migrating from 1.4 to 1.6.1 iteration over a List no longer works
-----------------------------------------------------------------
Key: VELOCITY-701
URL: https://issues.apache.org/jira/browse/VELOCITY-701
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.6.1
Environment: Linux, Sun Java 1.5
Reporter: chad davis
I have a template that references a List returned by a method on an Enum. The
method is defined as an abstract member of the enum. This used to work on 1.4,
but doesn't work on 1.6.1 I'm able to get it to work on 1.6.1 by changing the
abstract method to a regular method of the Enum, which is then overridden by
each instance of the enum. Here's the code that doesn't work.
Again, it seems to be the abstract modifier, becuase if I change that method to
something like
public List getMyList() { return new ArrayList(); }
And then just override it in my enum instances, everything works fine.
public enum Thing {
NUMBER_ONE( ){
public List<String> getInnerThings() {
//initialize innerThings if this is first time
if ( this.innerThings == null ) {
innerThings = new ArrayList<String>();
innerThings.add( "blah blah" );
innerThings.add("blah blah" );
}
return innerThings;
}
},
NUMBER_TWO( ){
public List<String> getinnerThings() {
//initialize innerThings if this is first time
if ( this.innerThings == null ) {
innerThings = new ArrayList<String>();
innerThings.add( "blah blah" );
innerThings.add("blah blah" );
}
return innerThings;
}
},
NUMBER_THREE( ){
public List<String> getinnerThings() {
if ( this.innerThings == null ) {
innerThings = new ArrayList<String>();
innerThings.add( "blah blah" );
innerThings.add("blah blah" );
}
return innerThings;
}
};
List<String> innerThings;
//This was an abstract method, but Velocity 1.6 quite working with it.
public abstract List<String> getinnerThings();
}
