Description

When an UploadProgressBar component is removed, this exception is thrown: java.lang.IllegalStateException: No Page found for component

There is a getPage() call inside an attribute modifier that is registered on the form:
form.add(new AttributeModifier("onsubmit", true, new Model<String>() {
.... getPage() ....
}

Obviously one must remove the attribute modifier from the form when removing the UploadProgressBar.
