I have a plugin that needs to add code completion for an undeclared variable. To do so I try to implement my own goal factory.
I am able to set break points, and start a debugging session. But it seems like the plugin is never called, a break point is never reached when I start to edit a php file.
I have no idea whether the plugin.xml is correct:
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
    <extension point="org.eclipse.php.core.goalEvaluatorFactories">
        <goalEvaluatorFactories
               class="my.MyEvaluatorFactory"
               priority="100"
               id="my.MyEvaluatorFactory"
               name="My test"
               nature="org.eclipse.php.core.PHPNature" />
    </extension>    
</plugin>
public class MyEvaluatorFactory implements IGoalEvaluatorFactory {…}
public class MyEvaluator extends GoalEvaluator {…}
I've modelled it according to 
http://wiki.eclipse.org/API_Document_for_Extension_Points_PDT_2.0#PHP_Evaluator_Factory, but I am not sure if these examples are still correct. When I look in the aspectPDT sources, I cannot find any of the demonstrated extension points. :S
So the question is: why is my Evaluator never invoked?
