[ Solved ] Spring bean injection in Custom mail workflow

[paride]

Hi all,
i'm experiencing some problems with a custom workflow (in Share) i'm developing on Alfresco Community 4.0.
The workflow is very simple:

1) The user inserts an e-mail address
2) The user selects an attachment
3) The user starts the workflow

This script creates the mail:

var l = bpm_package.children.length;
var mail = actions.create("mail");
mail.parameters.to = em_mailToAddress;
mail.parameters.subject = "You have a file to view! ";
mail.parameters.from = initiator.properties["cm:email"];
mail.parameters.text = "Kindly approve the document ";
if( l ==1 )
{
  mail.parameters.node=bpm_package.children[0];
  mail.execute(bpm_package.children[0]);
}
else
{
   mail.execute(bpm_package);
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In the file outboundSMTP-context.xml i changed the class reference in the bean id="mail", replacing
<bean id="mail" class="org.alfresco.repo.action.executer.MailActionExecuter"
with
<bean id="mail" class="org.alfresco.sample.CustomMailActionExecuter"

I had to add this custom class to manage attachments that are not supported in standard Alfresco.

Now to the point: everything works fine if i access alfresco explorer and then alfresco share to start the workflow.
But…if i don't access the explorer before, accessing directly to share, the workflow doesn't work!

I found that the problem is in the Faces Context that, in the second scenario, is found NULL.
The log proves that:

org.springframework.mail.MailPreparationException: Could not prepare mail; nested exception is java.lang.IllegalArgumentException: FacesContext must not be null
   at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:367)

In another discussion i found this:

"The problem here is that you are using beans that reference the JSF context. This is only initialised if you use the Alfresco Explorer client (a JSF app). The correct procedure is to use Spring injection of the bean definitions that you require for your action bean"

How can i do this? How can i find out what beans are involved?
The only thing i know is that the problem (obviously!!!) is the attachment and, precisely, i think that the Faces Context is needed when retrieving nodes from repository.
Hereunder the bean involved (outboundSMTP-context.xml)

 <bean id="mail" class="org.alfresco.sample.CustomMailActionExecuter"
      parent="action-executer">
      <!– <bean id="mail" class="org.alfresco.repo.action.executer.MailActionExecuter" –>
      <property name="mailService">
         <ref bean="mailService"></ref>
      </property>

      </property>
      <property name="fromAddress">
         <value>${mail.from.default}</value>
      </property>
      <property name="repoRemoteUrl">
         <value>${repo.remote.url}</value>
      </property>
      <property name="sendTestMessage">
         <value>${mail.testmessage.send}</value>
      </property>
      <property name="testMessageTo">
         <value>${mail.testmessage.to}</value>
      </property>
      <property name="testMessageSubject">
         <value>${mail.testmessage.subject}</value>
      </property>
      <property name="testMessageText">
         <value>${mail.testmessage.text}</value>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Finally i solved by my self, changing the strategy!

Rather than injecting the bean i needed, i changed the way i was getting the serviceRegistry, without using the FacesContext.
You can found the solution in this very helpful link: http://86anuj.blogspot.it/2010/03/different-approaches-of-accessing.html

Kind regards, Paride!
