Hi everyone, quick question about the ReferenceInsertionEventHandler: is it supposed to be called on a variable called into a #foreach loop (or even on the variable defining the foreach loop)?
For example:
public class IsThisAVelocityBug {
public static void main( String[] args ) {
String template1 = "${otherVariable}\n";
String template2 = "#foreach($test in
$testing)\n${test.something}\n${otherVariable}\n#end";
VelocityEngine veloctiyEngine = new VelocityEngine();
VelocityContext velocityContext = new VelocityContext();
EventCartridge eventCartridge = new EventCartridge();
velocityContext.attachEventCartridge( eventCartridge );
eventCartridge.addReferenceInsertionEventHandler( new
ReferenceInsertionEventHandler() {
@Override
public Object referenceInsert( String reference, Object
value ) {
System.out.println( "Inserting : " + reference
);
return reference;
}
} );
System.out.println( "template1" );
veloctiyEngine.evaluate( velocityContext, new StringWriter(),
"template1", template1 );
System.out.println( "template2" );
veloctiyEngine.evaluate( velocityContext, new StringWriter(),
"template2", template2 );
}
}
Here is the output:

template2
Why is it never called on any inserted variable in the template2?
