hello Richard
I already have a class with tons of static methods that return
strings, collections, content nodes, whatnot.
To wrap all that including the method result I find a bit daunting,
especially because the previously described method will take care of
it nicely. But I don't know how to use that in combination with the
sharedVariables feature.
For now I just created an extension to FreemarkerHelper to fix it:
public class VtkFreemarkerHelper extends FreemarkerHelper {
@Override
protected void addDefaultData(Map<String, Object> data, Locale
locale, String i18nBasename) {
super.addDefaultData(data, locale, i18nBasename);
BeansWrapper wrapper = BeansWrapper.getDefaultInstance();
TemplateHashModel staticModels = wrapper.getStaticModels();
try {
TemplateHashModel vtkUtilStatics =
(TemplateHashModel)
staticModels.get("nl.vpro.magnolia.module.vprotemplatingkit.util.VtkUtil");
data.put("vtkUtil", vtkUtilStatics);
} catch (TemplateModelException e) {
e.printStackTrace();
}
}
}
