Re: updating components on Page from ModalWindow's internal Page's components
Not sure if it is relevant, but to update images using ajax you need to generate a unique URL by adding a timestamp or random number to it.

Re: updating components on Page from ModalWindow's internal Page's components
Are you sure that the newly added image has different src attribute (e.g. adding a timestamp) than the old one?

Re: updating components on Page from ModalWindow's internal Page's components
I came to a similar conclusion shortly before reading this. So now I seem to be updating in the correct place, but I'm having trouble getting the image component to swap out within the onClose(AjaxRequestTarget pTarget) Inside the ModalWindow, assuming I previously did a setOutputMarkupId on the original component, something like this works: Component newComponent = new Component(); origComponent.replaceWith(newComponent); origComponent = newComponent; Should I be able to do something similar inside the onClose, and get Ajax to replace the component? I add both the old and the new object to the AjaxRequestTarget w/ addComponent, but it doesn't seem to be updating properly...
