Constraint problem updating 3.2 preview to 3.2 community

[jarrett]

A custom constrain we wrote that returns the members of a group fails during start up after upgrading 3.2 preview to 3.2 community. Java is not my strong suit so any help would be appreciated. I think all the relevant information has been included, if I've missed anything please let me know.

Excerpt from faces-config-custom.xml

<managed-bean>
        <description>Group Member Constraint</description>
        <managed-bean-name>GroupMembersConstraint</managed-bean-name>
        <managed-bean-class>com.efoundry.alfresco.constraints.GroupMembersConstraint</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
</managed-bean>‍‍‍‍‍‍

Excerpt from model:

<!–  seed value for Members of the Analyst Group –>
<constraint name="ygwf:AnalystConstraint" type="com.efoundry.alfresco.constraints.GroupMembersConstraint">
        <parameter name="allowedValues">
                <list><value>GROUP_Analyst</value></list>
        </parameter>
</constraint>‍‍‍‍‍‍

Excerpt from constraint:

    public List<String> getAllowedValues() {
        logger.info( "getAllowedValues()" );
        System.out.println("getAllowedValues()");
        ArrayList<String> list = new ArrayList<String>();

        List<String> groupMembers = super.getAllowedValues();
        groupMembers = getMemberList( groupMembers.get(0) );

      PersonService personService =  Repository.getServiceRegistry(FacesContext.getCurrentInstance()).getPersonService();
      NodeService nodeService =  Repository.getServiceRegistry(FacesContext.getCurrentInstance()).getNodeService();

        for( String memberName : groupMembers ) {
           StringBuffer sb = new StringBuffer();
           sb.append( memberName );
           sb.append( " - " );
           NodeRef memberNodeRef = personService.getPerson( memberName );
           sb.append( nodeService.getProperty( memberNodeRef, org.alfresco.model.ContentModel.PROP_FIRSTNAME ) );
           sb.append( " " );
           sb.append( nodeService.getProperty( memberNodeRef, org.alfresco.model.ContentModel.PROP_LASTNAME ) );
           /*sb.append( " (" );
           sb.append( groupMembers.get(0) );
           sb.append( ")" ); */
           
           list.add( sb.toString() );   
        }

        return list;
    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

[jarrett]

Would having the full source to the constraint be beneficial to anyone? Or is there a better way to query group members so we don't have to rely on this constrain any longer?

The error tells you that FacesContext.getCurrentInstance() is null.

That should mean that, when this class is called, no one is "browsing" your Alfresco.
FacesContext is not null when someone is surfing on the application.
When is this error raised ? At startup ? When going to some web page ?
Can you describe it more precisely ?
