You can do something like this: public class Crud { ... // all your code
@Inject private ComponentResources resources; @Inject private Block yourBeanEditorBlock; /** * A Block from the page to render instead of the normal BeanEditor. */ @Parameter(defaultPrefix = BindingConstants.LITERAL) private Block *overrideEditorBlock*; private Block *getChosenEditor* () { if (resources.isBound("*overrideEditorBlock*")) { return *overrideEditorBlock*; } else { return yourBeanEditorBlock; } } } in Crud.tml: <t:delegate to="prop:*chosenEditor*"/> and in your page: <t:crud object="mybean" ... > <t:parameter name="*overrideEditorBlock*"> // your components here </t:parameter> </t:crud> I didn't tested this specific code, but I have a component like this and it works.
