How to update components using Ajax when ModalWindow closes?
Hi,
When a user clicks on an Image a ModalWindow pops up where users can upload
and change this picture. When the user has uploaded a new picture and click
"OK" in the ModalWindow I want it to close down and update the previous
Image with the new image. How ever I cannot get the Image to update using
Ajax (if I reload the page the I can see the new image). The image is
wrapped in a markupcontainer which has output markup id set to true. I try
to replace the image using markupcontainer.replace(new Image(..)) and I add
the markupcontainer to the target but nothing happens. This is the same
target that I use to close the modal window. What am I doing wrong?

I've managed to resolve it!
First of all I didn't add the markup container surrounding the image to the
same AjaxRequestTarget that closed the modalwindow (I don't add the markup
container to the AjaxRequestTarget at all). Instead I added a new
WindowClosedCallback to the ModalWindow. To its AjaxRequestTarget I do
"target.addChildren(MyPanel.this, Component.class)". This seems to resolve
it in combination with using NonCachingImage.

Using NonCachingImage (as Nino suggested) should be necessary:
otherwise the browser might cache your image and never ask for a the
new one. Can you post your code?

This doesn't help, the image still doesn't appear.
