[jbpm-users] Human Tasks showing marshalled arguments in FTL

[Darin Wilcox]

Hi,

I'm running jbpm 5.3.0.Final on JBoss 7.1.1 along with an H2 database.

Things are working well, but the arguments being consumed by the HumanTasks
are being displayed in the FTL as marshalled objects (see below):

I had to dig into the code jbpm-gwt-form code and modify the
TaskFormDispatcher.provideForm(FormAuthorityRef ref) near the bottom of the
method so it looks like this:

        if (input instanceof Map) {
            Map<?, ?> map = (Map) input;
            for (Map.Entry<?, ?> entry: map.entrySet()) {
                if (entry.getKey() instanceof String) {
                MarshalledContentWrapper val =
(MarshalledContentWrapper)entry.getValue();

                Environment env = EnvironmentFactory.newEnvironment();
                ContentMarshallerContext cmc = new
ContentMarshallerContext();
                ObjectMarshallingStrategy[] strats =
(ObjectMarshallingStrategy[])env.get(EnvironmentName.OBJECT_MARSHALLING_STRATEGIES);
                cmc.addStrategy(strats[0]); // Should only have one option
here...
                Object o =
ContentMarshallerHelper.unmarshall("org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy",
val.getContent(), cmc, env);

                renderContext.put((String) entry.getKey(), o);
                }
            }
        }

This change now results in:

Is this a bug or have I done something incorrect?

Thanks,
