Duplicate Submit with one click / IndexOutOfBoundsException

Question

Hello all,
When I submit a form to insert data to the database with one button click, the form has been submitted twice. I can see the behavoirs from my debug statements. Sometimes, two records are inserted to database. Sometimes, the "IndexOutOfBoundsException" is throwed. I have downloaded the latest jsf RI. I have tested these many times.
Any help will be appreciated. Thanks in advance.

Hi Sergey,
The javascript:
function checkPassword(form )
     var password = form["editSelfRegister:loginPassword"].value;
     var confirmedPassword = form["editSelfRegister:confirmedPassword"].value;
     if(password != confirmedPassword)
          alert("Login Password and Password Confirm fields do not match ");
          return false;
     else
          form.submit();
          return true;
The command:
<h:commandButton id="saveEditingCommand" value="#{Message.saveEditing}"
actionListener="#{userBean.saveEditingSelfRegisterUser}" onclick="return checkPassword(this.form);" />
<h:commandButton id="cancelCommand" value="#{Message.logout}" action="cancel" immediate="true" />
Even I removed the form.submit(), the form is still submitted twice.
Thank you much for your help.
David
