Voici le code source générant l'erreur :
CustomManageTaskDialog customManageTaskDialog = (CustomManageTaskDialog) FacesHelper.getManagedBean(FacesContext.getCurrentInstance(), "ManageTaskDialog");
Cette ligne me donne l'erreur suivante :
A system error happened during the operation: org.alfresco.web.bean.workflow.ManageTaskDialog cannot be cast to ………… CustomManageTaskDialog
le code de la classe CustomManageTaskDialog
public class CustomManageTaskDialog extends ManageTaskDialog{………………………… }
Quelqu'un a-t-il une idée?Merci pour vos réponses

Enfin, surchargez l'implémentation du bean "ManageTaskDialog" (définition dans faces-config-beans.xml) en appelant votre classe CustomManageTaskDialog

cela ne marche pas, je ne sais pas pour quoi le FacesHelper n'arrive pas à instancier ma classe Customizée. Peut-être par ce que je mets les beans jsf dans un fichier face-config.xml dans META-INF, du jar généré puisque je travaille avec des AMPs et je suis dans l'obligation de suivre cette démarche.
je ne veut rien changer au fichier faces-config-bean.xml interne d'alfresco .

Code managedBean customManageTaskDialog du faces-config.xml; le même que celui de ManageTaskDialog dans faces-config-beans.xml
<managed-bean> <managed-bean-name>customManageTaskDialog</managed-bean-name> <managed-bean-class>alfresco.module.gestionCourrier.gestionCourrierSortant.UI.managedBeanDialog.CustomManageTaskDialog</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> <managed-property> <property-name>nodeService</property-name> <value>#{NodeService}</value> </managed-property> <managed-property> <property-name>fileFolderService</property-name> <value>#{FileFolderService}</value> </managed-property> <managed-property> <property-name>searchService</property-name> <value>#{SearchService}</value> </managed-property> <managed-property> <property-name>navigator</property-name> <value>#{NavigationBean}</value> </managed-property> <managed-property> <property-name>browseBean</property-name> <value>#{BrowseBean}</value> </managed-property> <managed-property> <property-name>dictionaryService</property-name> <value>#{DictionaryService}</value> </managed-property> <managed-property> <property-name>namespaceService</property-name> <value>#{NamespaceService}</value> </managed-property> <managed-property> <property-name>workflowService</property-name> <value>#{WorkflowService}</value> </managed-property> <managed-property> <property-name>avmService</property-name> <value>#{AVMLockingAwareService}</value> </managed-property> <managed-property> <property-name>avmSyncService</property-name> <value>#{AVMSyncService}</value> </managed-property> </managed-bean>
Surcharge de ManageTaskDialog : Dans CustomManageTaskDialog j'ai ajouté la méthode suivante :
public void removePackageItem(String nodeRef) { System.out.println("CustomManageTaskDialog.removePackageItem => nodeRef= "+nodeRef); if (this.packageItemsToAdd != null && this.packageItemsToAdd.contains(nodeRef)) { // remove the item from the added list if it was added in this dialog session this.packageItemsToAdd.remove(nodeRef); if (LOGGER.isDebugEnabled()) LOGGER.debug("Removed item from the added list: " + nodeRef); System.out.println("Removed item from the added list: " + nodeRef); } else { // add the node to the list of items to remove if (this.packageItemsToRemove == null) { this.packageItemsToRemove = new ArrayList<String>(1); } this.packageItemsToRemove.add(nodeRef); if (LOGGER.isDebugEnabled()) LOGGER.debug("Added item to the removed list: " + nodeRef); System.out.println("Added item to the removed list: " + nodeRef); } // reset the rich list so it re-renders this.packageItemsRichList.setValue(null); }
et j'ai rendu la méthode updateResource comme public au lieu de protected
et Enfin le code d'appel de toute cette usine de traitement :
CustomManageTaskDialog customManageTaskDialog = (CustomManageTaskDialog ) FacesHelper.getManagedBean(FacesContext.getCurrentInstance(), "CustomManageTaskDialog "); customManageTaskDialog.removePackageItem(nodeRef.toString()); removeFile(); customManageTaskDialog.updateResources();
Le problème c'est que je ne sais pas très bien comment supprimer un fichier du workflow et ajouter un autre à sa place en exploitant la classe CustomTaskManageDialog ??????????????
Merci pour le Help
