I have a simple Widget where the user can set its user picture. It has
a fileupload and shows the user image. So when the user wants to
change his user picture, he simply clicks on the fileupload chooses
picture and this is then send to the server. On the server side the
picture is safed as "userId".jpg where userId is a unique integer
associated with each user. So everytime the user updates his foto, his
file named "userId".jpg is simply overwritten, keeps its name and
after the fileupload succeeded on the client side in the "public void
onSubmitComplete(FormSubmitCompleteEvent event)" method I make an RPC
call to the server to retrieve the new image data, such that the user
can see his newly changed picture. But there is a problem.
The image in the widget is constructed by
setupWidget() {
....
Image userPicture = new Image( GWT.getHostPageBaseURL() +
umi.userPic.thumbPath );
userPicture.setPixelSize( umi.userPic.width, umi.userPic.height );
...
}
So after having gotten the new image data from the server the method
setupWidget() is called andthe new picture gets the same path as the
old one was, since the "userId".jpg hasn't changed name but content.
The problem: The new image is not reloaded, i.e. the same image as the
old one is shown. But the size of the picture changes. So now I have
the old picture but poorly scaled. I've already tried not to create a
new image but to call "setURL()" on the "old" userpicture. But it
doesn't work either.
Why is the image not reloaded properly?
