Embedding a Magritte component in another component

Greetings, I have built a component called "VeComponent", with an embedded Magritte component. The code for rendering looks like: VeComponent>>renderContentOn: html html render: self model asComponent addValidatedForm; yourself. html submitButton callback: [self answer: someValue]; text: 'Done' To test this code I call it from aWATask like this: go>> returnValue := self call: aVeComponent. self halt. This works, I get to the halt. If I embed aVeComponent in another component then it appears that the "self answer: someValue" in VeComponent>>renderContentOn: does not work. What I observe is that clicking on the 'Done' button results in the re-displaying of aVeComponent. How is it that the code works when called from aWATask but it does not work if it is contained in another component? Can anyone explain what I am doing wrong? Many Thanks, Frank
