// add element to list
IdProvidingFormData formData = ((SectionFormsProducer) dataList.getProducer()).create(sectionTemplate);
FormField<Number> catEntryIdField = (FormField<Number>) formData.get(null, "st_entryId");
catEntryIdField.set(Integer.valueOf(entryId));
dataList.add(formData);
categoryFormField.set(dataList); // -> führt zu UnsupportedOperationException
editDialog.setFormData(rfd);

Exception:
