Hi,

Just put a breakpoint in your constructor and see what are the stacktraces.

 hi,
 I try to understand why wicket (in 6th version) is constructing my page
 always 3 times per every request. it is page constructor is called 3 times
 always I navigate to page.

 I configured it as

 getResourceSettings().setFileCleaner(null);
 getPageSettings().setVersionPagesByDefault(false);

 getRequestCycleSettings().setRenderStrategy(IRequestCycleSettings.RenderStrategy.REDIRECT_TO_BUFFER);

 unfortunately google cannot find anything on that.

 thanks for help

Wasn't there some problem with empty images (img src= ) and IE
reloading the page? At least I remember some old threads on this topic.

To be honest I do not know the exact reason...  I guess a second request is
launched to retrieve  missing empty image... Just googled for it and
found this.

  yep that was it, why this happens?
 

 To be honest I do not know the exact reason...  I guess a second request is
 launched to retrieve  missing empty image... Just googled for it and

   Wasn't there some problem with empty images (img src= ) and IE
   reloading the page? At least I remember some old threads on this
 topic.
