Update Slice version in pom.xml and set to 4.0.0, e.g.

Code Block
... <dependency> <groupId>com.cognifide.slice</groupId> <artifactId>slice-core-api</artifactId> <version>4.0.0</version> </dependency> ...

Update Activator. There's no need to setup context any more - the only object you need to create is InjectorRunner. More details here: Writing activator - 4.0.
1. Remove ContextScope object.
2. BASE_PACKAGE and BUNDLE_NAME_FILTER are now arguments of InjectorRunner's constructor - move them there.

Context has been simplified - the ContextProviderFactory does not longer exist. A snippet of code needed to get an injector in servlets or OSGi services should be rewritten as follows:

Code Block

//old one - Slice 3.2
public void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) {
    InjectorWithContext injector = injectorsRepo.getInjector("appName");
    ContextProviderFactory contextProviderFactory = injector.getInstance(ContextProviderFactory.class);
    SimpleContextProvider simpleContextProvider = contextProviderFactory.getSimpleContextProvider();
    ContextFactory contextFactory = injector.getInstance(ContextFactory.class);
    simpleContextProvider.setContext(contextFactory.getServletRequestContext(request, response));
    injector.pushContextProvider(simpleContextProvider);
    try {    
        ModelProvider modelProvider = injector.getInjector().getInstance(ModelProvider.class);
        //do your stuff
    } finally {    
       injector.popContextProvider();
    }
}

//new one - Slice 4.0
public void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) {
    try (InjectorWithContext injector = InjectorUtil.getInjector("myApp", request)) {      
        ModelProvider modelProvider = injector.getInstance(ModelProvider.class);      
        // do somethingyour cleverstuff
with the model
    }
}

//new one in Java6 - Slice 4.0
public void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) {
    InjectorWithContext injector = InjectorUtil.getInjector("myApp", request);
    try {      
        ModelProvider modelProvider = injector.getInstance(ModelProvider.class);      
        // do something clever with the model
    } finally {
        injector.close();
    }
}

Link API has been removed. If you want it back, fell free to take it out of Slice 3.2.0 source code: https://github.com/Cognifide/Slice/tree/3.2.0. You will need to register a link module (see example) in the list of your modules in activator.
