Hi Timo, Sorry I didn't see your email earlier. You can use ObjectParamRule to pass arbitrary objects as part of a CallMethodRule. However CallMethodRule rules actually invoke the target method when the xml end tag is reached, which might not be what you want if you *must* have the call made before addSetProperties. An alternative is to use FactoryCreateRule rather than ObjectCreateRule to create your object. You can then provide a custom ObjectCreationFactory which configures your new instance however it wants. Or you can write a custom rule, QuestionInitialiserRule, that makes the necessary call, and add it: Rule questionInitialiserRule = new QuestionInitialiserRule(...); digester.addObjectCreate(...); digester.addRule(..., questionInitialiserRule); digester.addSetProperties(...); .... A custom rule like this should be about 20 lines of code. I would think that using FactoryCreateRule is probably the best option given your description.
