Creation d'ecran pour Workflow [Résolu]

Bonjour,

je souhaite pouvoir développer des écrans de Workflow. Après avoir lu de nombreux exemples sur les forums Françcais et Anglais, j'avoue avoir compris un peu la phylosophie de la chose. Là ou cela se gate, c'est que je souhaite réaliser un écran de Worlflow me permettant de sélectionner une liste de lecteurs et une liste d'approbateurs. Je ne sais pas comment coder la chose.

J'ai trouvé l'exemple suivant  dans le repertoire webappsalfrescoWEB-INFclassesalfrescoworkflow (fichier workflowModel.xml) : 

<type name="wf:submitReviewTask">
   <parent>bpm:StartTask</parent>
   <mandatory-aspects>
       <aspect>bpm:assignee</aspect>
   </manadtory-aspects>
</type>‍‍‍‍‍‍
ainsi que l'exemple suivant dans le reperoire webappsalfrescoWEB-INFclassesalfresco (fichier web-client-config-properties.xml)

<config evaluator="node-type" condition="bpm:startTask" replace="true">
      <property-sheet>
         <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
         <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" />
         <show-property name="bpm:workflowPriority" />
         <show-property name="bpm:workflowDueDate" />
         <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />
         <show-association name="bpm:assignee" />
      </property-sheet>
   </config>

  <!– Review and Approve workflow tasks –>

   <config evaluator="node-type" condition="wf:submitReviewTask" replace="true">
      <property-sheet>
         <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
         <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" />
         <show-property name="bpm:workflowPriority" display-label-id="wf_review_priority" />
         <show-property name="bpm:workflowDueDate" display-label-id="wf_review_due_date" />
         <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />
         <show-association name="bpm:assignee" display-label-id="wf_reviewer" />
      </property-sheet>
   </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
Or cet exemple me permet d'attribuer uniquement dans mon Workflow un seul relecteur. Mon objectif, à partir du premier écran du workflow et de définir une liste de relecteurs, ainsi qu'une liste d'approbateurs et éventuellment une liste d'autres acteurs.

Si quelqu'un a une idée, car je pêche complètement.

Une petite question en passant.

Qu'est ce qu'un <mandatory-aspects> et <mandatory>. Quel est leur rôle exacte ?

Merci d'éclairer ma lanterne.

Re: Creation d'ecran pour Workflow [Résolu]

Pour ceux que ca interesserait, j'ai réécri aujourdhui la fonction bpm:assignees pour pouvoir réaliser l'assignation de tâche à des relecteurs et des approbateurs. Pour pouvoir définir mon propre Workflow, je me suis inspiré des modèles de workflow existant dans Alfresco et j'ai fini par créé le fichier modèle suivant lprwfModel.xml

<?xml version="1.0" encoding="latin9"?>

<model name="lwf:lprwfmodel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

   <!– Optional meta-data about the model –>
   <description>My Workflow Documents Model</description>
   <author>Huberson David</author>

      <namespace uri="lwf.workflowModel" prefix="lwf"/>
   </namespaces>

   <types>

      <type name="lwf:submitReviewAndApprovalTask">

            <property name="lwf:requiredReviewPercent">

               </constraints>
            </property>
         </properties>
         <mandatory-aspects>

Ce modèle est encore incomplet car il ne permet que la première étape de validation, la relecture de documents uniquement.

puis j'ai rajouté ces quelques lignes dans le fichier web-client-config-custom.xml

   <!– Workflow Configuration –>

Bonjour,

La balise permet <mandatory-aspects> permet d'indiquer les aspects obligatoires qui seront ajoutés à un type de document. Et évidemment, ma balise <mandatory> permet d'indiquer qu'un élément est obligatoire.
