Ok, I thought the default workflows send e-mail to. What I did is creating a new workflow. I used the book from Wrox: Professional Alfresco. When I place my script in an other place in the workflow the mail is sent. So there must be something wrong with the code I got from the book?Here is the procesdefinition:
<process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="mywf:myReviewAndApprove">
<swimlane name="initiator"></swimlane>
<swimlane name="reviewer">
<assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
<actor>#{bpm_assignee}</actor>
</assignment>
</swimlane>
<start-state name="start">
<task name="mywf:mySubmitReviewTask" swimlane="initiator"></task>
<transition name="" to="review"></transition>
</start-state>
<task-node name="review">
<task name="mywf:myReviewTask" swimlane="reviewer"></task>
<transition name="approve" to="approve"></transition>
<transition name="reject" to="reject"></transition>
</task-node>
<node name="approve">
<event type="node-enter">
<script>
<variable name="reviewResult" access="write"></variable>
<expression>
reviewResult = "approved";
</expression>
</script>
</event>
<transition to="completed"></transition>
</node>
<node name="reject">
<event type="node-enter">
<script>
<variable name="reviewResult" access="write"></variable>
<expression>
reviewResult = "rejected";
</expression>
</script>
</event>
<transition to="completed"></transition>
</node>
<task-node name="completed">
<event type="node-enter">
<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
<script>
var mail = actions.create("mail");
mail.parameters.to = initiator.properties["cm:email"];
mail.parameters.subject = "Review Task " + bpm_workflowDescription;
mail.parameters.from = bpm_assignee.properties["cm:email"];
mail.parameters.text= "The article has been " + reviewResult + ".";
mail.execute(bpm_package);
</script>
</action>
</event>
<task name="mywf:myCompleteReviewTask" swimlane="initiator"></task>
<transition name="" to="end"></transition>
</task-node>
<end-state name="end"></end-state>
</process-definition>
Here is the workflow-model:
<model name="mywf:myReviewAndApproveModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
<description>Example Review And Approve Task Model</description>
<author>Alfresco</author>

<types>

<parent>bpm:workflowTask</parent>
<mandatory-aspects>
<aspect>bpm:assignee</aspect>
</mandatory-aspects>
</type>
</types>
</model>
I don't get any error messages, the mail just isn't sent out.
