Java script rendering inside f:subview and s:subForm

When i use subform i get a command link like next.

<a href="#" onclick="clear_formPagina_3Aheader_3AheaderSubform();
document.forms['formPagina:header:headerSubform'].elements['autoScroll'].value=getScrolling();
document.forms['formPagina:header:headerSubform'].elements['formPagina:header:headerSubform:_link_hidden_'].value='formPagina:header:headerSubform:linkLogoutHeader';
if(document.forms['formPagina:header:headerSubform'].onsubmit){var result=document.forms['formPagina:header:headerSubform'].onsubmit();
if( (typeof result == 'undefined') || result ) {document.forms['formPagina:header:headerSubform'].submit();}}
else

return false;"
id="formPagina:header:headerSubform:linkLogoutHeader" class="header_dreapta_logout"></a>

Because of java script error the link is not submited.

Error: clear_formPagina_3Ameniu_3AmeniuSubform is not defined
Source File: http://192.168.2.11:8080/comercial/faces/sec/index.jsp
Line: 1

I have tried today with the last sources from subversion and i get the same error.
The clear method is not rendered anymore.
I have attached a small example.
