Refresh problem?

I have the following problem:
I added a GIF image to a ContentPanel to symbolize the loading of the response from tomcat server that I sent the request via a button.
The first time I send the request, the GIF image is decentralized, but the second time then it centralizes perfectly. This is the code:

Code:

---

ContentPaneltest.removeAll();
ContentPaneltest.layout();
               
LayoutContainer c = new LayoutContainer(); 
VBoxLayout layout = new VBoxLayout(); 
layout.setVBoxLayoutAlign(VBoxLayoutAlign.CENTER); 
layout.setPack(BoxLayoutPack.CENTER);
c.setLayout(layout);
               
Image test = new Image(Utils.URL_LOADING);
c.add(test);
               
ContentPaneltest.add(c);

---

ContentPanel is initialized with the previously FitLayout.
What's wrong?

You should post a fully working testcase that implements EntryPoint. There is probably an issue in the layoutchain.
