Page expiration error on AJAX call

[Ondrej Zizka]

Hi,

I have an AjaxEditableLabel wrapped in a component.
After some changes (I'm still finding which), it's behavior gone totally
astray:

On click, it gave me Page Expired every time.
That was happening with 
      this.getPageSettings().setRecreateMountedPagesAfterExpiry(false);
When this is true, it redirects me to an invalid URL - from
http://localhost:8080/essc-portal/release/EAP/5.0.0.GA?10   to
http://localhost:8080/essc-portal/release//?12

The AEL's code is:
<span id="label40" onclick="var
wcall=wicketAjaxGet('./5.0.0.GA?6-1.IBehaviorListener.0-releaseBox-form-traits-releasedBinaries-link-label',function()
 { }.bind(this),function() { }.bind(this), function() {return 
Wicket.$('label40') != null;}.bind(this));">

I have tried everything that came to my mind.

Any ideas what could be wrong?

Thanks,
Ondra
