How to Disable default button

Question

Hi all
I am running on EP 6 SP 9
I have a JSPDynPage with a HTMLB form which has a default button set using the defaultButton attribute of the form
<hbj:button
     id="OKButton"
     text="<%= localString %>"
     width="70"
     design="EMPHASIZED"
     onClick="Search"
     onClientClick="dounload();disableControl(this)"
     >
     <%
      searchForm.setDefaultButton(OKButton);
     %>
</hbj:button>
now in the disableControl method I need to disable the button OKButton.
the following js fuction does exactly that, the button is grayed out and cannot be clicked with the mouse
function disableControl(control){
  control.setDisabled();
however if I press Enter key the form apparently attempts to invoke the eventhandler for this button, this throws a js error: Object doesn't support this property or method
the funny thing is that the line(18) this error occurs on does not contain any js code.
Has anyone had this same problem or is there another way to change the forms default button using js?

I already tried this.
serchForm is undefined in js
adding the line as server side code in the js doesnt work either
<%
  searchForm.setDefaultButton(null);
%>
I also tried to get the form from the control this way in disableControl js function
function disableControl(control){
  control.setDisabled();
  var jsForm = control.form;
  jsForm.setDefaultButton(null);
jsForm is undefined in the last line
does anyone know how to get a reference to the HTMLB form of the page using javascript?
