阅读更多关于 How to reference component inside a composite component when using a converter

问题 I have a composite component that mainly consists of a selectManyCheckbox component. As it should be designed in a generic way I pass in selectItems, ajax handling etc. from the calling level using <composite:insertChildren/> This works quite well for most of the stuff.
