I'm using Parsley 3.0 with the Flex extensions, but was wanting to use the spicelib syntax for executing a command group:

        Commands.asSequence()
                .create(LoadCachedCredentialsCommand)
                .create(LoginCommand)
                .lastResult(appInit_resultHandler)
                .error(appInit_errorHandler)
                .execute();

When doing it like this, I've noticed that injection with metadata in the commands do not work. Is this expected behavior? I assumed all the normal functionality with injection when defining the commands in the context would also work in this situation. But I wanted to confirm this to make sure I wasn't simply doing something wrong.

This is expected, as Spicelib itself does not know about Parsley. If you want your sequence to be managed by Parsley, you need to add it manually to the context:

var sequence:Command = Commands.asSequence()
                               .create(LoadCachedCredentialsCommand)
                               .create(LoginCommand)
                               .lastResult(appInit_resultHandler)
                               .error(appInit_errorHandler)
                               .execute();
var context:Context = ...;          
ManagedCommands.wrap(sequence)
               .execute(context);

See also here in the Parsley documentation.

  • Thank you. I did eventually find the same solution in the manual. Since then, I've discovered that, using this method, constructor injection, via InjectConstructor, does not work. It fails find a matching type of managed object. But property injection works fine. I guess, maybe, it's a bug... but something not difficult to work around. – user3204406 Jan 18 '14 at 18:17
